`NoSuchElementException`: typer when a plugin runs after typer

See original GitHub issue

Compiler version

3.0.2, 3.1.0-RC2, 3.1.0-RC3.

Confirmed to work on 3.0.0 and 3.0.1.

Minimized code

// This plugin adds a phase after the "typer" phase.
// Note that in 3.0.x it uses FrontEnd.name which is still "typer" underneath.
compilerPlugin("org.polyvariant" % "better-tostring" % "0.3.9" cross CrossVersion.full)

package demo

case class Foo(s: String)

Output

java.util.NoSuchElementException: key not found: typer while compiling /Users/jkozlowski/dev/app/target/scala-3.1.0-RC3/classes/demo/Foo.tasty

Expectation

Docs compile 😃

Extra info

Adding the plugin clearly surfaces the issue - without it, it’s fine.

Hopefully there’s just something wrong with the plugin, in which case I would greatly appreciate help on fixing it - sources are in https://github.com/polyvariant/better-tostring/blob/v0.3.8/plugin/src/main/scala-3/BetterToStringPlugin.scala (the behavior can be reproduced on 0.3.8 on all versions except 3.1.0-RC3)

Looks like your plugin is enabled when running scaladoc (likely via sbt doc) which is based on the compiler but doesn’t run the typer phase, is this happening with addCompilerPlugin or are you enabling the plugin by hand? If the latter, sounds like you need to better scope your settings to the compile task.

I have tried to run doc command on your project after releasing my branch with the fix and it seems it is working well. Could you @kubukoz confirm it too?
