[yocto] local file update vs rebuild

[Takashi Matsuzawa]

Hello.
I am uncertain about do_clean behavior with local files.


Say, I have local files referred by my recipe, and I have made changes to the files referred.
(Note, there is no change in my xxxx.bb file itself.)


>SRC_URI += "file://src/*;subdir=local"


What makes those changed files reflected to the build?
Do I need do_cleanall?  do_cleansstate or maybe do_clean is enough?


According to the document


> do_clean
> do_unpack task forward (i.e. do_unpack, do_configure, do_compile, do_install, and do_package).
> if no changes have been made and the recipe is rebuilt after cleaning, output files are simply restored from the sstate cache. 


I want to avoid doing do_cleanall often, and I would like to tell bitbake that my recipe needs rebuild at the same time not rebuilding others.
But at the same time I want to avoid building my single explicity.
I just want to build the image name as target.
