android - 为什么在我的 android 项目中生成 3 个构建文件夹？

Question

每次我进行任何更改并运行应用程序时，都会在我的项目中创建 3 个构建文件夹，这会出现“我的项目中有 3 个 BuildConfig 文件”之类的错误

当我清理项目并重建它时，该应用程序成功运行但再次创建。

这是我的项目结构：

项目构建.gradle

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext{
        kotlin_version = "1.3.72"
        ext.archLifecycleVersion = '2.2.0'
        ext.room_version = '2.1.0-alpha01'
        ext.navigation_version = '1.0.0-alpha06'
        ext.kodein_version = '5.2.0'
    }

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {

        maven {

        }
    }

    buildFeatures {
        dataBinding = true
        viewBinding = true
    }
}

}

更新：

我尝试了这个->“文件->使用 Gradle 文件同步项目”并手动删除了“build 2”和“build 3”文件夹，它没有再次生成，但一段时间后仍然面临同样的问题。一天后我运行了我的应用程序，并且显示了此错误。我将清理项目并重建，然后它将运行。但是每次都有一个“被多次定义”的新文件，正如它在错误中所说的那样。我仍然无法找到发生这种情况的确切原因。
