Q classes not generated with Java 21

[onacit]

No classes generated with Java21

With following dependencies, with Spring Boot 3.1.7.

+--- com.querydsl:querydsl-apt:5.0.0
|    \--- com.querydsl:querydsl-codegen:5.0.0
|         +--- com.querydsl:querydsl-core:5.0.0
|         |    \--- com.mysema.commons:mysema-commons-lang:0.2.4
|         +--- com.querydsl:codegen-utils:5.0.0
|         |    +--- org.eclipse.jdt:ecj:3.26.0
|         |    \--- io.github.classgraph:classgraph:4.8.108
|         +--- javax.inject:javax.inject:1
|         \--- io.github.classgraph:classgraph:4.8.108

java {
    sourceCompatibility = '17'
//    sourceCompatibility = '21'
}
dependencies {
    annotationProcessor "com.querydsl:querydsl-apt:${dependencyManagement.importedProperties['querydsl.version']}:jakarta"
    implementation "com.querydsl:querydsl-jpa:${dependencyManagement.importedProperties['querydsl.version']}:jakarta"
    annotationProcessor "jakarta.persistence:jakarta.persistence-api" // 이게 없으면 compile-time error
}

Q classes are generated along with JPA static metamodels

$ JAVA_HOME=$JAVA_HOME17 javac --version
javac 17.0.9
$ JAVA_HOME=$JAVA_HOME17 clean build

But following configuration and command does not generate Q classes, but only JPA static metamodels.

java {
//    sourceCompatibility = '17'
    sourceCompatibility = '21'
}

$ JAVA_HOME=$JAVA_HOME21 javac --version
javac 21.0.1
$ JAVA_HOME=$JAVA_HOME21 clean build

Add <classifier>jakarta</classifier> to your querydsl dependencies in pom.

@temanskyM I don't use Maven, and I did use jakarta classifiers as you can see.

@temanskyM

	implementation 'com.querydsl:querydsl-core:5.0.0'
	implementation 'com.querydsl:querydsl-jpa:5.0.0:jakarta'
	annotationProcessor(
			"jakarta.persistence:jakarta.persistence-api",
			"jakarta.annotation:jakarta.annotation-api",
			"com.querydsl:querydsl-apt:5.0.0:jakarta")

like this? but still not work for me.

@MarkJeong1 @onacit try to use my fork instead.

Just change group id to io.github.openfeign.querydsl, version to 6.0.0.M3 and drop jakarta classifier.

It should work, as Java 21 is part of the build on my fork
https://github.com/OpenFeign/querydsl

But, please let me know if it doesn't, I'm more than happy to fix it.

[celcius112]

For those trying to use OpenFeign's fork with Gradle, these are the necessary dependencies:

  val queryDslVersion = "6.0"
  implementation("io.github.openfeign.querydsl:querydsl-core:$queryDslVersion")
  implementation("io.github.openfeign.querydsl:querydsl-jpa:$queryDslVersion")
  annotationProcessor("io.github.openfeign.querydsl:querydsl-apt:$queryDslVersion:jpa")
  annotationProcessor("jakarta.persistence:jakarta.persistence-api")
  annotationProcessor("jakarta.annotation:jakarta.annotation-api")

@celcius112 I'm starting to make a Gradle plugin for querydsl, if you keen to alpha test it, let me know

[celcius112]

@velo why not :) feel free to ping me on the related "issue" if you require my help
