How to compile?

When I try to run the RSBot the screen stays white.
I found out that I had to compile the files. So I searched the map for the word Compile. One of the search results is Compile all. I tried to run it, a window pops up and it says in the last line: Could not find the main class: rsbot.bash.compiler. Program will exit.
What do I have to do?

Update RSBot/Download newest Java.
Could help =)

 

^^ do what this guy says ^^

 

If the Compiler cannot find the main class, then download rsbot again, because compile.class is the ONLY .class file that rsbot comes with.
