Apache Ant Hello World

To create a simple hello world project, we are using Eclipse IDE and the project require the below steps.

Create a Java Project
Create a Java File
Create an XML File
Create a Folder
Run as Ant Build

Java Project

Create a project by selecting Java project from the File menu and provide it's name.

Java File

Create a Java class by providing it's name Hello, see the below example.

XML File

Create an XML File by providing it's name build. Build is a default name but we can set other name also.

Create a Folder

Create a folder to organize compiled Java class files. The folder can be anything, here we have created a test folder.

Project Structure

After creating all the above files, our project should look like the below.

In this project, Java and XML file contains the below code to display Hello World message.

// Hello.Java

package com.javatpoint;
public class Hello {
	public static void main(String[] args) {
		System.out.println("Hello Javatpoint");
	}
}

// build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="java-ant project" default="run">
	<target name="run" depends="compile">
		<java classname = "com.javatpoint.Hello">
			<classpath path="test"></classpath>
		</java>
	</target>
	<target name="compile">
		<javac includeantruntime="false" srcdir="./src" destdir = "test"></javac>
	</target>
</project>

Run Project

To run the project, right click in the build.xml file and select Run as → Ant Build. After running that, it shows the output in a specific format, see the below.
