The support core plugin is added to to the BOM, as well as the metrics plugin which is one of its dependencies.

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!

Consistent failures in org.jenkinsci.plugins.workflow.libs.LibraryMemoryTest#loaderReleased. These can be reproduced locally by running:

PLUGINS=workflow-cps-global-lib TEST=org.jenkinsci.plugins.workflow.libs.LibraryMemoryTest\#loaderReleased bash local-test.sh

Happy hunting!
