[jira] [Commented] (ARCHETYPE-531) NullPointerException when module
not specified or config empty in EAR plugin
[ https://issues.apache.org/jira/browse/ARCHETYPE-531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16719166#comment-16719166 ]
Marco Rothe commented on ARCHETYPE-531:
---------------------------------------
I encountered the same problem today: The missing 'modules' tag in a pluginManagment section causes a nullpointer. :(
Is there any (planned) progress on this bug?

> In same file on line 303, I believe catching any Exception and rethrowing a MojoFailureException is not really helpful to anyone since it hides the actual cause and you have to dig deep into the code to find it. At least it should be made more verbose. This is what is being thrown:
