Apicurio-studio: Kesalahan saat memulai saat `$ mvn quarkus:dev`

Hai,

Saya mencoba mengembangkan api dengan fitur reload panas quarkus.
Tetapi ketika saya menjalankan mvn quarkus:dev sepertinya tidak berhasil.

Berikut adalah log di sekitar stacktrace:

$ cd platforms/quarkus/api
$ mvn quarkus:dev

Saya juga mendapatkan kesalahan ketika saya mengakses melalui browser:

Apakah saya memerlukan konfigurasi tambahan atau sesuatu ketika saya menjalankan api dengan quarkus?
