More than one file was found with OS independent path 'META-INF/INDEX.LIST'

今天項目新建了netty_lib的module，引入了多個Netty的jar包，但是編譯安裝APK時卻報錯了:More than one file was found with OS independent path 'META-INF/INDEX.LIST'. 後來發現在每個jar下都有相似的結構和文件(如下圖)

後來在網上搜索解決方案，在對應的庫的build.gradle中加入如下代碼:

android{
    ...



    packagingOptions {
        exclude 'META-INF/NOTICE' // will not include NOTICE file
        exclude 'META-INF/LICENSE' // will not include LICENSE file
        exclude 'META-INF/INDEX.LIST' // will not include INDEX.LIST file
    }
}

之後編譯，but，還是報錯。emmmm,繼續搜索解決方案，又在app.gradle中加入上述代碼，編譯還是報錯。最後又加入一句

exclude 'META-INF/*' 後成功解決了。

 

  最終解決方案：在對應的庫的build.gradle中和app.gradle 都加入如下代碼:

packagingOptions {
        exclude 'META-INF/*'
        exclude 'META-INF/NOTICE' // will not include NOTICE file
        exclude 'META-INF/LICENSE' // will not include LICENSE file
        exclude 'META-INF/INDEX.LIST' // will not include INDEX.LIST file
    }
