Jenkins 2.0管道项目中的Mercurial结帐

Question

我们是jenkins 2.0的新手。我们要做的是定义一个Jenkinsfile并在第一阶段完成结账。我们试图从我们的mercurial存储库检查我们的项目，但我们遇到了其他问题。问题： 可以使用mercurial插件吗？

我们试图为：

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

，但得到这个exeption：

java.lang.NullPointerException

是否有任何人谁可以帮助我们这个问题？

Answer 1

这是为我工作：

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

Answer 2

任何有兴趣的拉动只有特定的分支，或者说Mercurial库的tip，这个工作对我来说：

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