npe when transferring artifacts
-------------------------------
Key: MNG-4864
URL: http://jira.codehaus.org/browse/MNG-4864
Project: Maven 2 & 3
Issue Type: Bug
Affects Versions: 3.0
Reporter: jgon2
I get the following NPE when running a mvn clean install with an empty local
repository. The two stracktraces below show that the build breaks with
different artifacts but always at the same place.
If I relaunch the build several times, it finally succeeds.
