Restart from stage

[unli...@gmail.com]

Are there any examples of the implementation of running a pipeline from a particular stage? I need to set in the pipeline parameters to make it run on a specific node and from a specific stage. If there are no questions with the first one, what are the easiest options to pass <stage name> from which to run the pipelines, skipping the previous ones?
Something similar I found here but it's not enough for me to implement this task:

https://issues.jenkins.io/browse/JENKINS-52391

Thanks!

Hi what-ever-is-your-name-:-)

I use the "when" block to run only specific stages depending on the
parameters: https://www.jenkins.io/doc/book/pipeline/syntax/#when

I hope that fits your case too.

Cheers,

Gianluca.

Thanks, Gianluca.

Your professional help, as always, is very operational and useful!
Thanks to you, I have implemented the ability to run from any Stage, but I would also like to form in "Active Choices Reactive Parameter" plugin automatic list from the names of Stages {}, which I have in PiPleine. Are there ready examples of code to obtain a list of names of all Stages from code pipeline (to select the stage I need before building the pipeline) ?

Hi,

I use the following code to walk through all stages of the pipeline for
a different reason but it could be an hint for you to achieve your goal:

WorkflowRun run = prevBuild.getRawBuild()
NodeGraphBuilder graphBuilder =
NodeGraphBuilder.NodeGraphBuilderFactory.getInstance(run);
 def flowNodes = graphBuilder.getPipelineNodes()

 for (Iterator iterator = flowNodes.iterator(); iterator.hasNext();) {
        def node = iterator.next()
        if (node.getDisplayName() == stageName) {
            return node.getStatus().getResult() == BlueRunResult.SUCCESS
        }
 }

A stage is a pipeline node, but there are nodes that are not stages. So,
you probably need to dig into internal code to find out how to identify
only the stages.

Cheers,

Gianluca.
