git - Jenkins Git 插件分离 HEAD

Question

我是 Git 和 Jenkins 的新手。我的问题是我无法让 Jenkins Maven 发布插件工作。

当我使用 Jenkins 构建一个通用的 Maven 构建时，它运行良好，但是当我尝试使用 Maven 发布插件执行发布时，我得到以下堆栈跟踪:

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.3.2:prepare (default-cli) on project parent: An error is occurred in the checkin process: Exception while executing SCM command.

失败的命令和错误信息是:

/var/lib/jenkins/workspace/test_maven/parent && git symbolic-ref HEAD
[INFO]  Working directory:

我发现 Jenkins Git 插件创建了一个分离的 HEAD 引用“(无分支)”，我认为这是导致问题的原因。但我完全不知道为什么要创建这个 ref 或如何解决这个问题。

如有任何帮助，我将不胜感激。

Answer 1

Checkout/merge to local branch (optional) 字段在当前 (2.2.1) 版本的 Git 插件中消失了。

它已移至其他行为 → checkout 到特定的本地分支:

将该值设置为 master 让我得到了一个 checkout 的分支而不是一个分离的头。
