Subject [jira] Commented: (MRELEASE-273) Regression: NullPointerException at end of standalone "release:perform"
Date Fri, 10 Oct 2008 18:31:51 GMT

    [ http://jira.codehaus.org/browse/MRELEASE-273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=150508#action_150508
] 

Kevin Nardi commented on MRELEASE-273:
--------------------------------------

This is very annoying, as it causes our build system to appear to fail every time, and we
have to check the log to see if it really succeeded or not. Can this please be fixed?

> 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.
