[FIXED] Error puting jenkins stage inside a function definition

Issue

I am using scripted pipeline and trying to put my stage inside a function as below.

   node{
          if(value=="true")
             {
              def func(){
                       stage ('first stage')
               }
              }      
              fun() #calling it here. 

}

its not working. it says method definition not expected here

Method definition not expected here. Please define the method at an appropriate place or perhaps try using a block/Closure instead.

. How to do this? its not possible to define outside node block as the pipeline is running on a particular node.

Solution

Without executing the stage, you can return the stage configurations from a function. Please refer to the following.

node {
    stage('Stage 1') {
       echo "This stage executed always"
    }
    def value = true
    // Lets execute stage 2
    if(value == true) {
        generateStage("Stage 2").call()
    }
    
    stage('Stage3') {
        echo "Stage 3"
    }
}

def generateStage(name) {
    return {
        stage("Stage ${name}") {
            echo "Stage ${name}"
        }
    }
}
