Get SemanticTest running in intellij

[olafurpg]

It should be possible to replace the exposePaths hack in build.sbt with
https://github.com/sbt/sbt-buildinfo

A nice side effect of the tests cleanup in #165 is that we no longer use the hacky exposePaths trick, build info generates all the necessary file path strings. This means the scalafix-testskit tests should run cleanly in IntelliJ with full support for breakpoints and everything. NOTE however, you need to run sbt test:compile via the terminal first to trigger the BuildInfo code generation.

I tried to run SemanticTests but I get a cryptic "Error:Module 'unit' production: java.lang.NullPointerException". I have little experience compiling projects from IntelliJ. @ShaneDelmore Could you maybe checkout master and try running SemanticTests.scala from intellij?

I just successfully ran SemanticTests via intellij

I had to specify the output path in the Project Structure but otherwise I didn't need any custom setup. You still need to run sbt test:compile once to generate the BuildInfo objects.

@olafurpg I see I missed your message to test this out previously. Sorry about that but thanks for verifying it works.

No worries @ShaneDelmore ! I miss messages in my inbox all the time 😅
