I'm pretty new with both Scala and ENSIME. I have a project and the first setup is ok with ENSIME that seems to work fine (auto-completion working, jump to definition working, error highlighting working, etc.). Anyway I've added a dependency in build.sbt (in particular I've added circe). ENSIME in Emacs keeps complaining object circe is not a member of package io.
I initially recompile the project in a separate shell. Nothing changed. After that I tried to recompile the project from Emacs with C-c C-b c. Nothing changed again.
What am I missing?
You need to re-generate the ensime configuration if you change anything in your .sbt files. Run sbt ensimeConfig in your project folder and restart Ensime inside Emacs.
