The Ant Script for BlackBerry

Our Ant script was written following the Makefile in Listing 1. Our script provides build tasks to clean directories, and build our application. Our Ant script consist of the following major tasks:

• Common build tasks for MIDP applications - this provides tasks such as clean, init, compile, preverify, prepare the JAD and MANIFEST files, and prepare the JAR file.
• BlackBerry-specific build tasks - this provides task to generate the BlackBerry-specific files.

Separating the build into these steps allows us to easily create both a JAD/JAR and COD files. Note how the common build tasks generate a MANIFEST, JAD, and JAR files, and how the generated JAD and JAR files are used as input into the BlackBerry-specific build tasks.

Listing 3 shows the finished Ant script:
