How to throw exception in jenkins pipeline?

Question

I have handled the Jenkins pipeline steps with try catch blocks. I want to throw an exception manually for some cases. but it shows the below error.

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.io.IOException java.lang.String

I checked the scriptApproval section and there is no pending approvals.

If you want to abort your program on exception, you can use pipeline step error to stop the pipeline execution with an error. Example :

try {
  // Some pipeline code
} catch(Exception e) {
  // Do something with the exception 

  error "Program failed, please read logs..."
}

If you want to stop your pipeline with a success status, you probably want to have some kind of boolean indicating that your pipeline has to be stopped, e.g:

    boolean continuePipeline = true
    try {
      // Some pipeline code
    } catch(Exception e) {
       // Do something with the exception 

       continuePipeline = false
       currentBuild.result = 'SUCCESS'
    }

    if(continuePipeline) {
       // The normal end of your pipeline if exception is not caught. 
    }
