maven release:prepare with artifactory deploy substep fails - maven

Question

after researching now for days and close to suicidal tendencies here my problem and really really hope that i was too stupid to find the problem by myself ....
setup: windows7 / maven 3.2.3 / jdk 1.7.0_60 (64bit) / artifactory 3.5.0
Problem:
- mvn clean install deploy --> works
- mvn release:prepare --> works
- mvn release:perform fails in substep deploy (which works standalone as mentioned before)
- POM.XML and settings.xml (for testing i took the pregenerated one from artifactory) for me. but i attached them further down....
thnx in advance for ANY help!
cheers

Answer 1

I finally found a solution in a comment of a Maven Bug that had been reported for version 3.2.3.
Here's the bug: https://issues.apache.org/jira/browse/MNG-5684
The problem is the maven-source-plugin which is used to attach source jars to the project. More exactly it's the no-fork goals that cause this behavior. Using these goals the deploy plugin tries to upload the source jars twice which fails due to repository restrictions.
The solution can either be omitting the source-plugin (but then you won't have attached sources anymore) or using the forked goals (jar and test-jar) instead.
I now use the forked goals with maven 3.3.3 and I'm able to release projects again.
