So, I noticed that the snapshots for master are still broken on jitpack:
https://jitpack.io/#jMonkeyEngine/jmonkeyengine/master-SNAPSHOT
Just as a note, -SNAPSHOT without the master also does not work, but it does have a build log…
https://jitpack.io/#jMonkeyEngine/jmonkeyengine/-SNAPSHOT
Actually,
It looks like I am getting a read timeout for all jme packages on jitpack…
try
https://www.jitpack.io
That works just fine, I can go all the way to https://jitpack.io/#jMonkeyEngine/jmonkeyengine
It looks like everything is working today. Yesterday jitpack worked except for downloading jme jar files. Today it looks like it is working. It still is acting odd though. It downloads the jme 3.1.0-beta jars at the same time as the 3.4.0-snapshot jars. It still only includes the 3.4.0-snapshot jars in the build so I guess it is fine.
