It was an experiment to let plugins be written in ruby but still get integrated into the main Java Virtual Machine runtime with help of JRuby. A similar extension was made to allow plugins to be written in Python but still integrated into the Java Virtual Machine with Jython. Over the years though, the experiments are no longer being...

This is a guest post by Liam Newman, Technical Evangelist at CloudBees. Declare Your Pipelines! Declarative Pipeline 1.0 is here!

This doesn’t mean that we’re done and that you can go forth and write pure ruby plugins…​ not by any stretch of the imagination. Instead, what it does mean, is that the Jenkins mainline is much more friendly to runtime analysis of classes with which it is not familiar. The problem When analyzing...

You know that the night is going to be productive whenever @kohsukekawa shows up, and last night was no exception. We talked about problems on the horizon, potential solutions, and then I spent the last half hour ripping a bit of code. The truth of the matter is that most of the changes that have to be done to Jenkins core have already been made,...
