After a long flight, I think the first version of Buck support is
ready. The final commit in the series is:

  https://git.eclipse.org/r/17995

Please fetch and test. Build produces JARs, JUnit tests run and pass,
and an Eclipse uber-project can be generated.

is there a way to debug a test run by buck ? On my Mac I get the following

test failure which I'd like to debug (when run using Maven or Eclipse it doesn't fail),

I tried to debug

export BUCK_DEBUG_MODE="yes"

and attached the debugger on port 8888 with a breakpoint on the first line of the failing test

but it seems the test doesn't run in the process attached to the debugger.
