-----------------------------------------------
Key: MOJO-1735
URL: https://jira.codehaus.org/browse/MOJO-1735
Project: Mojo
Issue Type: New Feature
Components: _Mojo Parent
Reporter: Marcel Overdijk
When adding a repository to maven plugin pom, like
<repositories>
<repository>
<id>com.asual.maven.public</id>
<name>Asual Public Repository</name>
<url>http://www.asual.com/maven/content/groups/public</url>
</repository>
</repositories>
and having sandbox as parent
<parent>
<groupId>org.codehaus.mojo</groupId>
<artifactId>mojo-sandbox-parent</artifactId>
<version>9</version>
</parent>
causes mvn install to throw a NPE:
[ERROR] Failed to execute goal

On the discussion forum it was mentioned it's not allowed to repo's:
https://fisheye.codehaus.org/browse/mojo/trunk/mojo/mojo-parent/pom.xml?hb=true#to323
After removing the repo mvn install works flawlessly.
However the NPE makes it difficult to find out why mvn install was failing.
