             Summary: Assembly fails for multi-module project if webstart-maven-plugin is in use
                 Key: MASSEMBLY-658
                 URL: https://jira.codehaus.org/browse/MASSEMBLY-658
             Project: Maven 2.x Assembly Plugin
          Issue Type: Bug
          Components: dependencySet
    Affects Versions: 2.4
         Environment: Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 13:51:

The mvn invocation I used is:
mvn clean package

I attach a simple test case of a multi-module project. If the acme-jnlp module is commented out in the parent POM then the project builds successfully. If the acme-jnlp module is not commented out, then the assembly of acme-dist fails because of a NullPointerException.

acme-dist and acme-war to not rely on the artifacts generated by acme-jnlp. The mere fact that the plugin is executed causes the later module assembly to fail.

Modules have the following purposes:
acme-parent: parent project which contains the module
acme-jnlp: create JNLP and ZIP files not used by any other modules
acme-war: create a .WAR file
acme-dist: use assembly plugin to create a .ZIP containing the .WAR
acme-deploy: holds dependencies to other modules, but does nothing else
