commons-httpclientjar pom

您好！要在Maven项目中使用Apache HttpClient库，您需要向您的项目的pom.xml文件中添加以下依赖项：

<dependencies>
  <dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
  </dependency>
</dependencies>

这将添加Apache HttpClient库的最新版本到您的项目中。请确保在添加依赖项后重新构建项目以使其生效。

看起来你在使用 Maven 构建项目时遇到了一些问题。错误日志显示 Maven 找不到 `commons-httpclient:commons-httpclient:jar:3.1` 这个依赖，可能是由于连接到 Maven 仓库时出现了连接超时的问题导致的。你可以尝试再次运行 Maven 并加上 `-e` 参数来查看完整的错误堆栈信息，或者使用 `-X` 参数来启用完整的调试日志。同时，你也可以参考 Maven 的文档或者寻求社区支持来解决这个问题。
