253: `org.intellij.intelliLang` is reported as bundled module, but it's unavailable

[jansorg]

What happened?

In my plugin I have this:

dependencies {
  intellijPlatform {
    bundledPlugin("org.intellij.intelliLang")
  }
}

With 2025.3 EAP1, 2.9.0 warns about this:

Could not determine the dependencies of task ':plugin:compileJava'.
> Could not resolve all dependencies for configuration ':plugin:compileClasspath'.
   > The 'org.intellij.intelliLang' entry refers to a bundled plugin, but it is actually a bundled module. Use bundledModule("org.intellij.intelliLang") instead of bundledPlugin("org.intellij.intelliLang").

But after changing to bundledModule, it also rejects it:

dependencies {
  intellijPlatform {
    bundledModule("org.intellij.intelliLang")
  }
}

prints this:

* What went wrong:
Could not determine the dependencies of task ':plugin:compileJava'.
> Could not resolve all dependencies for configuration ':plugin:compileClasspath'.
   > Specified bundledModule 'org.intellij.intelliLang' doesn't exist.

Steps to reproduce

Setup as above

Gradle IntelliJ Plugin version

2.9.0

Gradle version

8.14.2

Operating System

Using bundledModule("intellij.platform.langInjection") appears to work, though.
Either the search for modules by name is incorrect or the message about the bundled module to use is incorrect.

Also seeing this -- 253.x backwards compatibility seems a bit complicated --

1. Renaming if IC/IU.. Suggestion: rename IU (the code for the new unified IJ IDE) to IJ #2028
2. This issue.

Just stumbled across this too, would be good if the error message could be improved :)
