When it comes to generating command-line scripts for Java applications, Maven "appassembler" plugin comes handy. Its "assemble" goal does all the maven magic, i.e. searching the dependencies used for creating the Java application, adding them into the classpath of resultant script and finally copying all relevant jars to a single place. It was all working very nicely until I stumbled across the problem of long classpaths in the Windows OS.

Irrespective of whether you use DOS prompt or cygwin, Windows limits the length of environment variables. Though there are various options to overcome this problem using Java 6 wildcard classpath, mapping the path to some drive etc, they all look like workarounds to me as problem can recur again anytime.
