Jenkins 2.0管道項目中的Mercurial結帳

Question

我們是jenkins 2.0的新手。我們要做的是定義一個Jenkinsfile並在第一階段完成結賬。我們試圖從我們的mercurial存儲庫檢查我們的項目，但我們遇到了其他問題。問題： 可以使用mercurial插件嗎？

我們試圖爲：

checkout([$class: 'MercurialSCM', branches: [[name: '*/default']], userRemoteConfigs: [[url: 'https://pathToOurRepo.com']]]) 

，但得到這個exeption：

java.lang.NullPointerException

是否有任何人誰可以幫助我們這個問題？

Answer 1

這是爲我工作：

checkout scm: [$class: 'MercurialSCM', source: 'ssh://hg@bitbucket.org/user/repo', clean: true, credentialsId: '1234-5678-abcd'], poll: false

Answer 2

任何有興趣的拉動只有特定的分支，或者說Mercurial庫的tip，這個工作對我來說：

checkout scm: [$class: 'MercurialSCM', 
    source: 'ssh://hg@bitbucket.org/username/repo-name', 
    revision: 'tip', 
    clean: true, 
    credentialsId: '{your-jenkins-bitbucket-creds}'], 
poll: false
