解决jar包里面的文件冲突

Error:Execution failed for task ':zhifubao:transformResourcesWithMergeJavaResForDebug'.

> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties

File1: C:\Users\hui\.gradle\caches\modules-2\files-2.1\io.reactivex.rxjava2\rxjava\2.0.1\57f850a6b317e5582f1dbaff10a9e7d7e1fcdcfb\rxjava-2.0.1.jar

在build.gradle里面添加

android {
    packagingOptions {
        exclude 'META-INF/rxjava.properties'
    }
}

'META-INF/rxjava.properties'其实是上面红色部分
