Jenkins MultiBranchPipeline首先加载共享库存储库

Question

我遇到了一个问题，即在我的MBP作业中检索主存储库之前检索共享库。在我的日常工作和自由式工作中，情况并非如此。由于Jenkinsfile共享库方法尝试从主存储库读取Xcode的版本，因此MBP作业失败，并显示以下错误。这是可以理解的，因为存储库还没有被签出。这在常规管道作业中工作得很好，在常规管道作业的日志中，我可以看到在共享库之前发生了轻量级的签出。在MBP中，有没有办法强制在共享库之前签出主存储库？

我花了一段时间才发现的解决方案是使用MBP plugin DSL类和方法来公开GitSCM作业配置中定义的git url和分支。这两个对象允许您在签出函数调用中使用GitSCM稀疏签出，并指定特定的文件或文件目录。不需要curl或wget或凭证插值。精确的命令语法如下：

此代码允许您签出共享库中的单个文件，该库包含在配置的作业的Jenkinsfile中的节点块之前调用的代码。

def scmUrl = scm.getUserRemoteConfigs()[0].getUrl()
def branch = scm.getBranches()

checkout ([
  $class:'GitSCM',
  branches: branch,
  doGenerateSubmoduleConfigurations: false,
  extensions: [
    [
      $class: 'SparseCheckoutPaths',
      sparseCheckoutPaths: [[path: '/myDirectory/singlefile.txt']]
      ]
  ],
  submoduleCfg:[],
  userRemoteConfigs: [[url:scmUrl]]
])
