I forked spring-social and added a good amount of new methods to LinkedInTemplate

I've been trying to assemble and install (gradle assemble install) my changes to my local m2 repo but my end result are always one jar per module, I haven't been able to assemble the whole project in one big jar, e.g. I've got a spring-social-core-1.0.0.BUILD-SNAPSHOT.jar with just the code for the "core" module, the same goes for "facebook", etc

I even tried to assemble it using
Code:
./gradlew spring-social:assemble
but got this
Code:
FAILURE: Could not determine which tasks to execute.

* What went wrong:
Project 'spring-social' is ambiguous in root project 'spring-social'. Candidates are: 'spring-social-connect', 'spring-social-connect-web', 'spring-social-core', 'spring-social-facebook', 'spring-social-linkedin', 'spring-social-oauth', 'spring-social-tripit', 'spring-social-twitter'.

* Try:
Run gradlew tasks to get a list of available tasks.

BUILD FAILED
What's the trick to have this assembled in just one jar?
What I'm doing wrong?

Thanks
