java.lang.ClassNotFoundException: org.apache.http.util.Args - 我应该添加哪个依赖项？

Question

我是运行一个 Java 应用程序并且有以下错误：

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

我认为问题在于某个图书馆试图通过反射使用此 org.apache.http.util.Args class，但未找到它。

我应该在我的 Maven pom.xml 文件中添加什么来解决这个依赖关系？

我的 class 路径已经包含以下应该与此 class 相关的参考：

<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"/>

我的 pom.xml 文件：

Answer 1

您需要添加以下依赖：

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

对于未来：通常，您最喜欢的搜索引擎可以告诉您需要哪个 jar 文件；搜索

"org.apache.http.util.Args which jar"
