If jgrasstools is using the geotools process api in theory it should be 
a matter of adding a maven dependency to the module.
In practice even if you're already there some debugging to align either
side to match will most likely be necessary.

I believe I'm interested, it's just hard to find the time. But if
it's really just a matter of adding a dependency I can give it a
spin this Friday.

What is required to use those tools?
