------------------------------------

             Summary: LinkageError when CDI is in the classpath 
                 Key: MNG-5620
                 URL: https://jira.codehaus.org/browse/MNG-5620
             Project: Maven 2 & 3
          Issue Type: Bug
          Components: General
    Affects Versions: 3.2.1, 3.1.1, 3.1.0, 3.1.0-alpha-1
            Reporter: Martin Grigorov


We have troubles use 'mvn jetty:run' for https://github.com/apache/wicket/tree/master/wicket-examples after upgrading to Maven 3.1.0+.

It fails with:

The issue is not new. We just noticed that when using 3.0.5 it runs fine so it should be some change in Maven itself.

I've found that another user had the same issue:  http://stackoverflow.com/a/18168215/497381

How to reproduce:
1) git clone https://github.com/apache/wicket.git
2) mvn install (just to have all dependencies)
3) cd wicket-examples
4) mvn jetty:run (fails with 3.1.0+)
