Jenkins的pipeline如何“修剪陈旧的远程跟踪分支”？

Jenkins出现了陈旧的分支和远程git服务器有冲突, 如下:

ERROR: Error fetching remote repo 'origin'

在网上找了很多方法都不行, 去国外网站找了一圈也没有答案, 想了想, Jenkins的git流水线插件不应该做得那么搓, 绝对会把这个问题考虑进去了, 从生产流水线语法入手查查有没有更好的方法:

流水线语法的入口有2个地方:

1)

2) 

进去之后呢, 如下:

看的时候感觉上面部门, 就是一些git的常用配置, 感觉都没有特别, 再往下一看:

没错, 就是它(PruneStaleBranch), 可以修建修剪陈旧的远程跟踪分支, 在这里补上, 重新点击构建, 成功了:
