Automatically Add built source files in STS 4?

Question

Currently I'm stuck with automatically added built source files after compiled.

QueryDSL IS WORKING (automatically added after refresh.). However, MapStruct is not working.

QueryDSL Output is src/main/generated/querydsl, each of projects. MapStruct is default (build/generated/sources/annotationProcessor/java/main) on their projects.

After add source files manually, this code is works, But I want to add source automatically like querydsl.

here is my part of build.gradle.

// Root build.gradle

buildscript {
    ext {
        springBootVersion = '2.7.2'
        dependencyManagementVersion = '1.0.12.RELEASE'
        mysqlVersion = '8.0.30'
        lombokVersion = '6.5.0.3'
        queryDslVersion = '4.4.0'
        queryDslPluginVersion = '1.0.10'
        mapStructVersion = '1.5.3.Final'
        lombokMapstructBindingVersion = "0.2.0"
    }
    repositories {
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
        classpath "io.spring.gradle:dependency-management-plugin:${dependencyManagementVersion}"
        classpath "io.freefair.gradle:lombok-plugin:${lombokVersion}"
        // for QueryDSL
        classpath "gradle.plugin.com.ewerk.gradle.plugins:querydsl-plugin:${queryDslPluginVersion}"
    }
}

subprojects {
    group = 'test.test'
    version '0.0.1-SNAPSHOT'

    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'io.freefair.lombok'
    apply plugin: 'com.ewerk.gradle.plugins.querydsl'
    
    sourceCompatibility = '11'

    repositories {
        mavenCentral()
    }

    dependencies {
      compile group: 'com.querydsl', name: 'querydsl-jpa'
      annotationProcessor group: 'com.querydsl', name: 'querydsl-apt'

        // for QueryDSL
        // implementation "com.querydsl:querydsl-core:${queryDslVersion}"
        // implementation "com.querydsl:querydsl-jpa:${queryDslVersion}"
        // annotationProcessor "com.querydsl:querydsl-apt:${queryDslVersion}:jpa"

        annotationProcessor "org.projectlombok:lombok-mapstruct-binding:${lombokMapstructBindingVersion}"
        
        testImplementation 'junit:junit:4.12'
    }
}

// for QueryDSL
task cleanGeneatedDir(type: Delete) {
    delete file('src/main/generated')
}

// A Project build.gradle

    implementation group: 'org.springframework.boot', name: 'spring-boot-starter-web'

}

def querydslDir = "src/main/generated/querydsl"

querydsl {
    library = "com.querydsl:querydsl-apt"
    jpa = true
    querydslSourcesDir = querydslDir
}
sourceSets {
    main.java.srcDir querydslDir
}
compileQuerydsl{
    options.annotationProcessorPath = configurations.querydsl
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
    querydsl.extendsFrom compileClasspath
}

Answer 1

It automatically configured by sourceSets > main > java > srcDirs in gradle.

in codes,

sourceSets {
    main {
        java {
            srcDirs = ['src/main/java', 'build/generated/sources/annotationProcessor/java/main']
        }
    }
}
