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

Question

我将向我的 Android 应用程序添加 Spring 的 RESTful Web 服务支持，如https://spring.io/guides/gs/consuming-rest-android/ 所述。

这是* 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

在您的应用级 gradle 文件中写入以下行

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不能解决您的问题，请尝试添加

    exclude 'META-INF/ASL2.0'

也是。或者基本上，确定重复文件的名称并将其排除。上面的添加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'
}

Answer 4

添加这些行对我有帮助。

shadowJar {
    // Filtering shadow jar contents by file pattern.
    exclude 'schemaorg_apache_xmlbeans/attribute/**'
    exclude 'schemaorg_apache_xmlbeans/attributegroup/**'
    exclude 'schemaorg_apache_xmlbeans/element/**'
    exclude 'schemaorg_apache_xmlbeans/identityconstraint/**'
    exclude 'schemaorg_apache_xmlbeans/javaname/**'
    exclude 'schemaorg_apache_xmlbeans/modelgroup/**'
    exclude 'schemaorg_apache_xmlbeans/namespace/**'
    exclude 'schemaorg_apache_xmlbeans/src/**'
    exclude 'schemaorg_apache_xmlbeans/system/sXML*/**'
    exclude 'schemaorg_apache_xmlbeans/system/s8C3F193EE11A2F798ACF65489B9E6078/**'
    exclude 'schemaorg_apache_xmlbeans/type/**'

    exclude 'repackage/**'

    exclude 'LICENSE.txt'
    exclude 'NOTICE.txt'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/maven/**'

    // these are only needed when handling Visio files, remove it if you would like to use Visio support
    dependencies {
        exclude(dependency('com.github.virtuald:curvesapi'))
        exclude(dependency('commons-codec:commons-codec'))
    }

    // Relocate javax dependencies so Android does not choke
    relocate 'javax.xml.namespace', 'org.apache.poi.javax.xml.namespace'
    relocate 'javax.xml.stream', 'org.apache.poi.javax.xml.stream'
    relocate 'javax.xml.XMLConstants', 'org.apache.poi.javax.xml.XMLConstants'
}

这个对我有用：

    packagingOptions {

    exclude 'META-INF/LGPL2.1'
    exclude 'META-INF/spring.schemas'
    exclude 'META-INF/spring.tooling'
    exclude 'META-INF/INDEX.LIST'
    exclude 'META-INF/spring.handlers'
}
configurations {
    all*.exclude module: 'classworlds'
