### Bug Description When adding s390x and ppc64el as test platforms, the Gradle integration tests don't appear to work. It is not clear to me what is failing, but I presume no actual jar files are being generated. ### To Reproduce Run the following on s390x or ppc64el (possibly also riscv64): ``` pytest tests/integration/plugins/test_gradle.py::test_gradle_plugin_gradlew ``` ### part yaml ```shell ``` ### Relevant log output ```shell _______________________ test_gradle_plugin_gradlew[none] _______________________ new_dir = local('/tmp/pytest-of-ubuntu/pytest-0/test_gradle_plugin_gradlew_non0') testing_source_dir = local('/tmp/pytest-of-ubuntu/pytest-0/test_gradle_plugin_gradlew_non0') partitions = None, local_proxy_url = 'http://localhost:8888' def test_gradle_plugin_gradlew( new_dir, testing_source_dir, partitions, local_proxy_url ): part_name = "foo" parts_yaml = textwrap.dedent( f""" parts: {part_name}: plugin: gradle gradle-task: testWrite build gradle-init-script: init.gradle source: {testing_source_dir} build-packages: [gradle, openjdk-21-jdk] build-environment: # This is just because the test environment has multiple java versions and will # use default-jre if unspecified. - JAVA_HOME: /usr/lib/jvm/java-21-openjdk-${{CRAFT_ARCH_BUILD_FOR}} - http_proxy: {local_proxy_url} - https_proxy: {local_proxy_url} # Set GRADLE_USER_HOME dir to the according part's build .gradle dir to avoid # interfering with other tests. - GRADLE_USER_HOME: {new_dir}/parts/{part_name}/build/.gradle stage-packages: [openjdk-21-jdk] """ ) parts = yaml.safe_load(parts_yaml) lf = LifecycleManager( parts, application_name="test_ant", cache_dir=new_dir, work_dir=new_dir, partitions=partitions, ) actions = lf.plan(Step.PRIME) with lf.action_executor() as ctx: ctx.execute(actions) _test_core_gradle_plugin_build_output(project_info=lf.project_info) # generated by the init.gradle testWrite task > assert (lf.project_info.dirs.parts_dir / f"{part_name}/build" / "test.txt").exists() E AssertionError: assert False E + where False = exists() E + where exists = ((PosixPath('/tmp/pytest-of-ubuntu/pytest-0/test_gradle_plugin_gradlew_non0/parts') / 'foo/build') / 'test.txt').exists E + where PosixPath('/tmp/pytest-of-ubuntu/pytest-0/test_gradle_plugin_gradlew_non0/parts') = <craft_parts.dirs.ProjectDirs object at 0x7e81fdc14ce0>.parts_dir E + where <craft_parts.dirs.ProjectDirs object at 0x7e81fdc14ce0> = <craft_parts.infos.ProjectInfo object at 0x7e81fc9b5070>.dirs E + where <craft_parts.infos.ProjectInfo object at 0x7e81fc9b5070> = <craft_parts.lifecycle_manager.LifecycleManager object at 0x7e81fdd47860>.project_info /home/ubuntu/actions-runner/_work/craft-parts/craft-parts/tests/integration/plugins/test_gradle.py:112: AssertionError ------------------------------ Captured log setup ------------------------------ WARNING root:features.py:42 deleting current features configuration ----------------------------- Captured stdout call ----------------------------- Downloading https://services.gradle.org/distributions/gradle-8.13-bin.zip ..................................................................................................................................
