How to parse and transform all source code files from an sbt project with scalameta?

Question

I would like to use scalameta to parse ALL source code files from an SBT based Scala project and transform them. As the documentation states (https://scalameta.org/docs/trees/guide.html#from-programs-with-multiple-top-level-statements) I can parse SBT files with scalameta but how do I get the corresponding source code files of the project? Do I have to filter for all .scala files in the src/main/scala folder manually?

Answer 1

As written in documentation about SemanticDB they added a function to work with all .semanticdb files to internal package. I guess you can do similar thing with .scala or .sbt files. Well, basically, yes, it's on your own.
