There is partial fix for this for Declarative pipelines in pipeline-model-definition-plugin v1.4.0 and later, significantly improved in v1.8.4. Due to the extent to which it change how pipelines are executed it is turned off by default. It can be turned on by setting a JVM property (either on the command-line or in Jenkins script console):
org.jenkinsci.plugins.pipeline.modeldefinition.parser.RuntimeASTTransformer.SCRIPT_SPLITTING_TRANSFORMATION=true
As noted, this still works best with a Jenkinsfile with pipeline directive as the only root item in the file.
Since v1.8.2 this workaround reports an informative error for pipelines using `def` variables before the pipeline directive. Add a @Field annotation to those declaration.
This workaround generally does NOT work if the pipeline directive inside a shared library method. If this is a scenario you want, please come join the pipeline authoring SIG and we can discuss.
Please give it a try and provide feedback.
Hi,
We are getting below error in Pipeline which has some 495 lines of groovy code. Initially we assumed that one of our methods has an issue but once we remove any 30-40 lines of Pipeline groovy, this issue is not coming.
Can you please suggest a quick workaround. It's a blocker for us.

I've run into the same problem. I have a large (200+kb) pipeline script that is generated from our legacy build specification language.
My generated code is broken up into stages, with each stage running a potentially large parallel pipeline operation, where each platform of a given target is built.
After some googling about the underlying cause, I attempted to break it up by having each stage be defined as a method and calling the method rather than just having all the code in one giant block, but it didn't help.
As this will impact a lot of people trying to migrate to the Jenkins pipeline, and may make them throw up their hands due to the error being vague and unhelpful (which I realize is not the fault of Jenkins, but the underlying Java/Groovy architecture), it might be good to have some specific guides on how to deal with this.
