抛出java.lang.ClassNotFoundException：org.apache.http.util.Args - 哪些依赖我应该补充的吗？ [英] java.lang.ClassNotFoundException: org.apache.http.util.Args - Which dependency should I add?

问题描述

我运行一个Java应用程序，并有以下错误：

  

抛出java.lang.ClassNotFoundException：org.apache.http.util.Args

我认为这个问题是一个库尝试使用此 org.apache.http.util.Args 类与反思，但还没找到。

我应该我在Maven的pom.xml文件添加到解决这种依赖？

我的类路径中已经包含下列内容的参考，应与这个类有关：

 ＆LT; classpathentry样=VAR路径=M2_REPO /组织/阿帕奇/ httpcomponents / HttpClient的/ 4.3.6 / HttpClient的-4.3.6.jar源路径=M2_REPO /组织/阿帕奇/ httpcomponents / HttpClient的/ 4.3.6 / HttpClient的-4.3.6-sources.jar/＆GT;

解决方案

您需要添加follwoing依赖性：

 ＆LT;＆依赖性GT;
    ＆LT;＆的groupId GT; org.apache.httpcomponents＆LT; /的groupId＆GT;
    ＆LT;＆的artifactId GT;的HttpCore＆LT; / artifactId的＆GT;
    ＆LT;＆版GT; 4.4＆LT; /版本＆GT;
＆LT; /依赖性＆GT;
 

I'm running a Java application and had the following error:

java.lang.ClassNotFoundException: org.apache.http.util.Args

I believe that the issue is that one library is trying to use this org.apache.http.util.Args class with reflection, but is not finding it.

What should I add in my Maven pom.xml file to resolve this dependency?

My classpath already contains the following reference that should be related with this class:

<classpathentry kind="var" path="M2_REPO/org/apache/httpcomponents/httpclient/4.3.6/httpclient-4.3.6.jar" sourcepath="M2_REPO/org/apache/httpcomponents/httpclient/4.3.6/httpclient-4.3.6-sources.jar"/>
<classpathentry kind="var" path="M2_REPO/org/apache/httpcomponents/httpcore/4.2.4/httpcore-4.2.4.jar" sourcepath="M2_REPO/org/apache/httpcomponents/httpcore/4.2.4/httpcore-4.2.4-sources.jar"/>

My pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

解决方案

You need to add the follwoing dependency:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4</version>
</dependency>
