Question

I\'m trying to set up a Gradle build script for a new project. That project will use JPA 2 along with Querydsl.

On the following page of Querydsl\'s reference docume

Answer 1

With Gradle 1.3 and newer (older not tested) you can use Querydsl APT like this:

configurations {
  javacApt
}
dependencies {
  javacApt 'com.mysema.querydsl:querydsl-apt:3.3.0'
}
compileJava {
  options.compilerArgs <<
    '-processorpath' << (configurations.compile + configurations.javacApt).asPath <<
    '-processor' << 'com.mysema.query.apt.jpa.JPAAnnotationProcessor'
}

These compiler args are passed directly to javac.

To use with groovy compiler replace compileJava with compileGroovy.
