I can confirm: It is working, thank you!
I have seen a pull request which might fix the problem: https://github.com/checkstyle/checkstyle/pull/5245
thank you for your effort debugging this issue! do you think eclipse-cs could workaround this issue or do we have to wait for a solution from the checkstyle maintainers?
I made some changes (i.e. adding plugin.xml) in the jar and now I get my package (with correct dots) in the error message, but it is still not loaded. So the checkstyle-metadata.xml is loading correct. Any ideas?
I think the problem with loading is an eclipse-cs problem. Because as I already mentioned, I've upgraded the inheritance in https://github.com/bjrke/JSR305CheckstylePlugin/commit/e5fdf3c1340dbeb9bd5db79b9ad5448418b8dbb4 and I've tests against all known working checkstyle versions, including 8.0 and 8.1. But I didn't released yet since eclipse-cs is not working. To do more tests I need to setup a new environment because I need my eclipse for daily work.
I've included tests against checkstyle 8 which are working well: https://travis-ci.org/bjrke/JSR305CheckstylePlugin When I upgrade the gradle build of our big project to Checkstyle 8.0 it is working with a dev version of the plugin, too. But I'll investigate the missing dot, perhaps there is a strange configuration issue.
I can confirm this problem with another Plugin which was working before the upgrade to 8.0: https://github.com/bjrke/JSR305CheckstylePlugin !ENTRY net.sf.eclipsecs.core 4 0 2017-07-31 12:53:19.062 !MESSAGE Checkstyle-Plugin: cannot initialize module TreeWalker - Unable to instantiate 'Jsr305Annotations' class, it is also not possible to instantiate it as com.puppycrawl.tools.checkstyle.checks.annotationJsr305Annotations, com.puppycrawl.tools.checkstyle.checks.blocksJsr305Annotations, com.puppycrawl.tools.checkstyle.checks.codingJsr305Annotations,...
