Check a plugin exists within a Jenkins Pipeline (Groovy)

Question

I want to use the Slack Notification Plugin in my pipelines, which is very easy:

slackSend color: 'danger', message: 'Everything broke'

However, I don't want the build to break if slackSend doesn't exist. Is there a way to check that first?

Answer 1

You might be able to wrap it in a conditional, though I'm not sure how Jenkins adds stuff to the scripts...

if(this.respondsTo('slackSend')) {
    slackSend color: 'danger', message: 'Everything broke'
}
