Can't start IDE. It's say Connection Refused

When I try to start IDE on Studio, shows:

[15:32:37.277] Ready[15:32:40.229] Creating/updating IDEA project files:ideaModule:ideaProject:ideaWorkspace:idea:app-core:ideaModule:app-core:idea:app-global:ideaModule:app-global:idea:app-gui:ideaModule:app-gui:idea:app-web:bindVaadinThemes:app-web:ideaModule:app-web:ideaBUILD SUCCESSFULTotal time: 2.23 secs[15:32:45.492] IDE integration: java.net.ConnectException: Connection refused

Studio cannot start your IDE. It can only connect to an already running IDE and make it open your project and particular file.

Please run the IDE and install CUBA plugin as described here.

Probably you use HSQL database for your application. It is served by Studio by default.

I would recommend swithing to a standalone DBMS like Postgres:

  • Set up the DBMS

  • Change database type for your project in Project properties

  • Generate DB scripts again for your new database

how can i set up the new database
