Android 错误：任务'；的执行失败：应用程序：transformResourcesWithMergeJavaResForDebug'；

因此，在尝试运行我的项目时，我不断收到一个gradle构建错误。我已经寻找了其他解决方案，有些人说：

packagingOptions {
    exclude 'META-INF/NOTICE'
}

我的应用程序的gradle.build可以解决这个问题，但是它不能。下面是我的应用程序的gradle.build当前的外观

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.google.android.gms:play-services:8.3.0'
    compile 'com.google.android.gms:play-services-ads:8.3.0'
    compile 'com.google.android.gms:play-services-identity:8.3.0'
    compile 'com.firebase:firebase-client-android:2.3.1'
}

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.example.j.airportmeet"
        minSdkVersion 18
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

    packagingOptions {
        exclude 'META-INF/NOTICE'
    }

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

编辑 完全错误如下：

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

错误消息表明，您没有排除存在于多个依赖项中的

META-INF/LICENSE

文件

com.android.build.api.transform.TransformException:com.android.builder.packaging.DuplicateFileException:APK META-INF/LICENSE中复制的重复文件

---

在我的例子中，我有两个对同一个library.jar的引用，只删除了其中一个，瞧，它现在正在编译，正在工作

---

我也面临同样的问题。在我的例子中，通过将下面的代码添加到build.gradle（Module:app）中，在

android{…}

标记中，解决了这个问题

packagingOptions {
    exclude 'META-INF/NOTICE' // will not include NOTICE file
    exclude 'META-INF/LICENSE' // will not include LICENSE file
    // as noted by @Vishnuvathsan you may also need to include
    // variations on the file name. It depends on your dependencies.
    // Some other common variations on notice and license file names
    exclude 'META-INF/notice'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license'
    exclude 'META-INF/license.txt'
}

---

排除“META-INF/notice.txt”排除“META-INF/license.txt”这对我不起作用，所以我只是删除了我的上一个依赖项，它就起作用了。这个错误只在我升级到Android Studio 2.2.2（从2.1.1）后发生。2.2.2强制升级到Gradle，然后开始出现此错误。添加排除项可以修复它。谢谢，这对我没用。但我真的需要谷歌云api的依赖性。我如何解决这个问题？
