h1. Groovy Add-on

The Groovy Add-on allows to use the "Groovy language":http://groovy.codehaus.org/ within z2 applications. One can use pure Groovy modules beside pure Java modules as well as modules containing both Java and Groovy source code. The latter case requires a three pass compilation (called "joint compilation mode") while in the first case all modules (Java and Groovy) are compiled within one single pass. 

The z2-Groovy compiler wrapper checks for each source component (i.e. @java/src.api@ and @java/src.impl@) whether it contains pure Groovy source files or Java and Groovy sources and chooses the appropriate compiler.
