             Summary: Adding repository error running mvn clean
                 Key: MNG-5532
                 URL: https://jira.codehaus.org/browse/MNG-5532
             Project: Maven 2 & 3
          Issue Type: Bug
          Components: Artifacts and Repositories
    Affects Versions: 3.1.1
         Environment: Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 11:22:22-0400)

         Attachments: debug.log

Problem:
While running "mvn clean" I receive some exceptions while:
Adding repository http://download.eclipse.org/eclipse/updates/license
The -X debug output has been attached to see the full error. I've also provided instructions on how I receive this error.

The first exception is:
java.lang.ClassCastException: org.eclipse.tycho.p2.remote.RemoteMetadataRepositoryManager cannot be cast to org.eclipse.equinox.internal.p2.metadata.repository.MetadataRepositoryManager

I have to admit that I'm pretty new to building eclipse and using maven. My apologies if this is not a valid bug. I'm doing some more research to see if I am missing something.

I'm not clear whether this is a problem with Maven or the maybe the POM. I'm opening the bug under Maven since I found this at the end of the error:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/InternalErrorException

I believe I received something similar while using the eclipse plugin so decided to download/use apache maven outside of eclipse to see if i received the same problem. After extracting maven, changing some maven environment variables, i re-extracted the zip i downloaded and tried using the mvn binary. But it looks like it failed in the same place. 

STEPS TO REPRODUCE:
1. Go to http://download.eclipse.org/eclipse/downloads/drops4/R-4.3.1-201309111000/
2. click the link for "View the repositories used for the current build." 
3. copy/paste the URL for: http://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/commit?id=629251e64d8bebd34caca0939ee2e4c460eee609
4. download the file: 	eclipse.platform.releng.aggregator-629251e64d8bebd34caca0939ee2e4c460eee609.zip
5. rename my existing .m2 repository folder to .m2.old (because I had a bunch of stuff in there from training stuff).
6. extract the file from step 4 to my C:\apache-maven-3.1.1 directory.
7. open a command prompt and cd to the directory:  C:\apache-maven-3.1.1\eclipse.platform\eclipse.platform.releng.tychoeclipsebuilder\platform
8. run: mvn clean
9. receive error while:
Adding repository http://download.eclipse.org/eclipse/updates/license

Kind regards,
Gregg
