java - Jenkins Git 客户端插件无法执行 FetchCommand

问题描述

对于一个改进 CI 工作流程的项目，我们目前正在为特定分支实现某种自动合并行为，作为我们 jenkins 管道的一部分。凭据存储在 jenkins 凭据存储中。调用 git 命令 usingsh不使用凭证存储，因此失败。相反，我们尝试使用Git Client Plugin。但是在这里我们遇到了一个问题，即FetchCommandexecute()失败并出现下面的堆栈跟踪。遗憾的是 git 客户端插件的文档非常稀少，所以我尝试了我可以在网上找到的内容：

要获取的命令设置如下：

gitclient.fetch_().from(targetRepo, refSpecs).execute()

targetRepo 是从中获取的来源，也设置为远程 url

refSpecs 是一个org.eclipse.jgit.transport.RefSpec包含+refs/heads/master:refs/remotes/origin/master哪些列表，对于我们当前的测试用例来说应该足以检查我们的 master。

执行时发生异常。

解决方案

问题是由于客户端需要指定他们的工作目录（即，如果没有提供，他们不使用当前工作空间，而是使用一些未知目录）

通过更改 git 客户端创建从

Git.with(TaskListener.NULL, env.getEnvironment()).getClient()

至

Git.with(TaskListener.NULL, env.getEnvironment()).in(new java.io.File(pwd())).getClient()
