mysema.querydsl gradle

build.gradle

sourceSets {
    generated {
        java {
            srcDirs = ['src/main/generated']
        }
    }
}

configurations {
    querydslapt
}

dependencies {
    compile 'org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final'
    compile "com.mysema.querydsl:querydsl-jpa:$querydslVersion"
    querydslapt "com.mysema.querydsl:querydsl-apt:$querydslVersion"
}

task generateQueryDSL(type: JavaCompile, group: 'build', description: 'Generates the QueryDSL query types') {
    source = sourceSets.main.java
    classpath = configurations.compile + configurations.querydslapt
    options.compilerArgs = [
            "-proc:only",
            "-processor", "com.mysema.query.apt.jpa.JPAAnnotationProcessor"
    ]
    destinationDir = sourceSets.generated.java.srcDirs.iterator().next()
}

compileJava {
    dependsOn generateQueryDSL
    source generateQueryDSL.destinationDir
}

compileGeneratedJava {
    dependsOn generateQueryDSL
    options.warnings = false
    classpath += sourceSets.main.runtimeClasspath
}

clean {
    delete sourceSets.generated.java.srcDirs
}

idea {
    module {
        sourceDirs += file('src/main/generated')
    }
}

How can I configure this for groovy based project?

I tried changing as following but MetaModels are not being generated for Entity class but empty directory structure is created.

task generateQueryDSL(type: GroovyCompile, group: 'build', description: 'Generates the QueryDSL query types') {
    source = sourceSets.main.groovy
    classpath = configurations.compile + configurations.querydslapt
    options.compilerArgs = [
            "-proc:only",
            "-processor", "com.mysema.query.apt.jpa.JPAAnnotationProcessor"
    ]
    destinationDir = sourceSets.generated.java.srcDirs.iterator().next()
}```

It would be too different to configure the task generateQueryDSL for MongoDB?

thx a lot!! very useful infomation
