Many modern Java development environments also feature Ant support.Īnt uses build files, which are simply XML files that tell the Ant program what to do. It’s rapidly become the de-facto build tool for J2EE projects, so for developers, it’s certainly worth becoming familiar with the basics of Ant, at the very least.

About AntĪnt is an open-source Java-based build tool from the Apache Software Foundation. What’s needed is Another Neat Tool in the developer’s armoury. It’s no good to rely on some harangued colleague typing a complicated command in a Command Prompt window to invoke the Java compiler with a classpath as long as this article.

These are the reasons why Microsoft builds the five gigabytes of Windows source code every day, even though it takes twelve hours - on very powerful and expensive servers - to do so.Īs you might imagine, in order to be able to perform daily builds, the build process has to be automatic and repeatable. The daily build becomes the heartbeat of the project. If something’s broken, it gets noticed faster, so it gets fixed faster. If you build your software every day then it acts as a barometer, showing the state of the project. (This instructions mostly comes from Ashley J.One of the principles of good software engineering is the daily build. Follow the comments in the example build.xml, and customize it for your Pleas first make sure Tomcat is started, and then You can start with the example build.xml providedīy Tomcat to create your own. The only thing should be notified is that there is a set of properties Tomcat, the way you use Ant to compile projects is not different from the basicĪnt.

You could refer to this property laterĪnywhere in this build file using $.ĥ-7 a target element. The nameĪttribute specifies the name of the property and the value attribute specifies User-definable variables available for use within an Ant build file. If this is omitted the parent directory of the build file will be used.ģ-4 the property element allows the declaration of properties which are like The 'basedir' is the base directory from which any relative directories used within the Ant build file are referenced from.
