Jenkins Job DSL：未知 return 语句

Question

几天前，我遇到了一段用于覆盖 Jenkins 插件默认配置的代码片段“GitHub SCM Source”（未知作者）：

Closure configOverride(String repo, int id, String cred) {
return {    
    it / sources / 'data' / 'jenkins.branch.BranchSource' << {
        source(class: 'org.jenkinsci.plugins.github_branch_source.GitHubSCMSource') {    
            id(id)    
            scanCredentialsId(cred)    
            checkoutCredentialsId('SAME')    
            repoOwner('owner')    
            repository(repo) 
            includes('*')    
            buildOriginBranch('true')    
            buildOriginBranchWithPR('true')    
            buildOriginPRMerge('false')    
            buildOriginPRHead('false')    
            buildForkPRMerge('true')    
            buildForkPRHead('false')    
         }
      }
   }
}

一切都很好，除了我无法理解以下行：

it / sources / 'data' / 'jenkins.branch.BranchSource' << { ... }

我试图找到一些关于在 groovy 中使用“/”的解释，但没有成功。可能我不知道具体要搜索什么。

有人可以帮我 link 文档或简短的解释。

Answer 1

这是超载运算符

Groovy allows you to overload the various operators so that they can be used with your own classes. Consider this simple class:
class Bucket {
    int size

    Bucket(int size) { this.size = size }

    Bucket plus(Bucket other) {                     
        return new Bucket(this.size + other.size)
    }
}
Just by implementing the plus() method, the Bucket class can now be used with the + operator like so:
def b1 = new Bucket(4)
def b2 = new Bucket(11)
assert (b1 + b2).size == 15    

对于 / 将覆盖 T div(T x)

此代码片段在 Jenkins DSL 中用于“multibranchPipelineJob”。闭包 configOverride 用于生成一个 XML 对象，该对象替换以下路径“sources/data/jenkins.branch.BranchSource”.

中 config.xml 中的默认配置
