App Crashes when launched from .jar about vis-ui

[kotcrab]

What build system? Gradle or Maven?

This is the error I get when trying to launch my game from a runnable .jar
file:

That line is when I call: VisUI.load();
I have had this happen with my own LibGdx addon
https://github.com/StrongJoshua/libgdx-inGameConsole.

The only way I was able to prevent my plugin from erroring was to load the
skin that it uses from my game itself, rather than the dependency's
project. Maybe you have more insight into how to fix this.

LibGdx projects use Gradle, so that's what I'm using.

[kotcrab]

Can't reproduce on fresh project from GDX setup app, also tested with Maven and everything works fine. Probably there is something wrong with your build scripts.

[StrongJoshua]

Alright I'll have a look at them after school. Can you post your working build script?

I checked my build.gradle over and even tried using a clean project, but both showed the error. Maybe the problem is how I am packaging my game. How are you doing it? I just use the Eclipse export function (which worked before I included VisUI).

[kotcrab]

You can't use Eclipse export when using Gradle. See https://github.com/libgdx/libgdx/wiki/Gradle-on-the-Commandline#packaging-for-the-desktop

[StrongJoshua]

This is what I had been following: https://github.com/libgdx/libgdx/wiki/Deploying-your-application#deploy-to-windowslinuxmac-os-x Why is this incorrect?

[kotcrab]

It's form old build system, before Gradle was used. That page you linked says: "Note: if using gradle you may prefer following the guidelines provided on this page." It says "prefer" but the new Eclipse project setup page only links to Gradle packaging: https://github.com/libgdx/libgdx/wiki/Gradle-and-Eclipse#packaging-your-project . Looks like Eclipse can't package resources from libs jars for Gradle based projects.

[StrongJoshua]

To do this I would need gradle installed and have it in my PATH, correct? Or is there some built-in gradle command line in Eclipse?

[kotcrab]

No, all you need is already in your project directory. You can just run gradlew desktop:dist command from cmd/terminal.

[StrongJoshua]

Just as an aside, do you know what the highest java source compatibility I can use is? Because I programmed a lot of things on 1.8, but I think I remember something about android only being able to use 1.6 Is this still the case?

[kotcrab]

Desktop only: 1.8
With android: the safe one is 1.6, you can use 1.7 but not all features are supported.
GWT and iOS: I don't know, 1.6 will definitely work

Please use #libgdx irc for such questions.

[StrongJoshua]

Alright, well thanks anyways :)
