Hi Juan,

I have gone through this post and very much excited to implement it in part of my projects.

Everything works super... till one point.

Is it possible to make standardPipeline.groovy return some value(A collection Object) and capture that in the Jenkinsfile and pass it as an argument to another groovy script which is in a shared library?



Hi Prasanth,

Sorry for my late reply. To be honest, I have not idea about that. That was not needed in my case. You can pass parameters from your Jenkinsfile to the shared library but not sure about the other way around. Maybe if elaborate your specific need, we find another way to do it without that.



Sorry for my reply as well...

I was trying to do some modifications to an class object in a library function and explicitly returned the same object to use in the pipeline in the later stages and I could do it with defining the appropriate return type(though def works).

Now it works as expected.


Hi Juan,

Thanks a lot for this post, really simple and straight forward.

I have a question related to this, as relying much on the shared library is an amazing way for having a very simple Jenkinsfile in each of my services which is cool, but that means any change in this shared library can break everything.

How to test the pipeline "shared library" before merging any change in my master branch that is called by every other service calling this pipeline, in another way how to test any changes before applying them to void breaking everything?

I tried to follow the JenkinsPipelineUnit on github but I really didn't get it well, can you explain it if you have done this before?

Thanks a lot


Hi Abdel,
What I usually do is to add my changes in a new brach of the shared library. Then I take one project and I modify its jenkinsfile to use that new branch. You can do that like that:

@library("your-library-name@BRANCH_NAME") _

After testing that everything works ok, I merge the library changes in master.

Would that work for you?


HI Juan,

Thanks again for your reply, but this is actually what I do in the mean time passing my own branch of the shared library repo, but seems to be very manual to us especially wish a really complex pipeline.

What I meant in my question is can we do any sort of unittest to the pipeline before merging to the shared library master branch

Things like cucumber, maven ...etc have you done any similar testing before for the sharedlibrary repo before as I can see your way is very manual testing and I wish if you had done any automated testing for the pipeline with the shared library.

Again Thanks a lot Juan

Hi Abdel,

No, I do not do any automated tests for the pipeline code itself. If you find a convenient way to do it, I’d love to know more. I think there is something about testing the pipeline code in the following video. Here is the link in case it helps:


This is great, thank you. I've been using Jenkins for a while but never got very far into it past builds and tests, so now I'm going back over everything using Jenkinsfiles and deploy stages and this has been very helpful.


Thanks James, I am glad you found this useful. I will encourage you to try using Jenkinsfiles. Easy to setup and much more comfortable to maintain.


Do you have an idea how to reach the shared libraries directory structure if I want to keep it in specific directories in my repo?
Like if I put my vars and src folders not to the repo root, but in somewhere deeper:



Sorry, I have no idea whether that is possible. I did not see anything about that in the jenkins docs. Let us know if you figure out how to do it.


Hi Juan,

I was trying to implement the same concept into my shared library activities to handle repetition of code.

I am using Jenkins v2.105 and I see some problems when I shifted my stage definition into a shared-library call as below:

Before Update:

ln#01 pipeline {
ln#02   stages {
ln#03     stage('1') {
ln#04       println "I am in stage 1"
ln#05     }
ln#07     stage('2') {
ln#08       println "I am in stage 2"
ln#09     }
ln#10   }
ln#11 }

After Update:

ln#01 pipeline {
ln#02   stages {
ln#03     stage('1') {
ln#04       println "I am in stage 1"
ln#05     }
ln#07     dynamicStage{
ln#08      param = '2'
ln#09     }
ln#10   }
ln#11 }

ln#01 def call(body) {
ln#02   def config = [:]
ln#03   body.resolveStrategy = Closure.DELEGATE_FIRST
ln#04   body.delegate = config
ln#05   body()
ln#07   stage('Dynamic Stage') {
ln#08     println "I am in stage ${config.param}"
ln#09   }
ln#11 }

Expected Behaviour:

I am in stage 1
I am in stage 2

Execution Result:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 07: Expected a stage @ line 07, column [ColumnNumber].
       dynamicStage {

Is it something that the Jenkins v2.105 doesn't support this?


Any Luck on the shared library that you have implemented?


Heya. I followed your example but when I try to run this I get

"groovy.lang.MissingPropertyException: No such property: qools for class: groovy.lang.Binding"

Where "qools" is in the name of several of my classes since that's the project name but I have no properties defined that are named or have the value "qools" anywhere in them. Very strange.


Hi Chris,

Where do you use "qools"? Inside the Jenkinsfile or in your library? Is it maybe the name of your library? If you could send me an example of the code where "qools" appears, I could help you more.

Did you also try the basic examples on this blog post?


Hi Juan!
Had a question about what types of variables can be passed into the standardPipeline.
I've been able to pass strings and booleans but am having trouble passing in arrays. Do you know if this is possible?



Hi Brian,

I never tried passing arrays, so I do not know whether that is possible. Sorry that I cannot help with that.


Nice post!

There is a small error in the first example of pipeline.

Missing one " in:

ServerDomain = "Project1 Server Domain

im trying to run the sample from groovy sandbaox and got an error

java.lang.NoSuchMethodError: No such DSL method 'standardPipeline' found among steps

any idea here ?



Hi David,

If you get this error, I would say that the library repo is working but it does not find the file standardPipeline.groovy. Can you re-check that your shared library is called standardPipeline.groovy and it is inside vars folder as in this example?

I also updated the post because I noticed some formatting issues. You might also want to review the "Jenkins Configuration" section to ensure that is correct.


Thanks for this excellent post.

I'm curious whether you find BlueOcean stable yet? starting now a new Jenkins project and having thoughts whether to use scripted pipeline or BlueOcean


Hi Yoni,

I am glad you liked the post. Yes, BlueOcean is quite stable now. We have been using it for a while and did not have any mayor issues. Scripted pipeline and BlueOcean are 2 things that work together though. BlueOcean is more like a template that make the Jenkins Pipeline interface prettier, whereas you still need the scripted Pipeline configuration. So regarding your thoughts, the answers is easy: Scripted Pipeline + BlueOcean template.


Great, is there any way this can be implemented for Dotnet projects? Any examples that will be a great help.
