即使定义了变量,Jenkins管道也会在后期提供“无此类属性”

时间:2018-10-06 06:44:57

标签: jenkins groovy jenkins-pipeline

在我的管道中,我首先定义:

def stageCompile = ':x:'
def stageDependencies = ':x:'
def stageTest = ':x:'
def stageClient = ':x:'
def stageArchive = ':x:'

然后,每个阶段成功更改此变量,如下:

stageCompile = ':white_check_mark:'

现在,在post阶段中,我尝试发送松弛通知(为简单起见,在下面用回显替换):

post {
    unstable {
        slackNotify()
    }
    success {
        slackNotify()
    }
    failure {
        slackNotify()
    }
}

void slackNotify() {
    echo stageDependencies
    echo stageCompile
    echo stageTest
    echo stageClient
    echo stageArchive
}

这会打印stageDependencies,但给我stageCompile的错误:

我不太了解这里发生了什么。我尝试对其进行调试,并注释了stageCompile,但对于下一个变量stageTest却给出了相同的错误。有什么想法吗?

2 个答案:

答案 0 :(得分:2)

您正在使用声明性管道。为了使其工作,将变量包装在环境块中,如下所示:

pipeline {
    environment{
        stageCompile = ':x:'
        stageDependencies = ':x:'
        stageTest = ':x:'
        stageClient = ':x:'
        stageArchive = ':x:'
    }
    agent any
    stages {
        stage('Dependencies') {
            steps{
                script
                {
                    stageDependencies = "Dependencies OK"
                }
            }
        }
        stage('Compile') {
            steps{
                script
                {
                    stageCompile = "Compile OK"
                }
            }
        }
        stage('Test') {
            steps{
                script
                {
                    stageTest = "Test OK"
                }   
            }
        }
        stage('Client') {
            steps{
                script
                {
                    stageClient = "Client OK"
                }
            }
        }
        stage('Archive') {
            steps{
                script
                {
                    stageArchive = "Archive OK"
                }   
            }
        }
    }
    post { 
        always { 
            slackNotify()
        }
    }
}

void slackNotify() {
    echo stageDependencies
    echo stageCompile
    echo stageTest
    echo stageClient
    echo stageArchive
}

您所做的工作在脚本化管道中可以很好地工作,该管道的语法与声明性语法不同。

答案 1 :(得分:0)

要添加到Krzysztof的答案中,此代码也无法在脚本化管道中运行,它将在方法调用时产生以下错误:

groovy.lang.MissingPropertyException: No such property: stageDependencies for class: WorkflowScript

这是由于您试图在一种方法中访问脚本变量而导致的。将值设置为环境变量可以解决问题,但这当然不是最佳方法。
如果要在方法中使用变量,则可以在实现方法的类中定义一个字段并将其设置为该变量,或者在不指定其数据类型或 def 关键字的情况下声明该变量。 。这种方式将变量添加到脚本绑定(groovy.lang.Binding)中,从而可以在方法中对其进行访问。

例如:

class Slack {
    public String stageCompile
    public String stageDependencies

    public void slackNotify() {
        echo stageDependencies
        echo stageCompile
    }
}

Slack obj = new Slack()
obj.stageCompile = ':white_check_mark:'
obj.stageDependencies = ':x:'
obj.slackNotify()

或者简单地:

stageComile = ':white_check_mark:' // becomes a binding variable

void slackNotify() {
    echo stageCompile
}

slackNotify()
