2. Preparing a build area
3. Compiling the source code
4. Build the compiled code to executable code

Q. What is the differences between Ant and Maven
A.1. Maven is widely preferred than Ant. Ant is an older tool.
2. Ant doesn't come with formal conventions such as a common project directory. Maven consists of conventions.
