| <h1>Ant buildfiles as project builders</h1> |
| |
| <p>Our second practical example of using Ant buildfiles in Eclipse |
| is a 'project builder'. This is an Ant buildfile that has been designated to |
| run whenever a project is built. The uses for such a buildfile are many:</p> |
| <ul> |
| <li>Generate a <code>.jar</code> file containing class files from your project</li> |
| <li>Perform some type of pre- or post-build processing on source or binary files |
| in your project. For example: |
| <ul> |
| <li>Pre-processing source files to instrument them for performance analysis</li> |
| <li>Obfuscating binary files to prevent reverse engineering</li> |
| </ul> |
| </li> |
| <li>Copy class files to some location (for instance, on a network)</li> |
| </ul> |
| <p>For this example, we will create an Ant buildfile that creates a <code>.jar</code> archive |
| of the class files in a project. Note that this is similar to the example in |
| the last chapter, in which we used an Ant buildfile to generate <code>.jar</code> files for |
| an Eclipse plug-in. This example differs in that it works for any Eclipse project, |
| whether or not it is also an Eclipse plug-in. |
