Jenkins-将参数传递给groovy函数

分类: 技术问答 • 2022-05-08 00:35:15
问题描述：

我一直在尝试用管道内部的参数调用另一个常规函数，但没有任何运气.
我将参数传递给的常规函数​​包含一个bash脚本，但是此bash脚本无法识别我传递给它的参数.但是，如果我传递的参数在管道中定义为parameters {}，那么它可以工作，但我不希望这样做.

I've been trying to call another groovy function with parameters inside my pipeline without any luck.
The groovy function I am passing the parameters to consists of a bash script, but this bash script does not recognize the parameter(s) I am passing to it. If however the parameter passed by i defined as a parameters {} in the pipeline, then it works, but I do not want this.

问题:
Shell脚本无法识别/理解参数，变量为空，没有值.

PROBLEM:
The shell script does not recognize/understand the arguments, the variables are empty, no value.

pipelineJenkins.groovy 

def call {
  pipeline {
    parameters { 
      string (name: VAR1, defaultValue: "Peace", description: '' }  <--- This works, but not beneficial
      string (name: VAR2, defaultValue: "Space", description: '' }  <--- This works, but not beneficial
    stages {
      stage ('Run script') {
        steps {
          groovyFunction("${VAR1}", "${VAR2}")
          groovyFunction("Peace", "Space") <--- WHAT I WANT
        }
      }
    }
  }
}

groovyFunction.groovy 

def call(var1, var2) {
  sh 'echo MY values ${var1} and ${var2}'
  sh "echo MY values ${var1} and ${var2}" <-- Works using double quotes, this messes up sed and for-loops...
}

具有参数的管道输出: 

MY values Peace and Space

没有参数的管道输出: 

MY values and

我曾尝试使用上一个问题中建议的environment{}关键字，但没有任何运气. 詹金斯-环境

I have tried using the environment{} keyword as suggested in my previous question, without any luck. Jenkins - environment

我知道那里也有类似的问题:

I am aware that there are similar issues out there:

  • Pass groovy variable to shell script
  • How to assign groovy variable to shell variable
  • Jenkins parameters

注意: 这与我的问题 Shell参数Jenkins

谢谢.

更新

我已经更新了使用环境变量而不使用environment {}

I have updated the answer to use environment variable without having environment {}

使用我在这里使用过的环境变量(我对您的代码进行了一些重构):

Use environment variables like the ones i have used here (i refactored your code a little bit):

def callfunc() {
  sh 'echo MY values $VARENV1 and $VARENV2'
}

pipeline {
    agent { label 'agent_1' }
    stages {
      stage ('Run script') {
        steps {
            script {
                env.VARENV1 = "Peace"
                env.VARENV2 = "Space"
            }
            callfunc()
        }
      }
    }
}

env.VARENV1和env.VARENV2是我在script{}内部使用的环境变量.您可以为其分配值.

env.VARENV1 and env.VARENV2 are the environment variables i have used here inside script{}. You can assign values to them.

这是我的新输出:

我真的希望它能帮上忙.

I really hope it helped.

使用环的更新

使用shell脚本的三重单引号引起循环并向其中添加grrovy变量:

Using triple single quotes for shell script for loop and adding grrovy variable to it:

def callfunc() {
  sh '''
  export s="key"
  echo $s
  for i in $VARENV1 
    do
      echo "Looping ... i is set to $i"
    done
    '''
}

pipeline {
    agent { label 'agent_1' }
    stages {
      stage ('Run script') {
        steps {
            script {
                env.VARENV1 = "Peace"
            }
            callfunc()
        }
      }
    }
}
