["Greg Luck (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MSHADE-30?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=141623#action_141623 ] 

Greg Luck commented on MSHADE-30:
---------------------------------

I have the same problem.

It will sometimes do a mvn package for me. But I cannot ever get install or deploy to work. 

I tested versions going back to the 1.0 alphas. They all have the problem.

It would be really really great to get this fixed.

>             Project: Maven 2.x Shade Plugin
>          Issue Type: Bug
>    Affects Versions: 1.0.1

> I receive this error:
> Embedded error: duplicate entry: org/apache/xmlbeans/FilterXmlObject.class
> It started with a javax.xml.namespace class.  So I started putting excludes, and then I kept getting one new class after another.  If I exclude everything then I doubt my application is going to work.
> I really don't understand this error.  I have never seen this type of error with the fatjar eclipse plugin.  I understand it's complaining about having the same class twice, but if it's not a problem for my eclipse project or the maven build, why is it a problem for shade?
> I feel the shade plugin should be able to handle this gracefully.
