I don't know if this is the answer or not but it might lead you in the right direction...
The command install:install
is actually a goal on the maven-install-plugin. This is different than the install
maven lifecycle phase.
Maven lifecycle phases are steps in a build which certain plugins can bind themselves to. Many different goals from different plugins may execute when you invoke a single lifecycle phase.
What this boils down to is the command...
mvn clean install
is different from...
mvn clean install:install
The former will run all goals in every cycle leading up to and including the install (like compile, package, test, etc.). The latter will not even compile or package your code, it will just run that one goal. This kinda makes sense, looking at the exception; it talks about:
StarTeamCollisionUtil: The packaging for this project did not assign a file to the build artifact
Try the former and your error might just go away!
