无法运行罐子摇篮的HttpClient Dependecy

我试图运行一个jar文件后，我建立在的IntelliJ gradle这个，但我发现了以下错误：无法运行罐子摇篮的HttpClient Dependecy

Error: A JNI error has occurred, please check your installation and try again

我的build.gradle看起来像这样：

dependencies { 
    compile 'org.apache.httpcomponents:httpclient:4.5.3' 

    testCompile group: 'junit', name: 'junit', version: '4.11' 
}

我已经在IntelliJ中的模块settigns中检查了httpcomponents和commons-codec的依赖关系。

的源代码：

package com.jshah; 

import org.apache.http.HttpResponse; 
import org.apache.http.client.HttpClient; 
import org.apache.http.client.methods.HttpGet; 
import org.apache.http.impl.client.HttpClientBuilder; 

import java.io.BufferedReader; 
import java.io.InputStreamReader; 

import static org.apache.http.HttpHeaders.USER_AGENT; 


public class Runner { 
    public static void main(String[] args) { 
     final String url = "http://reddit.com/api/trending_subreddits"; 

     try { 
      HttpClient client = HttpClientBuilder.create().build(); 
      HttpGet request = new HttpGet(url); 

      request.addHeader("User-Agent", USER_AGENT); 
      HttpResponse response = client.execute(request); 

      System.out.println(response.getStatusLine()); 

      // Get the response 
      BufferedReader rd = new BufferedReader 
        (new InputStreamReader(
          response.getEntity().getContent())); 

      String line; 
      while ((line = rd.readLine()) != null) { 
       System.out.println(line); 
      } 
     } 
     catch (Exception e) { 

     } 
    } 
}

你只是建立你的项目，通过调用：gradle这个版本（无需添加任何额外的插件，Java的除外）？如果是这样，你的jar中没有httpclient类。您需要使用FatJar或Copy dependencies来构建您的项目。

您还可以扩展jar任务来收集依赖关系并将其打包，但请注意，这不是首选解决方案。我只将它用于一些小应用程序或测试。强烈建议使用插件。

jar { 
archiveName = 'Name.jar' 

manifest { 
    attributes 'Main-Class': 'your main', 
      'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' '), 
      'Implementation-Version': project.version 
} 

from(configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }) 
}
