Ubooquity doesn't open on Windows 10

UnperfectOne 5 months ago updated by zrdn 5 months ago 1

I've never used Ubooquity before so I've been following the startup guide. I downloaded the .jar file from the website, put it in a folder, double-clicked it and... nothing. It generated a few folders, a JSON file and a database file, but nothing actually opened.

I checked the logs and it said the following (I tried a few more times and it just repeated the same text in my logs):

Is there anything I'm missing out or doing wrong?

probably caused by your java version. (Java version: 15.0.1)

from download page:

Ubooquity server requires Java 8 (Oracle version).
It is probably already installed on your computer. Otherwise you can download it here.
Ubooquity is not yet compatible with Java 9+.
