Do you know that you can unit test your Jenkins pipeline code? Have you ever used linter to validate the syntax of the Jenkinsfile? Do you use input step with a long timeout that blocks the executor and you don’t know how to improve? I answer those three questions (and two more) in the following YouTube video.

The declarative Jenkins Pipeline allows us to define timeout either at the pipeline level or the specific stage. This feature prevents Jenkins’s job from getting stuck. However, in some cases, we want to accept that one stage may timeout, but we want to keep the remaining stages running.

If you read this blog post, there is a high chance you’re looking for information about practical differences between scripted and declarative pipeline, correct? You couldn’t find a better place then. I’m going to show you the four most practical differences between those two. Stay with me for a few minutes and enjoy the ride!

In one of the latest blog posts, I have shown you how you can build a Docker image with Java and Maven installed with the SDKMAN! command-line tool. Today I would like to continue the topic and show you, how you can compile your project using two different Java versions in parallel.

I was using Travis CI to execute 271 builds and deployments of this blog. Last Friday, I decided to experiment with CircleCI and see if this could be a viable alternative to my current solution. In this blog post, I explain why I decided to switch, and how to set up CircleCI to deploy Hexo blog to the GitHub Pages without much hustle.

In the last article, I have shown you how you can build a docker image for Jenkins Pipeline using SDKMAN! command-line tool. Today I will show you how you can build multiple different docker images using parallelized Jenkins Pipeline.

A few days ago, I was struggling with some Docker images I use in my Jenkins CI environment. I run some Jenkins Pipelines, and I like to define build environment as code using custom Docker images. Everything was fine until I had to consider running different Java or Maven versions. I decided to use one of my favorite command-line tools - SDKMAN!, to build a highly configurable build environment.

Have you run into troubles when you started using Jenkins Environment Variables in your Jenkinsfile? In this blog post, I show you how to use environment variables, how to override them, how to work with boolean values, and how to store a result of sh step in the env variable. After reading this article, Jenkins env variables won’t surprise you anymore!
