Try, catch breaking Jenkins pipeline parseScript

I tried to implement an automatic cleanup of a failed Jenkins pipeline, so that docker-compose will delete the Docker containers.

Unfortunately this creates an error in the run. What have I done wrong?

stage('Verification') {
  steps {
    try {
      sh '''
      docker-compose exec -T cli drush status
      docker-compose exec -T cli curl http://nginx:8080 -v
      if [ $? -eq 0 ]; then
        echo "OK!"
      else
        echo "FAIL"
        /bin/false
      fi
      docker-compose down
      '''
    }
    catch (e) {
      sh 'docker-compose down'
      throw e
    }
  }
}

Error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 37: Expected a step @ line 37, column 9.
           try {
           ^

You can use a post step to tear down your docker-compose installation at the end of your job

pipeline {
    agent any
    stages {
        stage('Example') {
            steps {
              sh '''
                docker-compose exec -T cli drush status
                docker-compose exec -T cli curl http://nginx:8080 -v
              '''
            }
        }
    }
    post { 
        always { 
            sh 'docker-compose down'
        }
    }
}

You should put the try-catch inside script step.

script {
  try {
  }
  catch(e) {
  }
}
