NoSuchFieldError INSTANCE at org.apache.http.impl.io.DefaultHttpRequestWriterFactory

java version "1.7.0_71" 
Gradle 2.1

你好

UPDATE:

依赖关系

gradle dependencies | grep httpcore
|    +--- org.apache.httpcomponents:httpcore:4.3.3
|    +--- org.apache.httpcomponents:httpcore:4.3.3
|    +--- org.apache.httpcomponents:httpcore:4.3.3
|    +--- org.apache.httpcomponents:httpcore:4.3.3
|    |         |    |         |    +--- org.apache.httpcomponents:httpcore:4.1 -> 4.3.3
|    +--- org.apache.httpcomponents:httpcore:4.3.3
|    |         |    |         |    +--- org.apache.httpcomponents:httpcore:4.1 -> 4.3.3

这是否意味着我有4.1是4.3.3的软链接？看起来很奇怪，因为当我打印出类加载器正在加载的内容时，它似乎加载了4.3.3：看起来很奇怪。/home/steve/.gradle/caches/modules-2/files-2.1/org.apache.httpcomponents/httpcore/4.3.3/f91b7a4aadc5cf486df6e4634748d7dd7a73f06d/httpcore-4.3.3.jar

当我尝试运行我的httpClient时，我一直收到此错误。一切编译正常。

java.lang.NoSuchFieldError: INSTANCE
        at org.apache.http.impl.io.DefaultHttpRequestWriterFactory.<init>(DefaultHttpRequestWriterFactory.java:52

我的代码很简单，去掉了不重要的代码，让它保持小：

public class GenieClient {
    private CloseableHttpClient mClient;

    public GenieClient() {
        ClassLoader classLoader = GenieClient.class.getClassLoader();
        URL resource = classLoader.getResource("org/apache/http/message/BasicLineFormatter.class");
        log.log(Level.INFO, "resource: " + resource);

        mClient = HttpClientBuilder.create().build();
    }

    public int sendRequest() {   
        int responseCode = -1;

        try {
            HttpResponse response = mClient.execute(new HttpPost("http://www.google.com"));
            responseCode = response.getStatusLine().getStatusCode();
        }
        catch(IOException ex) {
            log.log(Level.SEVERE, "IOException: " + ex.getMessage());
        }

        return responseCode;
    }
}

我从classLoader获得的输出是这样的：

INFO: resource: jar:file:/home/steve/.gradle/caches/modules-2/files-2.1/org.apache.httpcomponents/httpcore/4.3.3/f91b7a4aadc5cf486df6e4634748d7dd7a73f06d/httpcore-4.3.3.jar!/org/apache/http/message/BasicLineFormatter.class

我使用gradle作为我的构建工具，并在我的文件中设置了这样的依赖项：build.gradle

dependencies {
    compile 'org.apache.httpcomponents:httpclient:4.3.6'
}

我也尝试包含以下httpcore，但仍然得到相同的错误：

compile 'org.apache.httpcomponents:httpcore:4.4'

一切都构建正常，只有当我运行我的httpClient时，

非常感谢您的任何建议，
