I agree. See here and vote: http://jira.codehaus.org/browse/MNG-624
-----Original Message----- From: Sean McNamara [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 11, 2006 10:20 AM To: Maven Users List Subject: RE: [m2] Using variables from parent pom.xml - like version etc. Does this really address the issue that Sanjay is trying to solve? If the parent definition requires the version to be added, then every time the version is incremented all child POMs must be updated to reflect the new parent version. This means that all POMs in the inheritance heirarchy must be updated for every version increment. I've seen some postings talking about using the release-plugin to automate this behavior (re-versioning all POMs), but haven't found any good docs on that particular plugin. Pointers would be appreciated. Seems odd that this very useful feature of M1 didn't make it into M2. --- "Brian E.
