Java 使用Gradle生成Querydsl类时出现问题

我想使用querydsl生成“Q”类。我所面临的问题由错误描述：

> 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

文件被生成，但构建失败，我想类被生成多次，但我不知道如何修复它。 我使用的技巧如下所述：

但这在我的情况下不起作用

因此，我认为我之前研究过的关于这个问题的所有问题都与较旧的gradle版本有关，并且有许多变通方法不需要在我的gradle版本中应用。

compileOnly{ExtendFrom annotationProcessor}为什么？当您在annotationProcessor配置中有库时，querydsl插件可能与较新版本的Gradle运行处理器本身的方式不兼容？请检查生成类的位置。我怀疑当生成类和普通类编译的输出路径混乱时，可能会发生错误。例如，querydsl.ExtendFrom compileClasspath-不确定，但它可能会更改输出路径。Gradle用于生成的类，您可以根据自己的配置进行更改。
