Building android project in a docker container builds only intermediates folder

I'm building a simple project inside docker (image with android-sdk and gradle 6.5) The code, I'm pulling has no gradle wrapper. Thus I use this code:

cd "Sample Code"
gradle wrapper --gradle-version 6.7.1 --distribution-type all
gradle :sample:assemble

The output I get in build folder is only intermediates dir, no generated, no outputs apk, etc. The build.gradle of project level and on app level are present. No failures observed in logs. What am I missing? Thanks
