The next step is to compile all the classes in the src directory and place them in the build/classes directory. To do this first you need to add all the lib files inside the "WebContent/WEB-INF/lib" directory to the classpath.
The path we created earlier will be refered here using the <classpath> element.
Now we can create the war file using the war task. To create the war file you need to specify the web directory, lib directory and the classes directory. The destfile attribute specifies the war file location and the webxml attribute specifies the web.xml file location.
