jenkins - 触发Multibranch Pipeline项目中的依赖作业

我正在使用Multibranch Pipeline项目来构建我的应用程序。我们有大约100多个组件，还有许多管道项目。所以说例如我们有：

项目A依赖→项目B依赖→项目C

我们正在对所有这些作业使用SCM轮询。我希望一旦构建Project C，就应该构建Project B，然后再构建Project A。我的依赖项列表因项目而异。

我知道一个Maven项目可以使用Build Triggers→☑进行构建，只要构建了SNAPSHOT依赖项，但是使用Multibranch Pipeline插件，都找不到解决该问题的方法。

有指针吗？

最佳答案

在分支机构的配置页面中构建了其他项目之后，可以进行“生成”，可以选择Build，但是不能保存分支机构的配置（分支机构侧栏中的菜单项仅显示“查看配置”，而不是“配置”）。

下面的Jenkinsfile应该可以实现您要实现的目标。将其添加到所有分支。如果发生更改，请在您的master / trunk上对其进行编辑，然后将其选择到受这些更改影响的分支上。

String[][] buildChains = [
  ['master'],
  ['branch1', 'master'],
  ['branch2', 'branch1', 'master'],
  ['no-build']
  // ... further build chains ...
  ]

for ( buildChain in buildChains ) {
  if ( buildChain[0].equalsIgnoreCase( env.BRANCH_NAME ) ) {
    int depth = 0
    for ( branch in buildChain ) {
      String depthIndicator = "+" * ++depth
      //optional: String depthIndicator = new String(new char[++depth]).replace('\0', '+')
      //optional: String depthIndicator = repeat( "+", ++depth )
      println "  $depthIndicator Triggering build for branch '$branch'"
      build( branch )
      } // for ( branches )
    break // comment this if there are more build chains for one branch
    }
  } // for ( buildChains )


def build( String branch ) {

  switch ( branch ) {
    case "master":
      buildMaster()
      break
    case ["branch1", "branch2"]:
      buildBranch( branch )
      break
 // case ...
 //   ...

    default:
      println "  --- No build defined for branch \'$branch\' ---"
    }  // switch ( branch )
  }  // build( branch )

def buildMaster()   {
  println '  Building branch \'master\'...'
  // ... build code ...
  }

def buildBranch( String branch )    {
  println "  Building branch '$branch'..."
  // ... build code ...
  }

String repeat( String s, int count ) {
  return count > 0 ? s + repeat( s, --count ) : ""
  }

在branch1上运行它：

[Pipeline] echo
  + Triggering build for branch 'branch1'
[Pipeline] echo
  Building branch 'branch1'...
[Pipeline] echo
  ++ Triggering build for branch 'master'
[Pipeline] echo
  Building branch 'master'...
[Pipeline] End of Pipeline
Finished: SUCCESS

在branch2上运行它：

[Pipeline] echo
  + Triggering build for branch 'branch2'
[Pipeline] echo
  Building branch 'branch2'...
[Pipeline] echo
  ++ Triggering build for branch 'branch1'
[Pipeline] echo
  Building branch 'branch1'...
[Pipeline] echo
  +++ Triggering build for branch 'master'
[Pipeline] echo
  Building branch 'master'...
[Pipeline] End of Pipeline
Finished: SUCCESS
