Why Build Tools Matter for a Well-Grounded Developer

From The Well-Grounded Java Developer by Benjamin Evans, Jason Clark, and Martijn Verburg

The JDK ships with a compiler to turn Java source code into class files. Despite that fact, few projects of any size rely just on javac. Build tools are the norm for a number of reasons:

Automating tedious operations
Managing dependencies
Ensuring consistency between developers

Understanding what these tools aim to solve, digging below the surface of how they get their job done, and understanding the differences between them – and how to extend them – will pay off for the well-grounded developer.
