Any parameters provided as part of the input submission will be available in the environment for the rest of the stage. parseText(file) def data = details. All files are located in var directory. It allows for dynamic job execution based on build parameters and conditions. STAGE_NAME it returns null. But was still hoping to be wrong. Check Blue Ocean UI and see that the stage injected that way does not provide the same features as a regular declarative stage. The axis directives inside an exclude generate a set of combinations (similar to generating the matrix cells). jenkins def class PipelineHelper { def steps PipelineHelper(steps) { this. call, if a custom stage was provided, tack it on to the end of the pipeline, or perhaps between two (known) stages, and run it Something like this project-a/Jenkinsfile After a lot of surfing I did reach that conclusion, that maybe post is not applicable inside script.

UPDATE I have a simple pipeline where I want to receive in parameters multiple choices from a file. I edited my answer so that inputResult is accessible from other steps and stages. I've also tried: ${STAGE_NAME} and${env. In the below screenshot, I don't want the steps Approve K8s Dev Deployment and Create and Deploy to k8s Dev Environment to show in the pipeline stage view as I am skipping these based on my branch names. Groovy’s expressive syntax and powerful features, such as closures, metaprogramming, and dynamic typing, provide developers with a versatile tool for defining and Hi, I figured out the same after a few failing attempts. I tried for for loop after the parallel keyword, but groovy was complaining that he wants a stage declaration at this point. xml output of that job parameter: <hudson. Each of them will have stages before for allocation and preparation. Groovy is a dynamic scripting language for the Java Virtual Machine (JVM) that is well-suited for scripting in buildProject. If you want to have a parameter that's available on all the stages, you can define a parameter outside of the stage, i. Can it be done in Jenkins pipeline? For example, after stage one, users can have a choice to select lint. } sections inside a node for some reasons the workflow stage chart and Blu Ocean get confused.
