android異常 More than one file was found with OS independent path 'META-INF/XXX'

android 異常總結：一個文件在jar包中出現多次。

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

> More than one file was found with OS independent path 'META-INFXXX'

需要在app.gradle文件里面android節點下添加這樣的代碼

   packagingOptions {
        exclude 'META-INF/XXX'
   exclude 'META-INF/XXX'
   exclude 'META-INF/XXX'
   exclude 'META-INF/XXX'
    }

具體的修改位置

apply plugin: '

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId ""
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    packagingOptions {
        exclude 'META-INF/XXXX'
    }


    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
