Android Gradle在APK META-INF/license.txt中复制的重复文件

Question

我将在我的Android应用程序中添加Spring的RESTful Web Service支持,如https://spring.io/guides/gs/consuming-rest-android/所述.

这是顶级的build.gradle配置:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

这是我的app/build.gradle配置:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.example"
        minSdkVersion 8
        targetSdkVersion 17
    }

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

    dependencies {
        compile 'com.android.support:appcompat-v7:+'
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
        compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
    }

    packagingOptions {
        exclude 'META-INF/NOTICE' // will not include NOTICE file
        exclude 'META-INF/LICENSE' // will not include LICENSE file
    }

}

现在它失败并出现以下错误:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/license.txt

我做错了什么以及如何解决？

Answer 1

在应用程序级别gradle文件中写下以下行

android {
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }
}

Answer 2

如果所选答案中的解决方案无法解决您的问题,请尝试添加

    exclude 'META-INF/ASL2.0'

同样.或者基本上,识别重复文件的名称并将其排除.上面的补充为我解决了这个问题.

Answer 3

它对我有帮助。试试这个代码:)

packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}
