Bug: sam build can't check the JVM version on gradle >= v8.9

[jeffryang24]

Description:

Previously, sam build does not show this warning message when building using Gradle, but somehow this message appears in the new Gradle version.

failed to return a version string using the '-v' option. The workflow is unable to check that the version of the JVM used is compatible with AWS Lambda.

Steps to reproduce:

1. Update the project gradle version to >= v8.9 (8.9 or 8.10).
2. Run sam build on existing SAM application project.

Observed result:

Got above error message while the build process is successfully executed.

Expected result:

Don't show above error message since the JVM version should be available from gradlew -v command.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

After testing with older Gradle version (below v8.8), found out the gradle output for JVM has different label.

• Gradle < v8.9 is using JVM label,
• while Gradle >= v8.9 is using Launcher JVM or Daemon JVM label.

Gradle < v8.9

Use gradle v8.8 as example, current sam-cli integration test is using v8.4.

❯ ./gradlew --version
