Which Java version have you installed?

Short googling of the “class file major version 57” message shown several links mentioning that Gradle doesn’t support Java 13.

CUBA supports Java versions from 8 to 11, so you will not be able to launch your application with Java 12+ anyway :

Thank you, installed Java 11 and it worked.
