Android gradle在打包過程中生成重複文件httpmime

Question

當我嘗試構建我的android項目時出現此錯誤。首先我得到一個錯誤，我無法運行的東西，因爲AndroidMultiPartEntity.java中的問題，所以我添加了

compile "org.apache.httpcomponents:httpmime:4.2.3" 

在依賴項中。很多錯誤消失了，但是發生了這個錯誤。

Information:Gradle tasks [:app:assembleDebug] 

Error:duplicate files during packaging of APK C:\Users\AkerbergE\AndroidStudioProjects\incident\app\build\outputs\apk\app-debug-unaligned.apk 
    Path in archive: META-INF/NOTICE.txt 
    Origin 1: C:\Users\AkerbergE\.gradle\caches\modules-2\files-2.1\org.apache.httpcomponents\httpmime\4.2.3\118ae1bc7f3aeeddfe564f0edfd79c11d09d17d1\httpmime-4.2.3.jar

You can ignore those files in your build.gradle: 
    android { 
     packagingOptions { 
     exclude 'META-INF/NOTICE.txt' 
     } 
    } 
Error:Execution failed for task ':app:packageDebug'.

我的build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 21 
    buildToolsVersion "21.1.2" 
    packagingOptions { 
     exclude 'META-INF/notice.txt' 
     exclude 'META-INF/NOTICE.TXT'

    defaultConfig { 
     applicationId "com.example.akerberge.incident" 
     minSdkVersion 15 
     targetSdkVersion 21 
     versionCode 1 
     versionName "1.0"

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

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.android.support:appcompat-v7:22.2.0' 
    compile "org.apache.httpcomponents:httpmime:4.2.3" 
} 

Answer 1

在你的代碼

其實你寫的

exclude 'META-INF/NOTICE.TXT'

，而不是該寫：

exclude 'META-INF/NOTICE.txt'

所以，你build.gradle文件的樣子：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 21 
    buildToolsVersion "21.1.2" 

    defaultConfig { 
     applicationId "com.example.akerberge.incident" 
     minSdkVersion 15 
     targetSdkVersion 21 
     versionCode 1 
     versionName "1.0" 

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

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

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.android.support:appcompat-v7:22.2.0' 
    compile "org.apache.httpcomponents:httpmime:4.2.3" 
}
