【问题描述】：

我已经创建了 Selenium IDE 测试用例并在 Eclipse 中对其进行了测试。该项目是一个 Maven java 项目，测试将在 Eclipse 中正常运行，但是，当我将项目添加到 Jenkins 并尝试构建我的项目时，出现错误和构建失败。

错误：

【解决方案1】：

这似乎与互联网连接有关。你注意到错误了吗："Unknown host repo.maven.apache.org"？

试试wget http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.5/maven-resources-plugin-2.5.pom，看看能不能获取数据。

更多详情可以参考this链接。

你也可以试试这个...

从命令行构建时，我的 Java 项目构建成功，但在使用 Jenkins 构建时出现错误“Unknown host repo.maven.apache.org”。

问题是我们公司使用的自定义 maven 设置文件。

所以你可以做的是：在作业配置下，构建部分，点击“高级...”。将 “设置文件” 设置为 “文件系统中的设置文件”，并从您的 maven 安装位置提供设置文件的路径。例如 C:\Program Files\apache-maven-3.1.1\conf\settings.xml

将“全局设置文件”设置为“文件系统上的全局设置文件”，并给出“${user.home}/. m2/settings.xml".

【解决方案3】：

您可能落后于合作代理（或任何其他代理\防火墙）。确保您可以从正在运行构建的从属设备访问 maven Central。

如果没有 - 在您的服务器上配置您的 http_proxy 和 https_proxy。
