When you are working in a development environment, your system might be configured to read from a development database instance running on your local machine, whereas in production your system is configured to read from the production database. Maven allows you to define any number of build environments (build profiles) that can override any of the settings in the pom.xml. You can configure your application to read from your local, development instance of a database in your “development” profile, and you can configure it to read from the production database in the “production” profile. Profiles can also be activated by the environment and platform; you can customize a build to run differently depending on the operating system or the installed JDK version. Before we talk about using and configuring Maven profiles, we need to define the concept of “build portability.”

What Is Build Portability?
