Class Raven::GemWrapTask
In: lib/raven/java_tasks.rb
Parent: Rake::Task

Wraps a jar file around a Gem. Useful for distributing it around. The jar is taken from the target directory. You must at least specify version to produce the Gem. The artifact name and group name default to the current directory name and its parent directory name respectively. Convenient if you follow the classic project/module directory structure. Otherwise, just set the artifact and project to any value that suits you.
