Yes ofcourse!

the attach is my test project, just according the bitbake manual's 
printhello example.

my bitbake was cloned from 'git://git.openembedded.org/bitbake'
and using revision id was: 309f5907a3661821e041ed14645b5d165007b058

Run 'bitbake printhello' firstime the output is:

$ bitbake printhello
Parsing recipes: 100% 
|##########################################################################################################| 
Time: 00:00:00
Parsing of 1 .bb files complete (0 cached, 1 parsed). 1 targets, 0 
skipped, 0 masked, 0 errors.
NOTE: Resolving any missing task queue dependencies
NOTE: Preparing RunQueue
NOTE: Executing RunQueue Tasks
NOTE: Tasks Summary: Attempted 1 tasks of which 1 didn't need to be 
rerun and all succeeded.

Then edit do_build task, run 'bitbake printhello' secondtime the output is:
$ bitbake printhello
Parsing recipes: 100%
