For all homebuilders using the develop branch: the submodule for e2openplugins has been removed.
This means you need to run:
git submodule deinit -f meta-openpli/recipes-openpli/e2openplugins
in the root of your local clone before doing a pull !
If you do it after, you'll end up with an empty e2openplugins directory, and you need to do a
git reset
to fix that.
After this, ./meta-openpli/recipes-openpli/e2openplugins should be a normal directory, not a git repo anymore.
