Add more fine grained check for scalacOptionsToRelax

[ckipp01]

Creating this to start a conversation about it and to see if this would be alright as a follow-up to some of the work done in #196. If I understood the conversation right you want to avoid situations where this is set to error out causing issues. However, currently it strips out any usage of -Wconf. The situation that I'm in is that we want to avoid warnings from generated sources since we generate a ton of files with scalaxb that contains a whole bunch of compiler warnings. To silence these we use -Wconf:src=src_managed/.*:silent. This works great during normal compilation, but then when we run scalafix check in our CI our logs end up being full or warnings causing a scare. Would it be possible to make this more fine-grained like this to specifically target :e or :error?

Makes sense 👍

Could you reproduce your scenario by adding a (mandatory) silencing wconf in

sbt-scalafix/src/sbt-test/sbt-scalafix/relax-scalacOptions/build.sbt

Line 14 in f6fffde

"-Wconf:cat=deprecation:e",

? Thanks!

It looks like the CI failure is unrelated by the way, see #261 (comment).

I think what I have should work now.

Thanks! You can use a snapshot once master is built: https://oss.sonatype.org/content/repositories/snapshots/ch/epfl/scala/sbt-scalafix_2.12_1.0/
