Description

Multi-module project fails with NPE on assembly:assembly (assembly plugin used 2.2-beta-1; 2.2-beta-2 can not be used because of http://jira.codehaus.org/browse/MASSEMBLY-314 bug)
Command used was "mvn clean install assembly:assembly eclipse:eclipse".
Same configuration (see attached POM) works with Maven 2.0.9. Below you will find relevant excerpt from the build trace.

Note: Some internal/irrelevant information were removed from attached POM. Additionally, assembly descriptor of default assembly is attached.

Best regards,
Thorsten
