Lemur file being run during .jar execution

I exported my project as a .jar file, and am trying to run it by double-click.

When I do, I get this error.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

The groovy file is being run? I have no idea why this is happening. I need to be able to run it from outside the sdk.
The line that is not working:

BaseStyles.loadGlassStyle();

I am using lemur jar file as the library, not gradle btw.

Can somebody help resolve this problem?

2

Have you succeeded to run it from the ide ? Or the javac command ?

3

Yes-- the IDE (jMonkey) Works, not javac however

4

It seems groovy.jar is not exported during the jar build…please check it inside your jar file

5

Except the exception is thrown by groovy. So that would be some trick.

OP:
What version of Java are you using to run it? Is it the same one the SDK uses?

6

@pspeed Yeah looks like even though I set to JDK 11 it defaulted to my old JDK 7… apologies

I’ll try it again

7

Have you tried :

/home/jdk11/bin/java -jar game.jar command or changing the default JAVAHOME dir ?
