Classpath package is missing


I'm trying to install jamvm package on my WRT1200ac router, but it seem that classpath package is missing...
How can I solve this?

Best regards.

That package doesn't even exist:

It sure does ("wrong" repo however) but it fails on the builtbots because they don't have Java installed

You need to compile it yourself

That's what I thought... Unfortunately, I don't know how to compile, never mind...
