Maven+；android R.java和BuildConfig.java重复类

我在互联网上搜索解决方案，做了上面提到的所有事情，但没有解决我的问题

这是我的pom.xml

删除此行：

<source>gen</source> 

gen

这通常发生在两个构建系统在同一代码库上工作时，为生成的代码配置了不同的位置（例如，Eclipse、Maven等）。在这种情况下，将在两个不同的位置创建这些生成的类。在我的例子中，这些文件位于

\gen

和

\target\generated sources\r

目录下。因此，在构建之前清理“gen”和“target”有助于解决这个重复类的问题
