Note the trait test extends SbtTests without any accompanying object. Also, common.test module is missing because there's no common/src/test folder

Note the trait test extends SbtTests without any accompanying object.

This is fixed in #6083.

Also, common.test module is missing because there's no common/src/test folder

This can be fixed with another normalization step in SbtBuildGenMain. I will add this to my TODO list.
