How to set a constant in Jenkins DSL

 

Working with the Jenkins DSL configuration is quite easy. But we need to remember about best practices and do some work for ourselves. Just to simplify out live. One of these things is creating good code. We should extract repeating code blocks and use them in different places. Let’s assume, that we want to create granular permissions – Alice has permissions only for Job A, but Bob has permissions for both, Job A and Job B. As you see, we have now two jobs and two users. But we don’t know when we will have to add more users. And Continue reading

Jenkins DSL Authorization Matrix loop

Jenkins Job DSL Playground – how it works

 

Working with Jenkins Job DSL code sometimes is a pain in the neck. Especially if you have very big and complex scripts. You can make a mistake very quickly, so it would be great if there could be a way to test your code before the seed deployment. Of course, you can test your DSL scripts outside of Jenkins, but sometimes you don’t need to run the whole bunch of tests, right? You just want to check only the small part of your code… What if I tell you that you can do that? Ladies and gentleman, let me introduce Continue reading

Jenkins – unable to resolve class utilities.MyUtilities

 

It’s more than likely, you start trying to import external classes/files if you use Jenkins Job DSL Plugin. When your jobs grow to tens or hundreds of projects, some code will be common in some places. So, you will read the documentation, check the community forums, try to find out the best way to simplify your life. And you find it. You will find very quickly, that you can import classes from external files. Jenkins DSL uses Groovy, and Groovy is based on Java, after all, so it’s not a surprise.

Variable as a Groovy map key

 

Maps are the structures which can be very helpful. I’m not a developer, so I’m sure that many of you will take this post with a grain of salt. Even though, If you use Jenkins, you can face the same problem I faced some time ago. My experience with Groovy is limited to Jenkins job DSL configuration, but I always try to create a configuration as simple as possible. So sometimes my scripts are full of loops, conditionals, and variables. In one of my job, I tried to use a map and create a nested loop, where one of the Continue reading
