Android 构建错误 : Program type already present: android. support.v7.app.**

Question

有很多这样的问题，但似乎没有一个能解决我的问题，所以它可能更具体到错误消息中列出的库。我已经尝试了其他答案所建议的几乎所有内容，但仍然看到相同的错误。

我也遇到了运行任务错误，但我有multiDexEnabled true。

Caused by: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

程序类型已经存在:android.support.v7.app.ActionBar$LayoutParams

Message{kind=ERROR, text=Program type already present: android.support.v7.app.ActionBar$LayoutParams, sources=[Unknown source file], tool name=Optional.of(D8)}

            details.useVersion '11.8.0'
        }
    }
}

实现项目(':libs:DobSliding')

我这里只有 1 个依赖项，所以我想知道这是否会导致冲突。

dependencies {
    implementation 'com.nineoldandroids:library:2.4.0'
}

./gradlew app:dependencies

不太确定如何解释此输出:https://gist.github.com/WrightsCS/8888da5725357d62009773cee09997f0

原来我已经将一些 .jar 文件复制到 libs 文件夹中，而 Android Studio 正在使用它们并给了我错误。一旦我删除了有问题的库，例如 AppCompat.jar 和 classes.jar，构建就很好了。

检查任何 libs 文件夹以确保您没有携带任何可能已从 IntelliJ 项目 bundle 的 android 库。
