Inaccurate Scalaz-deriving Errors #1503

Open j-potts opened 3 years ago

j-potts commented 3 years ago

Hey guys,

Looks like there may be some compatibility issues with the latest scalaz-deriving and bloop. Under my multi-project mono-repo I'm using the following libs:

The issue I'm facing is that using those libs together will cause persistent errors to show up, despite not showing up when compiling within SBT. Here a code snippet as an example...

import pureconfig.ConfigReader
import scalaz.annotation.deriving

@deriving(ConfigReader)
final case class Foo(
    name: String,
    phone: String)

This will result in...

could not find implicit value for parameter F: scalaz.DerivingProducts[pureconfig.ConfigReader]

This issue seems to prevent Metals and Bloop from properly compiling dependent files, and breaks IDE functionality downstream.

Thanks for the help!

Thanks for reporting! Were you able to run with SBT BSP as suggested on Discord? I am not too familiar with pureconfig or scalaz-deriving. Might this be indeed an issue that macro annotation reads configuration from the classpath at compile-time?

I found the underlying issue to be a bug around sbt bloopInstall.

That specific scalaz-deriving functionality depends on resource files and they aren't being shared properly between projects.

Do you have maybe some sample project I can take a look at ?
