You could do this with email-ext and a pre-send script. If you set it up
such that the email is only sent if the last 5 builds were failures (you
can get the current build number and then back track and look at
the preceding builds). Then you could cancel sending the email if there
were less than 5
I am using Jenkins to automate selenium testing. I need to have a way to
send email notifications after 5 failed build attempts. I have installed
the groovy post build plugin but, I don't know how to identify failed
attempts, record failed attempts, or notify after n number of failed
attempts.
