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.

Apache Ant features 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. Set PATH environment variable by appending path of ANT. Build a basic ANT script and run from command prompt.


Running and checking whether Ant is installed in the system .


Writing build.xml file in Notepad


Running build.xml file in command prompt


Running hello.xml file


Executing hello.xml in command prompt


Writing Second target in hello.xml


Executing Second target of hello.xml in command prompt


Executing build.xml in eclipse


Executing run target


Executing run target in eclipse


Executing second run target in eclipse


Sample Ant build.xml


Apache Maven

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.


Apache Maven features 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.


Apache Maven Installation Download latest version of maven and unzip the folder. Copy the bin path. Go to environment variables find path variable and edit and paste the bin path. Create a new variable as Maven_Home and paste the path of Maven. And the Java_Home should contain path of the java. Go to command prompt and check whether maven is installed or not by typing mvn –version.


Apache Maven Installation


Downloading jars from command prompt


Apache Maven Installation

First we need to add all the dependencies to pom.xml file.Then run,

mvn compile is a command to get dependencies jar from internetIt will download Jars from internet based on pom.xml file.

mvn installCommand for executing test script from command prompt.

Apache Ant VS Maven

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.


Apache Ant VS Maven

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.
