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.
