How to add try catch block in Jenkins declarative syntax.?

Question

I am trying to add try catch block in Jenkins declarative pipeline but I end up with the following error, I read the document on adding try catch block for scripted pipeline syntax of Jenkins(https://jenkins.io/doc/book/pipeline/syntax/#post-conditions) but I didn't get anything on declarative syntax.

pipeline {
agent any
    stages {
        try {
            stage('Checkout') {
                steps {
                    script {
                        if (ci_branches.contains(env.BRANCH_NAME)) {
                            // Pull the code from bitbucket repository
                            checkout scm
                        }
                    }
                }
            }
        }
        catch(all) {
            currentBuild.result='FAILURE'
        }
    }
}

Jenkins ci build result

[Bitbucket] Build result notified
    org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

                   try {

               stages {
           ^

Try/catch should be inside a script when using declarative pipeline syntax. Test the following:

pipeline {
agent any
    stages {       
        stage('Checkout') {
            steps {
                script {
                    try {
                        if (ci_branches.contains(env.BRANCH_NAME)) {
                            // Pull the code from bitbucket repository
                            checkout scm
                        }
                    }
                    catch(all) {
                        currentBuild.result='FAILURE'
                    }   
                }
            }
        }        
    }
}

I will try this and I'll let you know the result

This works fine to set a build to failure and continuing the pipeline. Unfortunately: - Setting it to 'UNSTABLE' will be the same as 'FAILURE', not possible to get a yellow bullet. - It is only possible to set the status of the whole build, there is no currentStage.result. So the stage is still green
