This plugin does a few things to make it easier/safer to use Java annotation processors in a Gradle build:

* it ensures the presence of configurations for your compile-time only dependencies (annotations, generally) and annotation processors, consistently across all supported Gradle versions; * automatically configures the corresponding JavaCompile and GroovyCompile tasks to make use of these configurations, when the java or groovy plugin is applied; * automatically configures IntelliJ IDEA and/or Eclipse when the net.ltgt.apt-idea or net.ltgt.apt-eclipse plugins are applied.
