为什么Jenkins中的GIT插件无法连接到GIT存储库？

Question

我试图使用GIT插件Jenkins从GIT中获取代码,并且该作业正在从属机器上运行.

MASTER 系统有 http_proxy=mycom.domain.com:80

在SLAVE系统中没有http_proxy定义.

每当我在SLAVE机器中进行本地git clone时它都能很好地工作,但是从Jenkins我没有成功.

它抛出以下错误:

Building remotely on SLAVE in workspace /data/test

是因为MASTER系统试图设置系统中不存在的http代理SLAVE吗？

如果是,如何预防呢？

或者,还有其他我想念的东西？

Answer 1

原来是代理问题。

当使用 Jenkins 从 GIT 提取代码时，它设置为http_proxy（mycom.domain.com:80机器MASTER代理），并且机器中不需要该代理SLAVE。

因此，我刚刚将 GIT URL 添加到(Manage Jenkins -> Manage Plugins -> Advanced -> HTTP Proxy Configuration -> Added GIT URL in No Proxy Host field)Jenkins 中的“无代理主机”部分，现在它工作正常。
