我按照本教程使用 GIT 和 Maven 设置 Jenkins（稍作更改，因为我使用的是 Linux CenOS）。
我正在尝试在GitHub 的 Demo Maven 项目上测试我的设置
Jenkins 在尝试执行 Maven 时抛出异常。所以我尝试 git-clone 项目并手动运行 Maven，它工作正常。
所以问题在于 Jenkins 运行 Maven。我尝试在谷歌上搜索问题，但找不到任何有用的信息。
我目前的怀疑是：
- 也许 Jenkins 没有使用正确的类路径来执行 Maven。这可能是由于缺乏读取文件的权限，因为 Jenkins 在 linux 上有自己的用户（名为 jenkins）。
- 也许 Maven 没有正确安装。我手动安装了它，而不是让 Jenkins 为我安装它，因为我需要这个设置离线工作。
这是 Jenkins 的控制台输出：
