I'm using ubuntu 18.04 with java
>> java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.18.04)
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.18.04, mixed mode, sharing)
installed by sudo apt install default-jre (but I don't think that it is the problem)
and I have installed schemagen using apt as suggested here.
The version of schemagen is 2.3.0.1.
I have launched schemagen Moon.java but I have this error:
