Yes, I'm kinda sorry that I posted that question.  It's always like that, 
if I didn't post it then I would've spent a long time figuring it out, 
but if I post then I often get it fixed fairly quickly!

Please do comment on the "right" way to do this, keeping in mind that 
it's partly a way of learning ruby:



thufir@arrakis:~/sun_tutorial$ 
thufir@arrakis:~/sun_tutorial$ cat build.rb 
require 'clean'
require 'compile'
require 'run'


clean
compile
run
thufir@arrakis:~/sun_tutorial$ 
thufir@arrakis:~/sun_tutorial$ cat clean.rb 
def clean
        puts "cleaning all class files..."

        system("rm *.class -fv")
end
thufir@arrakis:~/sun_tutorial$ 
thufir@arrakis:~/sun_tutorial$ cat compile.rb 
def compile
        puts "compiling..."
        system("javac HelloWorldApp.java")
end
thufir@arrakis:~/sun_tutorial$ 
thufir@arrakis:~/sun_tutorial$ cat run.rb 
def run
        puts "running..."
        system("java HelloWorldApp")
end
thufir@arrakis:~/sun_tutorial$ 
thufir@arrakis:~/sun_tutorial$ ruby build.rb 
cleaning all class files...
removed `HelloWorldApp.class'
compiling...
running...
Hello World!
thufir@arrakis:~/sun_tutorial$ 






thanks,
