maven extension support

I'm experimenting with using this polyglot maven extension to convert my projects' pom.xml files into other languages (in particular pom.yaml or pom.kts). Maven seems to work just fine with it, but java language server doesn't seem to pick up either the maven extension or the non-xml pom file.

Is there some way to configure the language server to recognize the maven extension and/or the non-xml pom file, or is there a change that needs to be made to the vscode extension itself to pick things up?

Environment

• Operating System: Mac 14.5
• JDK version: 17
• Visual Studio Code version: VSCodium 1.88.1
• Java extension version: 1.32.0

Steps To Reproduce

1. clone https://github.com/takari/polyglot-maven-examples and open that in vscode with the java language server
2. add another dependency, e.g. guava collections compile("com.google.guava:guava:31.1-jre") to kotlin/pom.kts > dependencies
3. open Main.kts, add a line for "import com.google.common.collect.Lists" and in the main function call "Lists.newArrayList(1, 2, 3)"
4. Run "mvn install" to compile the project

Please attach logs

Current Result

because of the extension registered in the project's .mvn/extensions.xml, maven handles the alternative pom file just fine; however, vscode shows red underlines on the google import with an error about an unresolved reference; implying that the language server failed to recognize the added dependency on guava.

Expected Result

the language server recognizes the maven extension and uses it to parse and process the non-xml pom file. (completion support within the pom file a bonus)

Additional Informations

takari/polyglot-maven-examples で問題を再現し、.mvn/extensions.xml、kotlin/pom.kts、Main.kts に焦点を当てます。まず、Java language server が Maven プロジェクトをインポートし、XML ではない POM ファイルをどのように処理するかを追跡します。追加した Guava 依存関係が Main.kts で解決され、代替 POM が処理されれば完了です。
