Suppose there are 9 stages in a Jenkins pipeline and I want to jump to 7th stage if the 3rd stage fails in the pipeline.

What I have tried:

I am new to jenkins and have searched it can be achieved with "when" keyword. Not sure what conditon can be used in the expression part.

stage('stage3'){
when {
expression { }
}
}
