Problem with generating Querydsl classes with Gradle

Viewed 4692

I want to generate 'Q' classes using querydsl. The problem that I'm facing is described by errors:

> Task :compileJava FAILED 
Attempt to recreate a file for type com.my.dinner.rest.database.entity.QIngredientAmount
Attempt to recreate a file for type com.my.dinner.rest.database.entity.QUser

error: Attempt to recreate a file for type com.my.dinner.rest.database.entity.QIngredient
error: Attempt to recreate a file for type com.my.dinner.rest.database.entity.QRecipe
5 errors

Files are generated but build is failing, I suppose that classes are generated multiple times but I don't know how to fix it. I was using tips described here:

https://youtrack.jetbrains.com/issue/IDEA-212487?_ga=2.72682843.91471992.1592753352-1655482529.1589711163#focus=streamItem-27-3491579.0-0

but it does not work in my case.

I've tried every build.gradle configuration that I have found in Google, Github but nothing helped.

My build.gradle file:

So i solved it randomly changing build.gradle file.

I deleted unnecessary plugins and a whole section below dependecies and it generated all classes in:

build/generated/annotationProcessor/java/main

My updated build.gradle file:

plugins {
    id 'groovy'
    id 'java'
}

sourceCompatibility = '11'
group 'com.my.dinner.rest'
version '1.0-SNAPSHOT'

def springBootVersion = '2.3.1.RELEASE'
def springFrameworkVersion = '5.2.7.RELEASE'
def lombokVersion = '1.18.12'
def querydslVersion = '4.3.1'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.codehaus.groovy', name: 'groovy-all', version: '3.0.4', ext: 'pom'

    // Spring
    compile group: 'org.springframework', name: 'spring', version: springFrameworkVersion, ext: 'pom'
    compile group: 'org.springframework', name: 'spring-webmvc', version: springFrameworkVersion

    compile group: 'org.springframework.boot', name: 'spring-boot', version: springBootVersion
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: springBootVersion
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-logging', version: springBootVersion
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: springBootVersion

    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.4.17.Final'

    // Querydsl
    implementation group: 'com.querydsl', name: 'querydsl-jpa', version: querydslVersion
    implementation group: 'com.querydsl', name: 'querydsl-apt', version: querydslVersion
    implementation group: 'com.querydsl', name: 'querydsl-core', version: querydslVersion

    compile group: 'com.typesafe', name: 'config', version: '1.4.0'
    compile group: 'org.modelmapper', name: 'modelmapper', version: '2.3.8'

    annotationProcessor group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: springBootVersion

    annotationProcessor group: 'com.querydsl', name: 'querydsl-apt', version: querydslVersion
    annotationProcessor group: 'com.querydsl', 'name': 'querydsl-apt', version: querydslVersion, classifier: 'jpa'

    testCompile group: 'org.springframework.boot', name: 'spring-boot-starter-test', version: springBootVersion
    testCompile group: 'junit', name: 'junit', version: '4.13'
    testCompile group: 'com.h2database', name: 'h2', version: '1.4.200'
}

Versions:

  • Java: 11.0.7
  • Gradle: 6.5
  • Intellij: 2020.1.1
  • Ubuntu: 20.04 LTS

So I think that all questions about this problem that I have looked before were bound with older gradle versions, and there were many workarounds that don't need to be applied in my version of gradle.
