Ant Execute Java Program
A defined process is one of the most necessary but often least-used tools in software development. It is by nature an overhead task that accompanies a development effort. A defined build process ensures that the software in your development project is built in the exact same manner each time a build is executed. As the build process becomes more complex - for example, with EJB builds or additional tasks - it becomes more necessary to achieve such standardization.
You should establish, document, and automate the exact series of steps as much as possible. Why do I need a defined build process?A defined build process is an essential part of any development cycle because it helps close the gap between the development, integration, test, and production environments. A build process alone will speed the migration of software from one environment to another. It also removes many issues related to compilation, classpath, or properties that cost many projects time and money.
Ant Clean Build
What is Ant?Ant is a platform-independent scripting tool that lets you construct your build scripts in much the same fashion as the 'make' tool in C or C. You can use a large number of built-in tasks in Ant without any customization. Some of the most important tasks are shown in the following table but explained in more detail in the example that follows. Here are some useful commands that are built in the Ant distribution.
