Jenkins：GitSCM在一个分离头状态下完成了克隆，我怎样才能确保 checkout 正确的分支名称？

我写了一个Jenkins管道来克隆一个git仓库并运行一个MSBUILD构建。
我使用GitSCM将存储库克隆到工作区，如下所示：

stage ('Checkout SCM & Merge master to feature branch') {
    checkout([$class: 'GitSCM', branches: [[name: '*/feature/*']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '99f978af-XXXX-XXXX-8147-2cf8f69ef864', url: 'http://TFS_SERVER:8080/tfs/DefaultCollection/PC_International/_git/REPO_NAME']]])
}

在克隆repo的步骤发生之后，HEAD指向一个分离的头，我不明白为什么。

不仅如此，我们知道在运行Jenkins pipeline时，git参数不能正确求值，因此我不能简单地通过运行以下命令来修复它：

git checkout ${BRANCH_NAME}

那么，在开始MSBUILD步骤之前，如何确保HEAD指向分支名称呢？
我相信已经有人遇到这种情况，并有一个解决方案。

经过大量的研究，甚至联系Jenkins专业人士和许多尝试，从我这边，我找到了如何解决这个问题。
以下代码修复了该问题：

checkout([$class: 'GitSCM', branches: [[name: '*/feature/*']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'LocalBranch', localBranch: "**"]], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '99f978af-XXXX-XXXX-8147-2cf8f69ef864', url: 'http://TFS_SERVER:8080/tfs/DefaultCollection/Product/_git/Project']]])

注意localBranch扩展名中的"**"。

添加[[$class: 'LocalBranch', localBranch: "**"]]修复了我的问题。
使用GitSCM插件成功检出主分支后，.git/refs/heads/master仍然缺失，导致某些操作始终失败（例如，git log --decorate ...创建变更日志）。

如果您想使用Pipeline配置实现相同的行为，请使用Pipeline-〉Additional Behaviours -〉Checkout to specific local分支-〉在输入字段中插入分支名称（或'**'）。

如https://stackoverflow.com/a/61063557/6776354中所述，将checkout scm更新为

def scmVars = checkout([
                    $class: 'GitSCM',
                    branches: scm.branches,
                    extensions: scm.extensions, 
                    userRemoteConfigs: [[
                        credentialsId: scm.userRemoteConfigs[0].credentialsId,
                        name: 'origin', 
                        refspec: '+refs/heads/*:refs/remotes/origin/*', 
                        url: scm.userRemoteConfigs[0].url
                    ]],
                    doGenerateSubmoduleConfigurations: false
                ])

对我很有效。这确保了所有分支都可用。
