How to throw an error if a parameter is empty?

[chencho m-a]

Hi, 

I have some parameters and i would like to check if they are empty, and if so, dont start the build. 

Any clue?

Thank you

Hi,
How about this:

env.FIELD1 = params.FIELD1
switch(FIELD1) {
case "ABCD":
env.p4 = '/usr/bin/p4'
env.awk = 'awk'
break
case ""::
currentBuild.result = 'SUCCESS'
return
break

@Haibinh is that a bash answer? 

@chencho -- are you looking for a solution in bash, or groovy? Declarative or scripted?

You can try executing a basic script that exits 1 if the parameter is not defined (something like -z $parameter) as the first step in the build.

What i want is that when you press the build button, a pop up or error at some point appears and stops the execution. 

I think that you need to overload the button in any way, but i dont know how to do it.

What you're describing exactly is not possible by default.

It /might/ be possible with custom development, but I would certainly not recommend it for such use case.
