SBT Plugins: How and Why

In this talk, we’ll learn about the inner workings of SBT by walking through the creation of a simple plugin.In large projects and/or organisations, building the project involves more than just compiling the code.

Using plugins we can customise SBT to automate almost any task imaginable: testing, publishing, reporting, generating documentation, code analysis, and so on.

However, we might wonder what we would do on the fateful day when the plugin we are looking for doesn’t exist and we have to write it ourselves.

This talk will give us a headstart on such a day.

We will start by lifting the lid on some existing SBT plugins, learning more about how they are constructed and how they work.

Then, we will take control and develop a simple one of our own.

We’ll see how plugins interact with the build and in the process learn more about SBT in general, demystifying this sometimes maligned tool.
