错误：任务执行失败＆＃39;：app：transformResourcesWithMergeJavaResForDebug＆＃39;

Question

因此，我在尝试运行项目时不断收到gradle构建错误。我搜索了其他解决方案，有人说添加：

packagingOptions {
    exclude 'META-INF/NOTICE'
}

到我的应用程序的gradle.build会解决问题，但是，它没有。这是我的应用程序的gradle.build目前的样子。

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'
        }
    }
}

修改

完整的错误是：

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

Answer 1

由于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：在APK META-INF / LICENSE中复制的重复文件

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'
}

Answer 2

在我的情况下，我有两个对同一个库.jar的引用，只删除其中一个并且vo，它现在正在编译，它正在工作。

Answer 3

我遇到了同样的问题。在我的例子中，通过将以下代码添加到build.gradle（Module：app），在android{...}标记内，解决了问题

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'
}
