Is it possible to suppress the stack trace from a thrown Exception in groovy declarative pipelines?-CodePudding

I have a declarative pipeline with an input step where it is possible to put the wrong input. I have wrapped the stage in a retry block and thrown Exceptions if the input is found to be invalid.

if (isValid == 1) {
   println("Erroring out due to invalid change ticket")
   throw new Exception("Please rerun the job and enter a valid change ticket")
} else {
   println("CHG ticket is valid")

If this exception is thrown the stage is restarted.

The pipeline console spits this out:

ERROR: Execution failed
java.lang.Exception: Please rerun the job and enter a valid change ticket

Retrying
[Pipeline] {
[Pipeline] timeout
Timeout set to expire in 1 day 0 hr
[Pipeline] {
[Pipeline] input
Input requested

But I only care for the message I passed with the Exception.

Is there a way to suppress the stacktrace from this Exception in the Jenkins console?

CodePudding user response：

Use error step (Error Step)

error: Error signal Signals an error. Useful if you want to conditionally abort some part of your program. You can also just throw new Exception(), but this step will avoid printing a stack trace.

if (isValid == 1) {
  println("Erroring out due to invalid change ticket")
  error("Please rerun the job and enter a valid change ticket")
} else {
  println("CHG ticket is valid")
}
