Thank you for stepping in Russel.
Just to clarify the "unique version policy" isn't an absolute
requirement. If it's necessary multiple versions of an application or
library can be packaged (for example JUnit 3 and 4, Maven 2 and 3,
Tomcat 6&7&8, ASM 3 and 4, etc).
Thanks to your explanations it becomes clear I think that we must
package groovy 2 separately, and keep the original groovy package at
version 1.8.6 until the transition to Gradle 2 is complete.
Miguel are you ok with this plan?
