Drop the requirement of jvm environment variables for `testJvm` constraint by bric3 · Pull Request #9968 · DataDog/dd-trace-java

bric3 · 2025-11-14T11:45:46Z

What Does This Do

Allow our testJvmContraint plugin to let Gradle find the relevant JVM using the Gradle Toolchain.

Also, in CI, discover dynamically the JAVA_x_HOME environment variables exposed by the DataDog/dd-trace-java-docker-build image.

Motivation

Easier local setup. And follow-up to

Drop fromEnv toolchain restriction for local environment #9950

-      if (javaVersions.isEmpty()) {
-        throw GradleException("No valid JAVA_X_HOME environment variables found.")
+    when (testJvm) {
+      "stable" -> {


Could we rename stable -> latest? or similar? stable is kind of misleading to me, WDYT?

I'm hesitant to that right now, as there were prior discussions on this.

Maybe we can have both, like lastStable :D

buildSrc/src/main/kotlin/datadog/gradle/plugin/testJvmConstraints/TestJvmSpec.kt

+ * Handles the `testJvm` property to resolve a Java launcher for testing.
+ *
+ * The `testJvm` property can be set via command line or environment variable to specify
+ * which JVM to use for running tests. E.g.
+ *
+ * ```shell
+ * ./gradlew test -DtestJvm=ZULU11
+ * ```


I wish we have TESTING.md with all this useful documentation from this class :)

Exactly, I started the kdoc here, so we can reuse this text for such a file.
