General error during class generation: Method code too large

[progvp]

On latest version of mail-check and Jenkins 2.121.3, Ubuntu server 18.04 LTS I get this error:

`org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during class generation: Method code too large!

Can you help me with that?

Looks like you hit a Open bug in Jenkins - https://issues.jenkins-ci.org/browse/JENKINS-37984. Either wait for a fix or try improving the Stages by streamlining some of the bash commands that can be wrapped into shell scripts and call within each stage.

Hi, as part of our journey from a monolithic architecture to microservices we are stripping out all of the build and test steps from the monolithic pipeline. The end goal is for it to just assemble the microservice artifacts and terraform modules in the pipeline for each environment, removing all build and test steps, this should improve things over the next couple of releases. I'm surprised you have hit this bug as when we do, we refactor some of the jenkinsfile, so you must be hitting it at a different level from us. I'll raise a ticket to refactor it some more for the next release to give more headroom on the size.
