unable to build simple android project

[smacz]

Hello,

I'm totally new to this so please cut me some slack.

I run this image, create project with

flutter create -t app --platform android test_app

then cd into it and run

flutter build apk

this is what I get

# flutter build apk

Issue: Gradle Daemon Crashing and Slow Builds in Bitbucket Pipeline

I am using the Docker image ghcr.io/cirruslabs/flutter:3.24.5 in my Bitbucket Pipeline. The Gradle build process takes a long time to initialize (~5 minutes), and then fails unexpectedly without a detailed error message. Below are the relevant logs:

[04:45:33]: ▸ Changing current working directory to: /opt/atlassian/pipelines/agent/build
[04:51:48]: ▸ Running Gradle task 'assembleDevRelease'...
[04:51:48]: ▸ Checking the license for package Android SDK Build-Tools 33.0.1 in /opt/android-sdk-linux/licenses
[04:51:48]: ▸ License for package Android SDK Build-Tools 33.0.1 accepted.
[04:55:13]: ▸ FAILURE: Build failed with an exception.
[04:55:13]: ▸ * What went wrong:
[04:55:13]: ▸ Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)
[04:55:13]: ▸ * Try:
[04:55:13]: ▸ > Run with --stacktrace option to get the stack trace.
[04:55:13]: ▸ > Run with --info or --debug option to get more log output.

This issue consistently occurs during the Gradle task execution, with no clear stack trace or debug information provided. The pipeline ends with a Gradle task assembleDevRelease failed with exit code 1.

@dhruvin207 Are you found a solution ?

The source problem appeared as a warning when you create your app - android build can only run with java 17, while the image has java 21.

Markers are mine.

$ flutter create -t app --platform android test_app
Creating project test_app...
...
All done!
...

In order to run your application, type:

$ cd test_app
$ flutter run

Your application code is in test_app/lib/main.dart.

The configured version of Java detected may conflict with the Gradle version in your new Flutter app.

To keep the default AGP version Gradle version 8.3, download a compatible Java version
(Java 17 <= (Java 17 <= compatible Java version < Java 21) Java version < Java 21). Configure this Java version
globally for Flutter by running:

flutter config --jdk-dir=<JDK_DIRECTORY>

...

$

$ apt install openjdk-17-jre openjdk-17-jdk
...
$ flutter config --jdk-dir /usr/lib/jvm/java-17-openjdk-amd64/
...
$ flutter build apk
...
Running Gradle task 'assembleRelease'... 172.9s
✓ Built build/app/outputs/flutter-apk/app-release.apk (18.8MB)
$

android docs also very clear about it - only openjdk-17 is supported

@fkorotkov can you verify this and downgrade java versions for next releases?

I'm running in to the same issue. It looks like the Android 34 image on which this is based was updated to use openjdk-21 here: cirruslabs/docker-images-android@90d9542
