Kristian Rosenvold commented on MSHADE-171:
-------------------------------------------
Additional resource leaks have just been fixed in jdependency, so we'd need to
wait for a release of a version >1.0
> "Access Denied" on Windows because shade plugin seems to try to open a
> directory as Zip-File
> --------------------------------------------------------------------------------------------

> Key: MSHADE-171
> URL: https://issues.apache.org/jira/browse/MSHADE-171
> Project: Maven Shade Plugin
> Issue Type: Bug
> Affects Versions: 2.3
> Environment: Happens on both Windows and Linux
> Reporter: Dominik Stadler
> Fix For: backlog
>
> Attachments: MSHADE-171.zip

> Config of plugin is fairly simple, but fails with the error below when I call
> "mvn package test", it works when I call only "mvn package", it seems the
> plugin tries to open a directory as zip-file.
> It happens in a multi-module setup when building from the parent-directory.
> It seems the dependency between the module where the shade plugin runs onto
> another module causes the target/classes of that module to be added as
> artifact-file, which causes the shade plugin to fail.
> Let me know if you need a self-contained reproducer project, I can provide
> one, but it will take some time to build it...
> FYI, there was a similar problem in the war plugin at MWAR-192.
