Java project in subdirectory of workspace

Hello,

I'm in the same situation as https://github.com/microsoft/vscode-java-dependency/issues/493 and would like to understand how things are supposed to be configured.

I'm having a folder structure like

my-project/ (workspace)
 L java-app/
   L pom.xml
 L frontend/
 L some-other-sub-project/
 L my-project.code-workspace

My workspace file looks like

{
	"folders": [
		{
			"path": "."
		}
	],
	"launch": {
		"configurations": [
			{
				"type": "java",
				"name": "Launch My project java app",
				"request": "launch",
				"mainClass": "com.example.javaApp.MainClass"
				"envFile": "${workspaceFolder}/.env",
				"projectName": "java-app",
				"args": "--spring.profiles.active=development"
			}
		],
		"compounds": []
	}
}

But

• the "Java Projects" section in the explorer is empty
• when running my launch config I'm getting

  ConfigError: The project 'newstimeline-server' is not a valid java project.

When I change my workspace to

	"folders": [
		{
			"path": "."
		},
                {
			"path": "java-app"
		},
	],

then my project is shown in the "Java Projects" section and I can get the launch config to somehow work.
But that seems more like a workaround.

How would the java extension pack expect me to configure this situation?

Riproduci la disposizione del workspace segnalata con java-app/pom.xml e la configurazione di avvio .code-workspace fornita. Inizia esaminando come l’estensione Java rileva i progetti nelle cartelle del workspace annidate e risolve projectName. Il lavoro è completo quando la vista Java Projects riconosce il progetto annidato senza aggiungere java-app come cartella del workspace separata e la configurazione di avvio funziona in modo coerente.
