Jenkins 拉取请求生成器

Question

我为 Jenkins 设置了父子作业。父作业配置为在拉取请求上执行，子作业由父作业触发。

我的父作业配置，

在源代码管理部分下，

Repository URL: https://github.com/myorg/myrepo.git
Name: origin
Refspec: +refs/pull/*:refs/remotes/origin/pr/*
Branch Specifier (blank for default): ${sha1}

在构建部分下，

Trigger/call builds on other projects : 
Current build parameters
Pass-through Git Commit that was built

我的子作业配置，

在源代码管理部分下，

Repository URL: https://github.com/myorg/myrepo.git
Name: blank
Refspec: blank
Branch Specifier (blank for default): blank

问题：

子作业执行时出现错误，

父作业控制台，

知道如何解决这个问题吗？

Answer 1

您还需要为子项目指定 refspec (+refs/pull/:refs/remotes/origin/pr/) 和分支说明符 (${sha1})。
