@hvadehra I forgot to add the runfiles library to the release archive.

How urgent is this? Do we want to add an integration test in https://github.com/bazelbuild/rules_java/tree/master/test/repo that would have caught something like this?

I'm going to making another release shortly, so happy to merge this now, and get the test in later.

Please remove the "for_bazel_tests" changes

It's needed for bazelbuild/bazel#24219. It's not a hard requirement for Bazel 8 from my point of view, but it could speed up the removal of ruleset deps from bazel_tools if it does get into the release.

I wasn't aware of this setup already existing. I will add a test as part of this PR as it is easy enough.

@hvadehra I added a test.

Could you please fix:

Wrong order for java.nio.file.Path import. 
	//test/repo/src/MyTest.java:8:1
Extra separation in import group before 'mypackage.MyLib' [ImportOrder]
	//test/repo/src/MyTest.java:10:1
Extra separation in import group before 'com.google.devtools.build.runfiles.AutoBazelRepository' [ImportOrder]
	//test/repo/src/MyTest.java:15:1
Wrong order for com.google.devtools.build.runfiles.AutoBazelRepository import.

@hvadehra I ran google-java-format on the file, hope that solves the issues.
