Intellisense not working when creating a submodule in a Gradle project unless reload vscode window

Environment

• Operating System: Arch linux (Remote Development Host)
• JDK version: Gradle: languageVersion.set(JavaLanguageVersion.of(8)) / System: 17 (installed by sdkman install java)
• Visual Studio Code version: 1.80.2
• Java extension version: v1.21.0

Steps To Reproduce

1. create a new Gradle application project using gradle init and using Kotlin DSL
2. making a new submodule

mkdir -p mylib/src/main/java/com/example/demo
touch mylib/src/main/java/com/example/demo/MyClass.java
# ... and writing some java code for this file

the content of mylib/src/main/java/com/example/demo/build.gradle.kts

plugins {
    id("java")
}


java {
    toolchain {
        languageVersion.set(JavaLanguageVersion.of(8))
    }
}

3. add this submodule to settings.gradle.kts

- include("app")
+ include("app", "mylib")

4. now try to use this lib in app module, it works well, all prompt are working well
5. open mylib/src/main/java/com/example/demo/MyClass.java, try put some code to this file, but there are no any prompt (e.g. press sout should show a dropdown contains a snippet item for System.out.println, but there is no any on there)
6. Ctrl+Shift+P and then running Developer: Reload Window, now all working well

Current Result

Additional Informations

I'm also using vscjava.vscode-gradle.

Please let me know if you can't reproduce this problem or need a log file, I'm busy for working and I will send some detail you need after work.

レポートに記載されている Gradle プロジェクト、settings.gradle.kts、build.gradle.kts、my​lib/src/main/java/com/example/demo/MyClass.java で問題を再現します。まず Developer: Reload Window の前後で IntelliSense を比較し、次に Java 拡張機能が新しく追加されたサブモジュールをどのように扱うかを調べます。MyClass.java でウィンドウを再読み込みせずにプロンプトが機能すれば完了です。
