I’m using the Jenkins plugin GitHub - jenkinsci/JenkinsPipelineUnit: Framework for unit testing Jenkins pipelines to execute our tests, plus we use Gradle.
As our tests grow, we now have the following error:
java.lang.OutOfMemoryError: GC overhead limit exceeded
We execute the command
gradle test --test <test_folder>, which after passing a number of tests, it fails with that error.
It only happens when running over that specific folder, if we run test-by-test, there is no such error.
We already tried to increase the memory limit:
DEFAULT_JVM_OPTS='"-Xmx4g" "-Xms4g" "-XX:+HeapDumpOnOutOfMemoryError" "-XX:+PrintGCDetails" "-verbose:gc" "-XX:MaxMetaspaceSize=350m"'
But we have the same result …
So far, we have no more ideas, only testing file-by-file to avoid that error, but it’s a pure ugly workaround.
Any idea how to avoid the GC overhead limit error?
