Gradle : Unable to generate QueryDSL classes

问题

Gradle version: 5.1

Java version: 11

I have the following task defined in gradle file to generate QueryDSL classes:

task generateQClasses (type: JavaCompile) {
    source = sourceSets.main.java.srcDirs
    classpath = sourceSets.main.compileClasspath
    destinationDir = file('src/main/java')
    options.annotationProcessorPath = configurations.annotationProcessor
    options.compilerArgs = ['-proc:only', '-processor', 'com.querydsl.apt.jpa.JPAAnnotationProcessor', '-Aquerydsl.packageSuffix=.querydsl']
}

Below is my dependencies block:

annotationProcessor "com.querydsl:querydsl-apt:4.2.1:jpa"
annotationProcessor "org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.2.Final"
annotationProcessor "javax.annotation:javax.annotation-api:1.3.2"

If I execute `gradlew generateQClasses, I see the following in the logs:

Attempt to recreate a file for type foo.bar.QClass
error: Attempt to recreate a file for type foo.bar.QClass

It fails with error saying the file already exists. How can I configure this task to overwrite the files if they exist?

Also, the above config is the config for the root project and it has 5 subprojects. AnnotationProcessor is able to overwrite the files in one of the sub project but not the others (all the subprojects have the same config). Am I missing anything?
