Jenkins - 标记构建失败并出现 NoHeadException

Question

当我尝试通过 Jenkins 标记特定构建时，我收到以下错误：

ERROR: Error tagging repo 'refs/remotes/origin/master' :
org.eclipse.jgit.api.errors.NoHeadException: Tag on repository without
HEAD currently not supported hudson.plugins.git.GitException:
org.eclipse.jgit.api.errors.NoHeadException: Tag on repository without
HEAD currently not supported    at

    ... 2 more Trying next branch Completed

当尝试在工作区中进行标记时，它工作正常，实际上附加了 HEAD，git refs 看起来很好，这可能是 Jenkins 尝试标记时在错误的工作目录中查找的问题吗？

有没有办法提取更详细的日志以及它如何尝试标记？

仅供参考 - 使用 Jenkins 2.81 和 swarm Linux 代理，最新的 Git 插件。

Answer 1

考虑actual code throwing the exception：

    try (RevWalk revWalk = new RevWalk(repo)) {
        // if no id is set, we should attempt to use HEAD
        if (id == null) {
            ObjectId objectId = repo.resolve(Constants.HEAD + "^{commit}"); //$NON-NLS-1$
            if (objectId == null)
                throw new NoHeadException(
                    JGitText.get().tagOnRepoWithoutHEADCurrentlyNotSupported);

仔细检查您的配置：请参阅“Jenkins Git plugin detached HEAD”。您需要确保 Jenkins 确实检查了一个分支。
例如，尝试添加一个包含 git status 的简单测试步骤，以验证这一点。
