android - 将 httpcore 和 httpmime 库添加到 Android 项目中会在运行应用程序时出错

Question

在我的 Android 应用程序中，我使用了 httpcore 和 httpmime 库。我的 build.gradle 文件依赖部分包含以下部分，

compile 'org.apache.httpcomponents:httpcore:4.4.4'
compile 'org.apache.httpcomponents:httpmime:4.5.2'

当我运行应用程序时出现错误。日志如下图，

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
 > com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/NOTICE
        File1: /Users/marpak/.gradle/caches/modules-2/files-2.1/org.apache.httpcomponents/httpmime/4.5.2/22b4c53dd9b6761024258de8f9240c3dce6ea368/httpmime-4.5.2.jar
        File2: /Users/marpak/.gradle/caches/modules-2/files-2.1/org.apache.httpcomponents/httpcore/4.4.4/b31526a230871fbe285fbcbe2813f9c0839ae9b0/httpcore-4.4.4.jar

我该如何解决这个问题

Answer 1

将此添加到您的 build.gradle 文件中

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'
    }
}
