James Nord created MPLUGIN-449:
----------------------------------

             Summary: spurious warning when unpacking dependencies on windows.
                 Key: MPLUGIN-449
                 URL: https://issues.apache.org/jira/browse/MPLUGIN-449
             Project: Maven Plugin Tools
          Issue Type: Bug
          Components: maven-plugin-tools-annotations
    Affects Versions: 3.7.0
            Reporter: James Nord


when running on windows and searching dependencies for annotations the mojo emits a large amount of warnings as there is a case issue in the dependencies.

However there is no case issue as can be seen with inspection and this is a bug in the version of the plexus archiver that is in use.

upgrading the version of the plexus-archiver dependency in the plugin definition fixes this warning.

can be observed with the tree dc277b661f9a8da78136d2b0d7865e50569f2820  in  https://github.com/jenkinsci/maven-hpi-plugin 

workaround is to add the archiver dependency to a newer version in the projects pom - but this should not be needed.
