             Summary: "Access Denied" on Windows because shade plugin seems to try to open a directory as Zip-File
                 Key: MSHADE-171
                 URL: https://jira.codehaus.org/browse/MSHADE-171
             Project: Maven Shade Plugin
          Issue Type: Bug
    Affects Versions: 2.3
         Environment: Happens on Windows, works fine on Linux
            Reporter: Dominik Stadler


Config of plugin is fairly simple, the same works on Linux, but consistently fails on Windows with the error below, seems the plugin tries to open a directory as zip-file.

Let me know if you need a self-contained reproducer project, I can provide one, but it will take some time to build it...
