public class OneJAR

extends Object

A dependency aware JAR packager. Usage:
java -cp classPath org.sourceforge.jxutil.app.OneJAR jarFile [classes...] [-m manifest-file] When used without classes the jarFile is modified to contain a closure of dependencies that can be resolved to classes in the classPath. With classes, the jarFile is created to additionally contain the classes with the dependencies resolved.
