Question

我编写了一个Jenkins管道，它克隆了一个git存储库并运行了一个MSBUILD版本。

我使用GitSCM将存储库克隆到工作区中，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']]])
}

克隆步骤完成后，HEAD指向一个独立的头部，我不明白为什么。

更重要的是，众所周知，在运行Jenkins管道时，git参数未正确评估，因此我无法通过运行来修复它：

git checkout ${BRANCH_NAME}

那么在启动MSBUILD步骤之前，我怎样才能确定HEAD指向分支名称？

我确定有人已经遇到这种情况并且有解决方案。

经过大量的研究，甚至联系Jenkins的专业人士和我这边的许多尝试，我找到了如何解决这个问题。

以下代码修复了此问题：

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“**”。

Answer 2

添加[[$ class：＆＃39; LocalBranch＆＃39;，localBranch：＆＃34; **＆＃34;]]也解决了我的问题。

使用GitSCM插件成功结帐主分支后，＆＃34; .git / refs / heads / master＆＃34;仍然缺少让一些操作总是失败（git log --decorate ...来创建更改日志，......）。

感谢您分享此内容。

如果您想使用流水线配置实现相同的行为，请使用流水线->附加行为-> 签出到特定的本地分支-> 在输入字段中插入分支名称（或“**”）。

Jenkins：GitSCM以一个独立的头状态完成克隆，我怎样才能确保检出正确的分支名称？
