Jenkinsfile defined in objects and functions, access to git author, a notification is sent nails

Since the beginning of the use of Jenkinsfile after Jenkins configured as rampant as CI developers to customize the script is too convenient.

For example, recently developed a project to involve people, to submit a lot of conflict, and some people did not compile their own submitted, resulting in the back of people are blocked, so we need to tell him: Submit failed.

First, Jenkinsfile should be how to use it, see: https://www.cnblogs.com/woshimrf/p/gitlab-with-jenkins.html

When you want to define Jenkinsfile nail notice, first of all get git Submitted by:

最外层：

class MyChange {
   String author;
   String msg;
}
@NonCPS
def getChanges()
{
    def changeLogSets = currentBuild.changeSets
    for (int i = 0; i < changeLogSets.size(); i++)
    {
        def entries = changeLogSets[0].items
        for (int j = 0; j < entries.length; j++)
        {
            def entry = entries[0]
            def change = new MyChange()
            change.author = entry.author
            change.msg = entry.msg
            return change
        }
    }

}

然后在node节点里定义变量

ding_group_access_token = "c20d35654da77a99d8869e04xxxxxxxd1a81aasssa2"
ding_jenkinsUrl = "http://jenkins.ryan.com/view/我的view名称/"

最后在失败的时候通知：


stage('Compile And UnitTest') {
    echo "2.Compile the code"
    try {
        sh "mvn clean install"
    } catch (Exception ex) {
        updateGitlabCommitStatus name: 'build', state: 'failed'
        def change = getChanges()
        dingTalk accessToken: "${ding_group_access_token}", imageUrl: '', jenkinsUrl: "${ding_jenkinsUrl}", message: "@所有人 构建失败@$change.author $change.msg" , notifyPeople: "$change.author"
        throw ex;
    } finally {

    }

    updateGitlabCommitStatus name: 'build', state: 'success'
}

The final Jenkinsfile might look like this

文件位置
my-project
- .deploy
   - Jenkinsfile
- src

Create a pipeline job in jenkins years, and specify Jenkinsfile

Jenkinsfile

class MyChange {
   String author;
   String msg;
}
@NonCPS
def getChanges()
{
    def changeLogSets = currentBuild.changeSets
    for (int i = 0; i < changeLogSets.size(); i++)
    {
        def entries = changeLogSets[0].items
        for (int j = 0; j < entries.length; j++)
        {
            def entry = entries[0]
            def change = new MyChange()
            change.author = entry.author
            change.msg = entry.msg
            return change
        }
    }

}
