@youngcle Have you tried the latest commit in the develop branch? We just finished a round of testing under Ubuntu 20.04.

@Beak-man Can you please explain how to use "the latest commit in the develop branch? " I dont see a generated jar per the Travis build nor a gradle build process

First of all,thanks for the reply.
I've cloned the develop branch of the worldwindjava.

I found that the offical team changed the JDK version to 10 or above,

if it compiled with JDK 8，some code would goes wrong.

anyway, we can get it work in ubuntu 20.04 again.

I'm very glad that the offical team is still working on this great project.

Bravo!
