Hey Rhett,
A big thanks for your support, the custom layout idea is now much clearer
for me. Once I changed the custom layout to include "src" as you suggested
things started looking a little more healthy but it's now unclear where the
compiled output is going, if it is being created at all. Here is my full
custom layout specification:
-----------
michel_layout = Layout.new
michel_layout[:source, :main, :java] = 'src'
michel_layout[:source, :test] = 'test'
michel_layout[:target, :main] = 'bin'
michel_layout[:target, :test] = 'bin'
-----------
I expected that I would end up with a bunch of .class files in the bin
directory but that doesn't happen as you can see below.
-----------

----------
I noticed the line "Invoke Jamie's Robot:compile (first_time, not_needed)".
Does the "not needed" imply that buldr thinks that the compile is already
up to date and therefore does not need to be done this time round? The bin
directory does not exist, so I would expect a full re-compile.
Kind regards,
Mark
