How to querydsl with spring-data-mongodb and gradle

[viktorgt]

I'm unable to configure gradle to generate the query types for Querydsl. Following advices like #2444, my configuration looks as follows:

plugins {
	id 'org.springframework.boot' version '2.3.1.RELEASE'
	id 'io.spring.dependency-management' version '1.0.9.RELEASE'
	id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
	implementation 'org.springframework.boot:spring-boot-starter-web'

	compile 'com.querydsl:querydsl-mongodb:4.3.1'
	annotationProcessor 'com.querydsl:querydsl-apt:4.3.1:morphia'
	annotationProcessor 'org.springframework.boot:spring-boot-starter-data-mongodb'
}

The query types are not generated.
Gradle version: 6.4.1

Unfortunately, the documentation provides only a configuration for maven and all other guides on the web seem to be deprecated.

Hi @viktorgt please try this, I'm able to generate the Q-Classes with this.. hope it helps you and its also running for me.. Note I'm not using the Morphia annotations and the dependency, instead i'm using @com.querydsl.core.annotations.QueryEntity and as for your build.gradle

configurations {
	compileOnly {
		extendsFrom annotationProcessor
	}
}

dependencies {
   //your general spring data and other spring dependencies
   compileOnly 'com.querydsl:querydsl-apt'
   compile 'com.querydsl:querydsl-mongodb:4.3.1'
   compile 'com.querydsl:querydsl-core'

   annotationProcessor ('com.querydsl:querydsl-apt:4.3.1:general', 'javax.annotation:javax.annotation-api')
}

//Your path can be as per your choice of source directory for the Q-Classes mine is /src/main/generated/

def queryDslOutput = file(new File(projectDir, '/src/main/generated/'))
sourceSets {
    generated {
        java {
            srcDir queryDslOutput
        }
    }
}

compileJava {
	options.compilerArgs << '-s'
	options.compilerArgs << "$projectDir/src/main/generated/"
	
	doFirst {
		file(new File(projectDir, '/src/main/generated/')).mkdirs();
	}
}

Edit: I'm also not using the JPA Annotations or the Spring-Data-JPA
Gradle Version: 6.5

P.S: I've edited this comment a lot of times, because I'm new to Github.

@somudas93 thank you. This one actually works 👍

We could also add delete(files("${projectDir}/src/main/generated/")) in the doFirst part of the compileJava, so old files will be overridden, when there are changes.
