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

To use the JPA Metamodel Generator with Gradle I'm successfully using the following in my build.gradle and it works like a charm:

buildscript {
    ext {}
    repositories { // maven central & plugins.gradle.org/m2 }
    dependencies {
        // other dependencies, e.g. Spring
        classpath('gradle.plugin.at.comm_unity.gradle.plugins:jpamodelgen-plugin:1.1.1')
    }

    apply plugin: 'at.comm_unity.gradle.plugins.jpamodelgen'

    dependencies {
        compile('org.hibernate:hibernate-jpamodelgen:5.1.0.Final')
    }

    jpaModelgen {
        jpaModelgenSourcesDir = "src/main/java"
    }

    compileJava.options.compilerArgs += ["-proc:none"]
}

Within the build task, the static metamodel classes suffixed with '_' are generated. Afterwards they are located in the same directory as my @Entity models are.
