<jar>

The <jar> task gives you the ability to create JAR files, which is useful when putting together distributions, backups, and so on. It is an implicit fileset that produces a JAR file from the files included in the set. The nested elements help to refine the set even further, as well as enabling you to specify the contents of the META-INF directory. Table 4.42 details the attributes of the task that makes creating JARs easy.
