Apache Ant/Getting Started/Hello World
Hello World in Ant
editCreate a directory "My Project". Use a text editor such as Kate, Gedit or Notepad to create a file called build.xml within directory "My Project":
<?xml version="1.0"?>
<project name="My Project" default="hello">
<target name="hello">
<echo>Hello World!</echo>
</target>
</project>
The first line in the file is flush left (no indentation). It tells ant that this is an XML file:
<?xml version="1.0"?>
The next line names the (required) project "My Project" and its default target "hello":
<project name="My Project" default="hello">
The central three lines name and define the only target ("hello") and task ("echo") in the file:
<target name="hello"> <echo>Hello World!</echo> </target>
You can now open a shell and cd to the "My Project" directory you created and type "ant"
