Chapter 10. Setting Up Your Development Environment
If you plan to develop code for Drill, you will need to set up a Java development environment. You will find it convenient to create two kinds of projects. The first is a clone of the Drill source code. Often you will need to reference Drill code to find how to accomplish a task.
The next two chapters describe how to create user-defined functions and format plug-ins. It is often easiest to debug your custom code as part of the Drill build so that you can get rapid edit-compile-debug cycles, create unit tests, and so on. Later, when your code is stable, you have the option to package the code into the second kind of project: an extension project separate from Drill.
Drill makes use of Maven for the build-and-test process. A detailed description of Maven operations is beyond the scope of this book, but we do cover how to install it for Drill development.
