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.
