Hi Todd,
I'm not sure but it's perhaps because you link the maven-assembly-plugin to
a phase.
Generally it's better to avoid this[1].
Try this instead:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptors>
<descriptor>
src/assemble/bin.xml
</descriptor>
</descriptors>
</configuration>
</plugin>
and
mvn clean package assemby:assembly
An other solution is to declare your maven-assembly-plugin configuration in
a profile.
Not sure it will resolved your problem, but you can try.
