Description
When starting Roo shell with a multi module project where the <version /> is specified only in the parent pom, a NullPointerException is thrown at startup. Roo should support projects where the <version /> is only specified in the parent pom.
The obvious workaround is to specify <version /> in each module.
Here is the output of the Roo shell startup :

See https://jira.springsource.org/browse/ROO-1193#comment-84782. Same error in 1.2.3 SNAPSHOT, and similar fix for that JIRA entry (groupId only in parent pom). I couldn't add an issue link from either the source or target issue.

I'm using Roo 1.2.2 and I don't get a NPE, but Roo reports an error and refuses to go on:
