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

Question

对于改进 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 merge 行为，作为 jenkins 管道的一部分。凭证存储在 jenkins 凭证存储中。使用 sh 调用 git 命令不会使用凭证存储，因此会失败。相反，我们尝试使用 Git Client Plugin 。但这里我们遇到了一个问题，那就是 FetchCommand execute() 失败，堆栈跟踪如下。遗憾的是 git 客户端插件的文档非常稀疏，所以我尝试了我可以在网上找到的内容:

• 使用 GitClient 的 addDefaultCredentials 和 setCredentials 方法手动设置凭据
• 使用 GitClient 的方法 setRemoteUrl 手动设置目标存储库的远程 URI

获取命令设置如下:

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

targetRepo 是获取来源，也设置为远程 url

refSpecs 是 org.eclipse.jgit.transport.RefSpec 的列表，其中包含 +refs/heads/master:refs/remotes/origin/master ，这对于我们当前的测试用例应该足以检查我们的master。

执行时发生异常。

Answer 1

问题是由于客户端需要指定其工作目录(即，如果未提供任何工作目录，则它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 客户端创建解决了该问题

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

至

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