MonkeyCI uses the Clojure CLI in order to execute the build scripts. This CLI allows to configure dependencies to include other libraries in your code, and so it's also possible to do this in your build scripts. These dependencies are configured in a file called deps.edn which should be put next to your build.clj, in the .monkeyci/ directory. Although the CLI provides a lot of functionality with this file, we use it mainly to declare dependencies, like so:

Often it is desirable to receive notifications on various build events, for example when a build is finished, or when a new image or library version has been published.

Plugins are a way to extend MonkeyCI's functionality. Basically, they are no more than regular Clojure libraries that you can include in your build using the deps.edn. In order to use a plugin, you have to require or use the relevant namespace in your build script, and then invoke the provided functions. There is no magic, it's simple to use!
