We don't actually need
-PenableCrossCompilerPlugin=true
inbuild.yml
orrelease.yml
(it's turned on already by the Nebula plugin since we're making a candidate build) but I thought it was worth adding for clarity.For the GitHub workflows, I didn't know a great way to test it, so I first read setup-java to determine how the
$PATH
manipulation works, then I tested it withpr.yml
by:Optional#stream()
) and seeing the build fail (proving we're compiling against the Java 8 APIs)-PenableCrossCompilerPlugin=false
and watching the build succeed (proving we're using the Java 11javac
)
