So that did fix the initial issue, it's not rebuilding everything every time now.
Now I'm noticing that if I change options in the
pio cicommand,platformio.iniis not updated to reflect those.So for example, if I pass
--project-option="build_flags = -Dsomething=42"and then pass--project-option="build_flags = -Dsomething=43", platformio.ini is not updated.ivankravets commentedon Apr 1, 2019
If you update
platformio.ini, we will recompile the whole project. So, there is no sense in--keep-build-dir.There are a few workarounds:
pio ci --exclude=platformio.ini- means, we will remove previouspio ci --project-conf /path/to/custom/platformio.ini
