网上下载的开源项目带C++编译库的一直报错：

A failure occurred while executing com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
   > 2 files found with path 'lib/arm64-v8a/libopencv_java3.so'.
     If you are using jniLibs and CMake IMPORTED targets, see
     https://developer.android.com/r/tools/jniLibs-vs-imported-targets

百度了很多答案五花八门的，没有一个能够解决，后来发现有一个类似的，

在app模块下面的build.gradle文件下的andriod加入下面代码，重新Sync Now，再次debug运行成功 

packagingOptions {
//下面为实际重复导致报错的so文件
    pickFirst 'lib/arm64-v8a/libc++_shared.so'
    pickFirst 'lib/arm64-v8a/libffmpeg.so'
}

sourceSets {
    main {
        jniLibs.srcDirs = ['libs']
    }
}
