ClassNotFoundException - Multi Project build

See original GitHub issue

Hi there -

Ran into an odd issue when I was leveraging this in a multi-project build with scalafmtOnCompile := true. If I ran:

sbt "project someProject" clean reload compile

I would receive an exception (noted below).

However, if I ran:

sbt clean and then sbt "project someProject" reload compile

Things worked as intended. Not sure exactly what’s going on here.

I ran into the same issue. In my case, the cause was libraryDependencies := instead of libraryDependencies ++=. Hope it may help some of you 😉
