Adding Parsus as a dependency sometimes causes error: "Cannot access 'Language': it is internal in 'org.intellij.lang.annotations'"

[aSemy]

Unfortunately the @Language injection workaround doesn't play well in regular projects. The org.intellij.lang.annotations.Language defined by Parsus 'overrides' the official one provided by java-annotations, and because Parsus' is marked as internal, it causes compilation errors in the project whenever Parsus is present.

The quickest way to reproduce this is in a Gradle build script, although I also encounter the same problem in src/main/kotlin in regular projects:

// build.gradle.kts
import org.intellij.lang.annotations.Language

buildscript {
  repositories {
    mavenCentral()
    gradlePluginPortal()
  }
  dependencies {
    classpath("me.alllex.parsus:parsus:0.6.1")
  }
}

@Language("text")
val foo = "..."

The result is that whenever I have Parsus as a dependency, my project cannot use @Language at all. And I can't think of a workaround.

Suggestions

I have two suggestions:

1. Change the visibility of Parsus' @Language from internal to public.
2. java-annotations has been converted to KMP in v25.0.0, although it is yet to be released. This will provide a valid multiplatform @Language. So, for now, remove Parsus' @Language, and then when java-annotations v25.0.0 is released, switch to use that.

java-annotations 25.0.0 has been released, and should have KMP support for @Language!
