3.3.0

Added

  • Included imagePushed field to image metadata json output file which provides information on whether an image was pushed by Jib. Note that the output file is build/jib-image.json by default or configurable with jib.outputPaths.imageJson. (#3641)

Thanks to our community contributors @wwadge, @oliver-brm, @rquinio and @gsquared94!

3.2.1

Added

  • Environment variables can now be used in configuring credential helpers. (#2814) 
     jib.to {
    image = 'myimage'
    credHelper {
        helper = 'ecr-login'
        environment = [
            AWS_PROFILE: 'profile'
        ]
    }
 }

Changed

  • Upgraded jackson-databind to 2.13.2.2 (#3612).

Fixed

  • Fixed setting image format in Kotlin (#3593).

3.2.0

Added

  • jib.from.platforms parameter for multi-architecture image building can now be configured through Maven and system properties (for example, -Djib.from.platforms=linux/amd64,linux/arm64 on the command-line). (#2742)
  • For retrieving credentials, Jib additionally looks for $XDG_RUNTIME_DIR/containers/auth.json, $XDG_CONFIG_HOME/containers/auth.json, and $HOME/.config/containers/auth.json. (#3524)

Changed

  • Changed the default base image of the Jib CLI jar command from the adoptopenjdk images to the eclipse-temurin on Docker Hub. Note that Temurin (by Adoptium) is the new name of AdoptOpenJDK. (#3483)
  • Build will fail if extraDirectories.paths contain from directory that doesn't exist locally (#3542)

Fixed

  • Fixed ClassCastException when using non-String value (for example, Provider) for Main-Class manifest attribute of the jar task. (#3396)
  • Fixed incorrect parsing with comma escaping when providing Jib list or map property values on the command-line. (#2224)

3.1.4

Changed

  • Downgraded Google HTTP libraries to 1.34.0 to resolve network issues. (#3415, #3058, #3409)
  • If allowInsecureRegistries=true, HTTP requests are retried on I/O errors only after insecure failover is finalized for each server. (#3422)

3.1.3

Added

  • Increased robustness in registry communications by retrying HTTP requests (to the effect of retrying image pushes or pulls) on I/O exceptions with exponential backoffs. (#3351)
  • Now also supports username and password properties for the auths section in a Docker config (~/.docker/config.json). (Previously, only supported was a base64-encoded username and password string of the auth property.) (#3365)

Changed

  • Upgraded Google HTTP libraries to 1.39.2. (#3387)

3.1.2

Fixed

  • Fixed the bug introduced in 3.1 that constructs a wrong Java runtime classpath when two dependencies have the same artifact ID and version but different group IDs. The bug occurs only when using Java 9+ or setting jib.container.expandClasspathDependencies. (#3331)

3.1.1

Fixed

  • Fixed the regression introduced in 3.1.0 where a build may fail due to an error from main class inference even if jib.container.entrypoint is configured. (#3295)

3.1.0

Added

  • For Google Artifact Registry (*-docker.pkg.dev), Jib now tries Google Application Default Credentials last like it has been doing for gcr.io. (#3241)
  • Added lazy evaluation for jib.container.labels using Gradle Property and Provider. (#3242)

Changed

  • Jib now creates an additional layer that contains two small text files: /app/jib-classpath-file and /app/jib-main-class-file. They hold, respectively, the final Java runtime classpath and the main class computed by Jib that are suitable for app execution on JVM. For example, with Java 9+, setting the container entrypoint to java --class-path @/app/jib-classpath-file @/app/jib-main-class-file will work to start the app. (This is basically the default entrypoint set by Jib when the entrypoint is not explicitly configured by the user.) The files are always generated whether Java 8 or 9+, or whether jib.container.entrypoint is explicitly configured. The files can be helpful especially when setting a custom entrypoint for a shell script that needs to get the classpath and the main class computed by Jib, or for AppCDS. (#3280)
  • For Java 9+ apps, the default Java runtime classpath explicitly lists all the app dependencies, preserving the dependency loading order declared by Gradle. This is done by changing the default entrypoint to use the new classpath JVM argument file (basically java -cp @/app/jib-classpath-file). As such, jib.container.expandClasspathDependencies takes no effect for Java 9+. (#3280)
  • Timestamps of file entries in a tarball built with jibBuildTar are set to the epoch, making the tarball reproducible. (#3158)

3.0.0

Added

  • New includes and excludes options for jib.extraDirectories. This enables copying a subset of files from the source directory using glob patterns. (#2564)
  • Added an option configurationName to specify the name of the Gradle Configuration to use. The option can be lazily configured, for example, using Gradle Provider or Property. (#3034)
    jib {
      configurationName = 'myconfig'
    }

Changed

Fixed

  • Fixed an issue where some log messages used color in the "plain" console output. (#2764)

2.8.0

Added

Changed

2.7.1

Fixed

  • Updated jackson dependency version causing compatibility issues. (#2931)
  • Deprecated use of @Optional on boolean attribute (#2930)

2.7.0

Added

  • Added an option jib.container.expandClasspathDependencies to preserve the order of loading dependencies as configured in a project. The option enumerates dependency JARs instead of using a wildcard (/app/libs/*) in the Java runtime classpath for an image entrypoint. (#1871, #1907, #2228, #2733)
    • The option is also useful for AppCDS. (#2471)
    • Turning on the option may result in a very long classpath string, and the OS may not support passing such a long string to JVM.
  • Added lazy evaluation for jib.(to|from).auth.(username|password) and jib.from.image using Gradle Property and Provider. (#2905)

Fixed

  • Fixed NullPointerException when pulling an OCI base image whose manifest does not have mediaType information. (#2819)
  • Fixed build failure when using a Docker daemon base image (docker://...) that has duplicate layers. (#2829)

2.6.0

Added

  • Added lazy evaluation for jib.to.image and jib.to.tags using Gradle Property and Provider. (#2727)
  • Incubating feature: can now configure multiple platforms (such as architectures) to build multiple images as a bundle and push as a manifest list (also known as a fat manifest). As an incubating feature, there are certain limitations. For example, OCI image indices are not supported, and building a manifest list is supported only for registry pushing (the jib task). (#2523) 
    jib.from {
  image = '... image reference to a manifest list ...'
  platforms {
    platform {
      architecture = 'arm64'
      os = 'linux'
    }
  }
}

Changed

  • Previous locally cached base image manifests will be ignored, as the caching mechanism changed to enable multi-platform image building. (#2730, #2711)
  • Upgraded the ASM library to 9.0 to resolve an issue when auto-inferring main class in Java 15+. (#2776)

Fixed

  • Fixed NullPointerException during input validation (in Java 9+) when configuring Jib parameters using certain immutable collections (such as List.of()). (#2702)
  • Fixed authentication failure with Azure Container Registry when using "tokens". (#2784)
  • Improved authentication flow for base image registry. (#2134)
  • Throw IllegalArgumentException with an error message instead of throwing a NullPointerException when jib.to.tags is set to a collection containing a null value. (#2760)

2.5.1

Fixed

  • Fixed an issue that configuring jib.from.platforms was always additive to the default amd64/linux platform. (#2783)

2.5.0

Added

  • Also tries .exe file extension for credential helpers on Windows. (#2527)
  • New system property jib.skipExistingImages (false by default) to skip pushing images (manifests) if the image already exists in the registry. (#2360)
  • Incubating feature: can now configure desired platform (architecture and OS) to select the matching manifest from a Docker manifest list. Currently supports building only one image. OCI image indices are not supported. (#1567) 
    jib.from {
  image = '... image reference to a manifest list ...'
  platforms {
    platform {
      architecture = 'arm64'
      os = 'linux'
    }
  }
}

Fixed

  • Fixed reporting a wrong credential helper name when the helper does not exist on Windows. (#2527)
  • Fixed NullPointerException when the "auths": section in ~/.docker/config.json has an entry with no "auth": field. (#2535)
  • Fixed NullPointerException to return a helpful message when a server does not provide any message in certain error cases (400 Bad Request, 404 Not Found, and 405 Method Not Allowed). (#2532)
  • Now supports sending client certificate (for example, via the javax.net.ssl.keyStore and javax.net.ssl.keyStorePassword system properties) and thus enabling mutual TLS authentication. (#2585, #2226)
  • Fixed an issue where Jib cannot infer Kotlin main class that takes no arguments. (#2666)

2.4.0

Added

  • Jib Extension Framework! The framework enables anyone to easily extend and tailor the Jib Gradle plugin behavior to their liking. Check out the new Jib Extensions GitHub repository to learn more. (#2401)
  • Project dependencies in a multi-module WAR project are now stored in a separate "project dependencies" layer (as currently done for a non-WAR project). (#2450)

Changed

  • Previous locally cached application layers (<project root>/target/jib-cache) will be ignored because of changes to the caching selectors. (#2499)

Fixed

  • Fixed authentication failure with Azure Container Registry when using an identity token defined in the auths section of Docker config (~/.docker/config.json). (#2488)

2.3.0

Added

  • jib.extraDirectories.paths closure to allow configuring the source and target of an extra directory. (#1581)

Fixed

  • Fixed the problem not inheriting USER container configuration from a base image. (#2421)
  • Fixed wrong capitalization of JSON properties in a loadable Docker manifest when building a tar image. (#2430)
  • Fixed an issue when using a base image whose image creation timestamp contains timezone offset. (#2428)
  • Fixed an issue inferring a wrong main class or using an invalid main class (for example, Spring Boot project containing multiple main classes). (#2456)

2.2.0

Added

  • Glob pattern support for jib.extraDirectories.permissions. (#1200)
  • Support for image references with both a tag and a digest. (#1481)
  • The DOCKER_CONFIG environment variable specifying the directory containing docker configs is now checked during credential retrieval. (#1618)
  • Also tries .cmd file extension for credential helpers on Windows. (#2399)

Changed

  • jib.container.creationTime now accepts more timezone formats:+HHmm. This allows for easier configuration of creationTime by external systems. (#2320)

2.1.0

Added

  • Additionally reads credentials from ~/.docker/.dockerconfigjson and legacy Docker config (~/.docker/.dockercfg). Also searches for $HOME/.docker/* (in addition to current System.get("user.home")/.docker/*). This may help retrieve credentials, for example, on Kubernetes. (#2260)
  • New skaffold configuration options that modify how jib's build config is presented to skaffold (#2292):
    • jib.skaffold.watch.buildIncludes: a list of build files to watch
    • jib.skaffold.watch.includes: a list of project files to watch
    • jib.skaffold.watch.excludes: a list of files to exclude from watching
    • jib.skaffold.sync.excludes: a list of files to exclude from sync'ing

Fixed

  • Fixed authentication failure with error server did not return 'WWW-Authenticate: Bearer' header in certain cases (for example, on OpenShift). (#2258)
  • Fixed an issue where using local Docker images (by docker://...) on Windows caused an error. (#2270)
  • Fixed build failures with Skaffold when the Gradle Java Platform plugin is applied. (#2269)
  • For Spring Boot projects using containerizingMode = 'packaged', Jib now overrides archiveClassifier of the jar task only when safe and necessary. (#2278)
  • Fixed an issue where user-configured task dependencies for the Jib task is overwritten and thus ineffective. (#2289)

2.0.0

Added

  • Added json output file for image metadata after a build is complete. Writes to build/jib-image.json by default, configurable with jib.outputPaths.imageJson. (#2227)
  • Added automatic update checks. Jib will now display a message if there is a new version of Jib available. See the privacy page for more details. (#2193)

Changed

  • Removed jibDockerBuild.dockerClient in favor of jib.dockerClient. (#1983)
  • Removed deprecated jib.extraDirectory configuration in favor of jib.extraDirectories. (#1691)
  • Removed deprecated jib.container.useCurrentTimestamp configuration in favor of jib.container.creationTime with USE_CURRENT_TIMESTAMP. (#1897)
  • HTTP redirection URLs are no longer sanitized in order to work around an issue with certain registries that do not conform to HTTP standards. This resolves an issue with using Red Hat OpenShift and Quay registries. (#2106, #1986)
  • Requires Gradle 5.1 or newer (up from 4.9).
  • The default base image cache location has been changed on MacOS and Windows. (#2216)
    • MacOS ($XDG_CACHE_HOME defined): from $XDG_CACHE_HOME/google-cloud-tools-java/jib/ to $XDG_CACHE_HOME/Google/Jib/
    • MacOS ($XDG_CACHE_HOME not defined): from $HOME/Library/Application Support/google-cloud-tools-java/jib/ to $HOME/Library/Caches/Google/Jib/
    • Windows ($XDG_CACHE_HOME defined): from $XDG_CACHE_HOME\google-cloud-tools-java\jib\ to $XDG_CACHE_HOME\Google\Jib\Cache\
    • Windows ($XDG_CACHE_HOME not defined): from %LOCALAPPDATA%\google-cloud-tools-java\jib\ to %LOCALAPPDATA%\Google\Jib\Cache\
    • Initial builds will be slower until the cache is repopulated, unless you manually move the cache from the old location to the new location

Fixed

  • jibBuildTar with jib.container.format='OCI' now builds a correctly formatted OCI archive. (#2124)
  • Now jib.containerizingMode='packaged' works as intended with Spring Boot projects that generate a fat JAR. (#2178)
  • Now automatically refreshes Docker registry authentication tokens when expired, fixing the issue that long-running builds may fail with "401 unauthorized." (#691)

1.8.0

Changed

  • Requires Gradle 4.9 or newer (up from 4.6).
  • Optimized building to a registry with local base images. (#1913)

Fixed

  • Fixed reporting parent build file when skaffold init is run on multi-module projects. (#2091)
  • Now correctly uses the war task if it is enabled and the bootWar task is disabled for Spring WAR projects. (#2096)
  • allowInsecureRegistries and the sendCredentialsOverHttp system property are now effective for authentication service server connections. (#2074)
  • Fixed inefficient communications when interacting with insecure registries and servers (when allowInsecureRegistries is set). (#946)

1.7.0

Added

  • jib.outputPaths object for configuration output file locations (#1561)
    • jib.outputPaths.tar configures output path of jibBuildTar (build/jib-image.tar by default)
    • jib.outputPaths.digest configures the output path of the image digest (build/jib-image.digest by default)
    • jib.outputPaths.imageId configures output path of the image id (build/jib-image.id by default)
  • Main class inference support for Java 13/14. (#2015)

Changed

  • Local base image layers are now processed in parallel, speeding up builds using large local base images. (#1913)
  • The base image manifest is no longer pulled from the registry if a digest is provided and the manifest is already cached. (#1881)
  • Docker daemon base images are now cached more effectively, speeding up builds using docker:// base images. (#1912)

Fixed

  • Fixed temporary directory cleanup during builds using local base images. (#2016)
  • Fixed additional tags being ignored when building to a tarball. (#2043)
  • Fixed tar:// base image failing if tar does not contain explicit directory entries. (#2067)

1.6.1

Fixed

  • Fixed an issue with using custom base images in Java 12+ projects. (#1995)

1.6.0

Added

  • Support for local base images by prefixing jib.from.image with docker:// to build from a docker daemon image, or tar:// to build from a tarball image. (#1468, #1905)

Changed

  • To disable parallel execution, the property jib.serialize should be used instead of jibSerialize. (#1968)
  • For retrieving credentials from Docker config (~/.docker/config.json), credHelpers now takes precedence over credsStore, followed by auths. (#1958)
  • The legacy credsStore no longer requires defining empty registry entries in auths to be used. This now means that if credsStore is defined, auths will be completely ignored. (#1958)
  • jib.dockerClient is now configurable on all tasks, not just jibDockerBuild. (#1932)
  • jibDockerBuild.dockerClient is deprecated in favor of jib.dockerClient.

Fixed

  • Fixed the regression of slow network operations introduced at 1.5.0. (#1980)
  • Fixed an issue where connection timeout sometimes fell back to attempting plain HTTP (non-HTTPS) requests when allowInsecureRegistries is set. (#1949)

1.5.1

Fixed

  • Fixed an issue interacting with certain registries due to changes to URL handling in the underlying Apache HttpClient library. (#1924)

1.5.0

Added

  • Can now set timestamps (last modified time) of the files in the built image with jib.container.filesModificationTime. The value should either be EPOCH_PLUS_SECOND to set the timestamps to Epoch + 1 second (default behavior), or an ISO 8601 date time parsable with DateTimeFormatter.ISO_DATE_TIME such as 2019-07-15T10:15:30+09:00 or 2011-12-03T22:42:05Z. (#1818)
  • Can now set container creation timestamp with jib.container.creationTime. The value should be EPOCH, USE_CURRENT_TIMESTAMP, or an ISO 8601 date time. (#1609)
  • For Google Container Registry (gcr.io), Jib now tries Google Application Default Credentials (ADC) last when no credentials can be retrieved. ADC are available on many Google Cloud Platform (GCP) environments (such as Google Cloud Build, Google Compute Engine, Google Kubernetes Engine, and Google App Engine). Application Default Credentials can also be configured with gcloud auth application-default login locally or through the GOOGLE_APPLICATION_CREDENTIALS environment variable. (#1902)

Changed

  • When building to a registry, Jib now skips downloading and caching base image layers that already exist in the target registry. This feature will be particularly useful in CI/CD environments. However, if you want to force caching base image layers locally, set the system property -Djib.alwaysCacheBaseImage=true. (#1840)
  • jib.container.useCurrentTimestamp has been deprecated in favor of jib.container.creationTime with USE_CURRENT_TIMESTAMP. (#1609)

1.4.0

Added

  • Can now containerize a JAR artifact instead of putting individual .class and resource files with jib.containerizingMode = 'packaged'. (#1760)
  • Now automatically supports WAR created by the Spring Boot Gradle Plugin via the bootWar task. (#1786)
  • Can now use jib.from.image = 'scratch' to use the scratch (empty) base image for builds. (#1794)

Changed

  • Dependencies are now split into three layers: dependencies, snapshots dependencies, project dependencies. (#1724)

Fixed

  • Re-enabled cross-repository blob mounts. (#1793)
  • Manifest lists referenced directly by sha256 are automatically parsed and the first linux/amd64 manifest is used. (#1811)

1.3.0

Changed

  • Docker credentials (~/.docker/config.json) are now given priority over registry-based inferred credential helpers. (#1704)

Fixed

  • Fixed an issue with jibBuildTar where UP-TO-DATE checks were incorrect. (#1757)

1.2.0

Added

  • Container configurations in the base image are now propagated when registry uses the old V2 image manifest, schema version 1 (such as Quay). (#1641)
  • Can now prepend paths in the container to the computed classpath with jib.container.extraClasspath. (#1642)
  • Can now build in offline mode using --offline. (#718)
  • Now supports multiple extra directories with jib.extraDirectories.{paths|.permissions}. (#1020)

Changed

  • jib.extraDirectory({.path|.permissions}) are deprecated in favor of the new jib.extraDirectories.{paths|.permissions} configurations. (#1671)

Fixed

  • Labels in the base image are now propagated. (#1643)
  • Fixed an issue with using OCI base images. (#1683)

1.1.2

Fixed

  • Fixed an issue where automatically generated parent directories in a layer did not get their timestamp configured correctly to epoch + 1s. (#1648)

1.1.1

Fixed

  • Fixed an issue where the plugin creates wrong images by adding base image layers in reverse order when registry uses the old V2 image manifest, schema version 1 (such as Quay). (#1627)

1.1.0

Changed

  • os and architecture are taken from base image. (#1564)

Fixed

  • Fixed an issue where pushing to Docker Hub fails when the host part of an image reference is docker.io. (#1549)

1.0.2

Added

  • Java 9+ WAR projects are now supported and run on the distroless Jetty Java 11 image (https://github.com/GoogleContainerTools/distroless) by default. Java 8 projects remain on the distroless Jetty Java 8 image. (#1510)
  • Now supports authentication against Azure Container Registry using docker-credential-acr-* credential helpers. (#1490)

Fixed

  • Fixed an issue where setting allowInsecureRegistries may fail to try HTTP. (#1517)
  • Crash on talking to servers that do not set the Content-Length HTTP header or send an incorrect value. (#1512)

1.0.1

Added

Fixed

  • Failure to infer main class when main method is defined using varargs (i.e. public static void main(String... args)). (#1456)

1.0.0

Changed

  • Shortened progress bar display - make sure console window is at least 50 characters wide or progress bar display can be messy. (#1361)

1.0.0-rc2

Added

  • Setting proxy credentials (via system properties http(s).proxyUser and http(s).proxyPassword) is now supported.

Changed

  • Java 9+ projects using the default distroless Java 8 base image will now fail to build. (#1143)

1.0.0-rc1

Added

  • jib.baseImageCache and jib.applicationCache system properties for setting cache directories. (#1238)
  • Build progress shown via a progress bar - set -Djib.console=plain to show progress as log messages. (#1297)

Changed

  • Removed jib.useOnlyProjectCache parameter in favor of the jib.useOnlyProjectCache system property. (#1308)

Fixed

  • Builds failing due to dependency JARs with the same name. (#810)

0.10.1

Added

  • Image ID is now written to build/jib-image.id. (#1204)
  • jib.container.entrypoint = 'INHERIT' allows inheriting ENTRYPOINT and CMD from the base image. While inheriting ENTRYPOINT, you can also override CMD using jib.container.args.
  • container.workingDirectory configuration parameter to set the working directory. (#1225)
  • Adds support for configuring volumes. (#1121)
  • Exposed ports are now propagated from the base image. (#595)
  • Docker health check is now propagated from the base image. (#595)

Changed

Fixed

  • NullPointerException thrown with incomplete auth configuration. (#1177)

0.10.0

Added

  • Properties for each configuration parameter, allowing any parameter to be set via commandline. (#1083)
  • jib.to.credHelper and jib.from.credHelper can be used to specify a credential helper suffix or a full path to a credential helper executable. (#925)
  • container.user configuration parameter to configure the user and group to run the container as. (#1029)
  • Preliminary support for building images for WAR projects. (#431)
  • jib.extraDirectory closure with a path and permissions field. (#794)
    • jib.extraDirectory.path configures the extra layer directory (still also configurable via jib.extraDirectory = file(...))
    • jib.extraDirectory.permissions is a map from absolute path on container to the file's permission bits (represented as an octal string).
  • Image digest is now written to build/jib-image.digest. (#933)
  • Adds the layer type to the layer history as comments. (#1198)
  • jibDockerBuild.dockerClient.executable and jibDockerBuild.dockerClient.environment to set Docker client binary path (defaulting to docker) and additional environment variables to apply when running the binary. (#1214)

Changed

  • Removed deprecated jib.jvmFlags, jib.mainClass, jib.args, and jib.format in favor of the equivalents under jib.container. (#461)

0.9.5

Added

  • Incubating feature to build src/main/jib as extra layer in image. (#562)

0.9.4

Fixed

  • Fixed handling case-insensitive Basic authentication method. (#546)
  • Fixed regression that broke pulling base images from registries that required token authentication. (#549)

Fixed

  • Using Docker config for finding registry credentials (was not ignoring extra fields and handling https protocol). (#524)

0.9.2

Added
