[jira] Created: (MNG-1527) NPE in groupID-less POMs
NPE in groupID-less POMs
------------------------
Key: MNG-1527
URL: http://jira.codehaus.org/browse/MNG-1527
Project: Maven 2
Type: Bug
Components: maven-artifact
Versions: 2.0
Environment: JDK 1.5.0_05, Kubunto Linux 5.1
Reporter: Arik Kfir
I have a parent POM which defines a group ID and is parsed+deployed OK.
I also have a child POM which extends the parent POM. When running the following on the child POM, I get:
arik@corleon:~/projects/corleon-site/trunk$ mvn release:prepare -Dusername=arikkfir

When I add the groupId to the child POM it works ok.
Seems to me that the group ID should be inherited from the parent POM as well, no?

[jira] Commented: (MNG-1527) NPE in groupID-less POMs
Posted by "mike perham (JIRA)" <ji...@codehaus.org>.
[ http://jira.codehaus.org/browse/MNG-1527?page=comments#action_52534 ]
mike perham commented on MNG-1527:
----------------------------------
We are seeing this issue also in reactor builds. When building the project itself, the groupId is inherited correctly. But when referencing that project from another, the groupId is not picked up out of the installed POM. The installed POM does not have the groupId set in it so that project's transitive deps fail to resolve.
