groovy - Try-catch block in Jenkins pipeline script

I'm trying to use the following code to execute builds, and in the end, execute post build actions when builds were successful. Still, I get a MultipleCompilationErrorsException, saying that my try block is Not a valid section definition. Please help, I tried a lot reorganize the block but can't seem to be able to solve the issue.

#!/usr/bin/env groovy

pipeline{

agent any 
    try {
        stages{
            stage("Parallel 1") {
                steps {
                    parallel (
                       'firstTask' : { 
                            build( "DSL-Controll-Demo-Fibonacci-1" )
                        },
                        'secondTask' : { 
                            build( "DSL-Controll-Demo-Fibonacci-2" )
                        }
                    )
                }
            }
            stage("Feature") {
                steps {
                        build( "DSL-Controll-Demo-Fibonacci-5" )
                        build( "DSL-Controll-Demo-Fibonacci-6" )
                }
            }
            stage("Parallel 2") {
                steps{
                    parallel (
                        "thirdTask" : { 
                            build( "DSL-Controll-Demo-Fibonacci-3" )
                        },
                        "forthTask" : { 
                            build( "DSL-Controll-Demo-Fibonacci-4" )
                        }
                    )
                }
            }
        }
    }   

    catch(all) {
        currentBuild.result = 'FAILURE'
    }   

    if(currentBuild.result != 'FAILURE') {
        stages{
            stage("Post Build") {
                steps {
                    build("DSL-Controll-Demo-Fibonacci-7")
                }   
            }   
        }
    }
}

try like this (no pun intended btw)

script {
  try {
      sh 'do your stuff'
  } catch (Exception e) {
      echo 'Exception occurred: ' + e.toString()

      sh 'Handle the exception!'
  }
}

The key is to put try...catch in a script block in declarative pipeline syntax. Then it will work. This might be useful if you want to say continue pipeline execution despite failure (eg: test failed, still you need reports..)
