Lots of ExpansionError exceptions since yocto 2.1

[AlgorithMan-de]

Since yocto 2.1, the getVar function in bitbake/lib/bb/data_smart.py doesn't have a default value for the parameter 'expand' anymore. Because of that, meta-openembedded layers throw a lot of ExpansionError exceptions, saying getVar() missing 1 required positional argument: 'expand'.

It wasn't changed in 2.1, but in 2.3 and master is already fixed. Read README in top directory and use ML.

I see these errors in a fresh 2.2 checkout (git clone -b morty git://git.yoctoproject.org/poky.git as suggested on https://www.yoctoproject.org/downloads) with a fresh checkout of git://git.openembedded.org/meta-openembedded master as referenced on https://layers.openembedded.org and the toplevel README only says

Collection of layers for the OE-core universe
Please see the respective READMEs in the layer subdirectories

Maybe git://git.openembedded.org/meta-openembedded isn't up to date?

You need to use compatible branches, so use morty branch of meta-openembedded instead of master.

@shr-project I tried with compatible branches i.e morty for meta-openembedded but it still throws in that error. Any further help?

@JOE-JOE-NGIGI Try to clean all files and build it from scratch. Worked for me.
