如何在 Mac 上设置 Jenkins 从属代理以使用 Plastic 检索文件？

Question

我在 Ubuntu 上有一个 Jenkins 服务器运行；资源在 Plastic 上，我已经有一个 Windows slave making Android 构建，所以 Plastic 服务器对 Jenkins 的响应很好。

我尝试在 Mac 上为 IOS 构建项目，但是在获取源时作业失败 java 异常

java.io.IOException: error=2, No such file or directory

我试图删除作业的源代码管理，只是运行一些命令，如 :

cm status

它失败了，所以我更新了 PATH 环境变量以使其工作。现在可以手动命令了，但仍然不能用于自动塑料拉动。

我将作业配置为使用 PlasticSCM Plugin 使用选择器从中提取：

repository "MyRepo"
  path "/"
    smartbranch "/My/Branch"

这是完整的错误：

[test-mac] $ cm find changeset where date between '2019-05-27T11:14:36' and '2019-05-27T11:15:43' and branch='/My/Branch' on repositories 'MyRepo' --xml --dateformat=yyyy'-'MM'-'dd'T'HH':'mm':'ss

我认为问题可能与以下 Jenkins 错误有关： https://issues.jenkins-ci.org/browse/JENKINS-17157（使用cygwin在ssh中没有加载环境变量）

如果您的从站通过 SSH 连接到您的 Jenkins 服务器，环境变量将丢失，因此您无法运行 "cm" 命令。以下 link 可能有用：(https://support.cloudbees.com/hc/en-us/articles/229724088-How-to-set-up-a-Jenkins-agent-to-have-the-same-path-as-the-user-when-connected-via-Remote-Desktop-)

过去，我们尝试通过 "Java Web Start"（而不是通过 SSH）连接从站，但我们无法通过丢失的 PATH 变量重现此问题（只有通过 SSH 连接时才会发生）。

在 macOS 上： - 运行: 例如：

sudo java -jar agent.jar -jnlpUrl http://MySERVER84/computer/macOsJava/slave-agent.jnlp -secret f5dcf86e0ceed3f22c08bc27fa07d680aff3e11c25452677af4fee218bcfb1aa -workDir "/tmp"
