> We have a simple {{JarFileCreator}}, which allows to add classes to a JAR file as follows:
> {code:java}
> JarFileCreator jfc = new JarFileCreator(jarFile);
> jfc.addClass(X.class);
> jfc.addClass(Y.class);
> jfc.createJarFile();
> {code}
> The created file can then be used with the remote execution environment, which requires a JAR file to ship.
> I propose the following improvement: use [ASM|http://asm.ow2.org/] to extract all dependencies and add create the JAR file automatically.
> There is an [old tutorial|http://asm.ow2.org/doc/tutorial-asm-2.0.html] (for ASM 2), which implements a {{DependencyVisitor}}. Unfortuneately the code does not directly work with ASM 5, but it should be a good starting point.
