How do I build gdx-gltf-demo.jar?

[mgsx-dev]

you need to run gradlew dist, you'll find the jar file in demo/desktop/build/libs folder.
due to old gradle version, i'm not sure you can use latest java versions, should be fine with java 8 though.
Let me know if it works for you, i'll add it to the readme.
Thank you for your feedback.

I can reproduce the issue (sorry about that), it's a timing issue with remote loading models from khronos github (default mode) so it'd better to use local mode, see how to run it locally.

Since the demo was mainly here for testing purpose, i didn't hardly tested all the cases recently. However, it becomes useful and considered more as a "GLTF model viewer" so i should probably totally reconsider this loading process.

I should have included the output (including stack trace) before. It shows that the NPE is encountered when parsing morphing.gltf

edit: sorry I read the "about JAR name" message and somehow missed the previous one about running locally

Thanks very much for your support. I've built the demo and downloaded the glTF samples, and can now easily run on desktop. 👌

Okay I got it running with

./gradlew clean :demo:desktop:dist
# or just `gradlew dist` to build the whole thing, as mentioned, but then I had to set up the Android sdk
java -jar demo/desktop/build/libs/desktop-0.0.1-SNAPSHOT.jar

But I got an NPE from GLTFDemo. I put in an assertion and found that rootModel is null on line 596, but the name of the jar is different than expected. Am I doing it right?

about JAR name, it doesn't matter, i rename it when attaching to a release to avoid changes in documentation.

[mgsx-dev]

i'm keeping it open because of the bug in the demo and lack of documentation, just as a reminder for me :-)
