How to configure launch settings for a Quarkus application using Gradle in Visual Studio Code?

I'm developing a Quarkus application that uses Gradle as the build tool. The application doesn't have a `main` class.

I'm trying to configure a launch setup in VS Code, but looks like something is not quite working as it should.

I created a `launch.json` file in the `.vscode` directory with the following content:

```javascript
{
  "configurations": [
    {
      "hostName": "localhost",
      "name": "Debug",
      "port": 5005,
      "preLaunchTask": "gradle:quarkusDev",
      "projectName": "${workspaceFolderBasename}",
      "request": "attach",
      "type": "java"
    }
  ],
  "version": "0.2.0"
}
```

I've also need to create a task that starts the application and attaches the debugger to the running process...but that's what I'm not entirely sure how to structure:

```javascript
{
  "tasks": [
    {
      "args": "",
      "buildFile": "${workspaceFolder}/build.gradle.kts",
      "description": "Launch Quarkus Application in Development Mode",
      "group": "quarkus",
      "id": "${workspaceFolderBasename}",
      "javaDebug": false,
      "label": "gradle:quarkusDev",
      "problemMatcher": ["$gradle"],
      "project": "${workspaceFolderBasename}",
      "projectFolder": "${workspaceFolder}",
      "rootProject": "${workspaceFolder}",
      "script": "quarkusDev",
      "type": "gradle",
      "workspaceFolder": "${workspaceFolder}"
    }
  ],
  "version": "2.0.0"
}
```

With that configuration, VS Code always display a dialog with some options because the debugger cannot be attached automatically — and I need to press the `Debug Anyway` option to continue.

Any guidance on how to properly configure the task would be greatly appreciated!
