Gradle 构建失败 - Apache HttpEntity

Question

当我尝试运行我的应用程序时出现此错误：

Information:Gradle tasks [:app:assembleDebug]
Warning:Dependency org.apache.httpcomponents:httpclient:4.3.5 is ignored for debug as it may be conflicting with the internal version provided by Android.
         In case of problem, please repackage it with jarjar to change the class packages

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

这是我的 build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "..."
        minSdkVersion 14
        targetSdkVersion 22
        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-v7:22.0.0'
    compile 'com.android.support:support-v4:22.0.0'
    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5'
    compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') {
        exclude module: 'org.apache.httpcomponents:httpclient'
    }

}

我只想导入以下库：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;

所以我可以运行以下代码：

       String sendProfileData = getResources().getString(R.string.URL);

        DefaultHttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(sendProfileData);

        MultipartEntity mpEntity = new MultipartEntity();

        try {
            mpEntity.addPart("first_name", new StringBody("Jay"));
            mpEntity.addPart("last_name", new StringBody("Shmidt"));
            ...
        }
        ...

这里到底出了什么问题——我真的需要删除或替换 jar 文件吗？为什么 gradle 不处理这个？

任何建议都会非常有帮助。提前致谢！

更新：我从这篇文章中得到了答案

Android Gradle plugin 0.7.0: "duplicate files during packaging of APK"

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

Answer 2

这在 Android Studio 中没有问题，只是您的系统需要互联网连接

1. 只是扩展类 MultipartEntity
2. 比按 Alt+Enter
3. 比点击在网络上查找 jar
4. 选择httpmime-4.0-alpha4.jar
5. 比右键单击项目结构
6. 点击打开模块设置
7. 在依赖项选项卡中单击右侧的 + 图标
8. 比点击文件依赖选择http:mime文件添加
9. 最终构建项目
