Jenkinsfile

node {
    SayHello "Mr Jenkins"
}

SayHello.groovy

#!/usr/bin/env groovy

def call(name) {
    echo "Hello the ${name}"
}

I get this same error but my casing is correct. Is there a good way to troubleshoot this?

@mhedgpeth did you get an answer to this?

The variable name should be sayHello or similar, per the docs: https://jenkins.io/doc/book/pipeline/shared-libraries/#defining-custom-steps
