Hi,
I am upgrading my projects from maven 2 to maven 3 and most of them are
fine. However, there is one project that gives a NullPointerException during
the assembly:
maven builder waiting
mavenExecutionResult exceptions not empty
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute
goal org.apache.maven.plugins:maven-assembly-plugin:2.2:single (make
zipfile) on project plugin-sdk-assembly: Execution make zipfile of goal
org.apache.maven.plugins:maven-assembly-plugin:2.2:single failed.

Any idea what might be wrong ?
