Maven and ANT

1. Java Build tools : Ant and Maven
 Ant was the first among “modern” build tools.
 It was released in 2000 and in a short period of time became the most popular build
tool for Java projects.
 It is very easy to learn thus allowing anyone to start using it without any special
preparation.
 It is based on procedural programming idea.
 Maven was released in 2004. Its goal was to improve upon some of the problems
developers were facing when using Ant.

 Ant doesn’t have formal conventions like a common project directory structure or
default behavior.
 You have to tell Ant exactly where to find the source and where to put the output.
 Ant is procedural.
You have to tell Ant exactly what to do and when to do it.

Getting started with Ant
 Download and unzip the latest version of ANT.
 You should have installed Java and set up path of JAVA_HOME.

Apache Maven is a open source build testing tool. It will check the
compilation issue in entire framework based on the concept of a
project object model (POM), Maven can manage project's build,
reporting and documentation.

 Maven has conventions.
It knows where your source code is because you followed the convention. Maven’s
Compiler plugin put the bytecode in target/classes, and it produces a JAR file in
target.
 Maven is declarative.
All you need to do is create a pom.xml file and put your source in the default
directory. Maven will take care of the rest.

ANT,
doesn't have formal conventions like a common project directory structure,
you have to tell Ant exactly where to find the source and where to put the
output.
is procedural, you have to tell Ant exactly what to do and when to do it. You
had to tell it to compile, then copy, then compress.
doesn't have a lifecycle, you had to define goals and goal dependencies. You
had to attach a sequence of tasks to each goal/target manually.

Maven,
 has conventions, it already knew where your source code was because you followed
the convention. It put the bytecode in target/classes, and it produced a JAR file in
target.
 is declarative. All you need to do is create a pom.xml file and put your source in the
default directory. Maven will take care of the rest.
