android - 程序类型已经存在 : gradle build error

Question

集成某些库后出现奇怪的 gradle 构建错误，之前该应用程序运行良好，但现在显示以下错误。

Program type already present: com.nostra13.universalimageloader.cache.disc.impl.ext.DiskLruCache$1
Message{kind=ERROR, text=Program type already present: com.nostra13.universalimageloader.cache.disc.impl.ext.DiskLruCache$1, sources=[Unknown source file], tool name=Optional.of(D8)}

导入以下库时开始出现此错误 --

compile("com.vdopia.ads.lw:coresdk:2.5.3.3")
    compile("com.vdopia.ads.lw:google-adapter:1.0.7")
    compile("com.vdopia.ads.lw:adcolony-adapter:1.0.5")
    compile("com.vdopia.ads.lw:applovin-adapter:1.0.5")
    compile("com.vdopia.ads.lw:baidu-adapter:1.0.5")
    compile("com.vdopia.ads.lw:chartboost-adapter:1.0.7")
    compile("com.vdopia.ads.lw:facebook-adapter:1.0.5")
    compile('com.devbrackets.android:exomedia:4.0.3') //{
    //If you use your own version of exoplayer, uncomment below
    // exclude group: 'com.google.android.exoplayer'
    // }
    /*
     * Note: If you use the Baidu adapter, then please include:
     */
    compile ("com.android.support:palette-v7:27.1.1")
    compile("com.vdopia.ads.lw:inmobi-adapter:1.0.5")

您的多个依赖项具有共享相同路径和名称的类。弄清楚它到底是那些依赖项中的哪一个，并使用 exclude group 来省略它，例如

compile("com.vdopia.ads.lw:coresdk:2.5.3.3") { exclude group: 'com.nostra13.universalimageloader' }
