【问题描述】：
我想使用 querydsl 生成“Q”类。我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
Attempt to recreate a file for type com.my.dinner.rest.database.entity.QRating

error: Attempt to recreate a file for type

5 errors
文件已生成但构建失败，我想类已生成多次但我不知道如何修复它。 我正在使用此处描述的提示：
但在我的情况下它不起作用。
我已经尝试了在 Google、Github 中找到的所有 build.gradle 配置，但没有任何帮助。

【问题讨论】：
-
compileOnly { extendsFrom annotationProcessor } 为什么？
-
当您在 annotationProcessor 配置中有库时，可能 querydsl 插件与较新版本的 Gradle 运行处理器本身的方式不兼容？
-
检查生成类的位置。我怀疑当生成的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.extendsFrom compileClasspath- 不确定，但它可能会改变输出路径。 Gradle 使用separate output directory 生成类，您可以通过配置更改它。
