As title says. First I tried to update cuba plugin to version 12, then as per the documentation I expected that after restart the installation continues, but nothing happens.
Tried to disabled the plugins restart enable again restart, same.
Tried to uninstall cuba plugin restart reinstall restart. I saw briefly a CUBA menu appearing during IDE initialisation but it disappeared quickly.
And still no further installation wizard as I understood there should have been.
There is no further installation wizard after IDEA restart. Just restart IDEA after plugin update.
You can check that new version was successfully installed by checking it in Settings > Plugins > Installed
The CUBA menu available for CUBA projects with version 6.10+ after successful Gradle sync.
