Github-Jenkins触发奴隶问题

我有一个jenkins实例,它附带了一个windows slave机器.我还有一个运行的作业,它驻留在github中,我有触发器 - "当一个更改被推送到GitHub时设置".

当我将更改推送到github时,jenkins上没有触发任何构建.我检查并看到有效负载确实在"Github挂钩日志"中转移到jenkins但我收到以下错误:

基本上抱怨无法运行命令 C:\Program Files (x86)\Git\cmd\git.exe" ls-remote -h https://xx/xx/xx master

但是当我手动进入我的从机并运行命令时,它工作正常.

请注意1.我已经进行了调整,jenkins slave服务以admin身份登录,以便它拥有所有权限.我的默认jenkins服务器是一个linux盒子,奴隶机器是一个windows盒子.显然两者都有不同的git可执行路径.所以我想知道jenkins是否出于某种原因在我的linux机器上运行此命令.

我确实有项目设置只在windows slave盒子上运行,并且工作正常,因为它构建正常(因此它能够找到作业的git可执行文件)

有什么指针吗？

也有人知道jenkins的github插件如何与slave机器一起工作(它是否在奴隶中寻找git或者它是去jenkins所在的地方,因为它可能是源,但不知道这个奇怪案例的解决方案会是什么是？)
