Android Studio/Gradle项目清理和构建，但调试失败

我刚刚将一个android项目从IntelliJ/Maven安装迁移到android Studio/Gradle安装。我可以清理它并构建它，但是当我尝试调试它时，我得到了以下错误。我在这里和其他地方看到了一些答案，似乎这个问题可能是由各种各样的问题引起的。我是一个Gradle初学者，但我相信我已经排除了其中的一些，例如重复依赖和突破65K方法限制（我的项目还没有那么大，我没有引用那么多/大型库）。如果有人能给我指出正确的方向，我将不胜感激

注意：我也不知道lib目录中有2个jar文件

主要问题是这条线

多个dex文件定义BuildConfig

首先尝试从上述位置或

libs

文件夹中删除AppCompatLibrary

---

出现此错误的原因是，在单个项目依赖项中存在两个相同的库。

我发现了问题。libs目录中的一个文件应该打包为“aar”而不是“jar”文件，因为它是一个Android库。我这样做了，并添加了行

compile'ke.co.hoji:file name:1。0@aar“

添加到生成文件中，这就解决了问题
