Upgrade error - java.net.UnknownHostException: central.maven.org

[Chris Whitcomb]

I'm just a little behind in my upgrades.  I'm currently on 3.3.0 and finally had some time to upgrade.  

I'm running Linux Mint 19 Cinnamon.  I'm not sure what Debian version that is.  

I upgraded my Java version to zulu 13 thinking that was the problem.  I'm still getting the following error when trying to run jGnash 3.4.0 for the first time:

INFO: Downloading http://central.maven.org/maven2/org/openjfx/javafx-base/13.0.1/javafx-base-13.0.1-linux.jar to /home/chris/jGnash/jGnash-3.4.0/lib/javafx-base-13.0.1-linux.jar

java.net.UnknownHostException: central.maven.org

I am not behind a proxy.

Thanks,

Chris

Sorry.  I missed the post about maven moving the repos to https.  

I'd rather not manually download all the libraries.

Since 3.4.0 is non marked as a file format change, is it safe to skip and go directly to 3.5.0 from 3.3.0?

Thanks.
