NullPointer excecption on assembly plugin

[Jose Alberto Fernandez <jo...@cellectivity.com>]

We are getting the following stack-trace while executing the
assembly:directory goal.

The artifact com.cellectivity:fattoush-test-shared is declared on the module
POMs as:

    <dependency>
      <groupId>com.cellectivity</groupId>
      <artifactId>fattoush-test-shared</artifactId>
      <scope>test</scope>
      <version>[1.0,)</version>
      <type>test-jar</type>
    </dependency>

As it is needed only for testing. Notice that the version is required by MVN
and if I ask for the specific current version ${project.version} MVN
complaints it cannot find it. Eventhough it is one of the artifacts that is
building.

when we execute mvn install everything works, but if we do mvn install
assembly:directory it fails during assembly. the stack-trace is as follows:

The interesting part of the assembly descriptor is:

  <moduleSets>
    <moduleSet>
      <includes>
        <include>com.cellectivity:fattoush-app-portal</include>
      </includes>
      <binaries>
        <outputDirectory>${version}/lib</outputDirectory>
        <includeDependencies>true</includeDependencies>
        <unpack>false</unpack>
      </binaries>
    </moduleSet>
  </moduleSets>

Funny enough the error only happens consistently on certain machines and not
in others. I am able to build, but one of my co-workers cannot, same branch.
So much about reproducible builds.

Any clues on what can be going wrong, will be appreciated.
