jMonkey Engine unable to find any loaders

Alweth · September 29, 2016, 2:50am

–UPDATE–
I tried using Gradle with Eclipse and have the same problem: jMonkey cannot find any loaders. See the errors and warnings I get below when I try to play an ogg file. Any help figuring out what the resource loaders are, where to find them and where they should be so that JME can find them would be greatly appreciated.

Hi, I'm using jMonkeyEngine via Maven in Eclipse. When I run a sample project, I get the following warnings and errors. The example itself seems to run fine, but I am really concerned that it's unable to find any loaders. This has stopped me from being able to run the audio examples, since jMonkey cannot find the ogg loader. Can someone give me some clues on where the loaders should be located and what they should be called? Even better, anyone experienced this and know how to make Maven bring in the loaders to the right location?

Further UPDATE:

I even tried downloading this example JME Gradle project and building it. It builds fine, but quits with an error saying there’s no registered ogg loader if I try to load an ogg:

Darkchaos · September 29, 2016, 8:57am

Ogg requires some additional libraries not part of the simple project.
You need jme3-ogg and some ogg.jar or something, I believe.
There should be some information on the wiki at the sound tutorials since I don’t really remember

yan · September 29, 2016, 9:44am

to use .ogg you need jme3-jogg*.jar, it has OGGLoader.
to use .fbx or .orge.xml model you need jme3-plugins*.jar
to use .blend you need jme3-blender*.jar

And you can find all of the maven-style artifact IDs here:

Thanks guys. That was the issue. You would think the importance of the jogg jar would be mentioned in the tutorials covering playing audio.
