"在 APK-META-INF/license.txt 中复制了重复的 lib 文件"Android Studio 中的错误 [英] "Duplicate lib file copied in APK-META-INF/license.txt " error in Android Studio

问题描述

我在项目中使用了以下 2 个库1. spring-core-3.1.0.RELEASE.jar2. spring-web-3.1.0.RELEASE.jar

I am using below 2 lib's in project 1. spring-core-3.1.0.RELEASE.jar 2. spring-web-3.1.0.RELEASE.jar

但 android studio 正在考虑为上述库重复输入并在打包时出错.

But android studio is considering duplicate entry for above lib's and giving error while packaging.

Error:duplicate files during packaging of APK E:\Code\iDoc\app\build\outputs\apk\app-debug-unaligned.apk
    Path in archive: META-INF/license.txt
    Origin 1: E:\Code\iDoc\app\libs\spring-core-3.1.0.RELEASE.jar
    Origin 2: E:\Code\iDoc\app\libs\spring-web-3.1.0.RELEASE.jar
You can ignore those files in your build.gradle:
    android {
      packagingOptions {
        exclude 'META-INF/license.txt'
      }
    }

有人遇到过类似的问题吗?

Anybody faced similar problem ?

请建议一些解决此错误的方法.

Please suggest some-work around for this error.

推荐答案

转到您的 build.gradle 文件并添加以下行:

Go to your build.gradle file and add the following line:

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

就我而言，我必须像这样添加:

In my case I had to add like this one:

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"


}

注意:

1. 元文件不影响应用程序的任何编程功能.元文件基本上包含文本信息，如开源库的法律声明、许可证等.排除它不会影响任何事情.

当我们使用多个 3rd 方开源库时，有时 2 个或更多项目具有相同命名的文本文件(例如:License.txt 或 Notice.txt 或 dependencies.txt).这会导致构建期间的冲突.在那一刻，我们强大的 android 工作室建议我们排除那些冲突的元文件.
