Regression: NullPointerException at end of standalone "release:perform"
-----------------------------------------------------------------------
Key: MRELEASE-273
URL: http://jira.codehaus.org/browse/MRELEASE-273
Project: Maven 2.x Release Plugin
Issue Type: Bug
Affects Versions: 2.0-beta-6
Environment: Maven 2.0.7, maven-release-plugin 2.0-alpha-6
Reporter: Max Bowsher
Priority: Blocker
I executed "mvn release:perform -DconnectionUrl=scm:svn:......". The actual
performing succeeded, but then the plugin failed with a NullPointerException -
it seems that the plugin attempts to unconditionally run code analogous to "mvn
release:clean", but this is inappropriate because release:perform is not
supposed to require a project to be able to run.
Output:
