Android gradle build提供DuplicateFileException

Question

嗨，在添加apache poi gradle构建之后，我得到了这个期望。你能给我解释一下怎么解决吗。

我尝试过以多种方式排除套餐选项，但都没有成功

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.1.0'
    compile 'com.android.support:cardview-v7:25.1.0'
    compile 'org.greenrobot:greendao:3.2.0'
    compile group: 'org.apache.poi', name: 'poi-ooxml', version: '3.9'

}

错误：任务'： app： transformResourcesSusMergeJavaResForDebug'执行失败。

Answer 1

通过将此文件添加到渐变文件来排除重复的文件

    android {
        ...
        packagingOptions {
                exclude 'META-INF/DEPENDENCIES'
                exclude 'META-INF/NOTICE'
                exclude 'META-INF/LICENSE'
                exclude 'META-INF/LICENSE.txt'
                exclude 'META-INF/NOTICE.txt'
            }
}

Answer 2

转到您的构建。渐变文件并添加以下行：

 packagingOptions {
    exclude 'META-INF/LICENSE.txt'
  }

在我的情况下，我不得不添加如下内容：

apply plugin: 'com.android.library'    
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
}
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.google.android.gms:play-services:6.5.87'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.mcxiaoke.volley:library:1.0.15'
    compile 'com.google.code.gson:gson:2.2.4'
    compile "org.apache.httpcomponents:httpcore:4.4.1"
    compile "org.apache.httpcomponents:httpmime:4.3.6"


}

尝试使用以下代码排除重复的文件

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    pickFirst  'META-INF/license.txt'
        }
