JavaScript? You mean Java. JavaScript and Java are entirely different languages.

May you post the full stacktrace from the console?

 

Here you go
CONSOLE

It appears you have compiled your code with a JDK version lower than the JRE used to run it.

You can recompile your code with a JDK version of the same, or lower, version of the JRE used to run it.

 

So i need a JDK and JRE or?

You can recompile your code with a JDK that is the same, or lower, version JDK/JRE used to run it.

You cannot run code compiled in Java 8 and have it run on a Java 7 environment, but you can recompile the code in Java 7 and will run on both, Java 7 and Java 8.

 

Ok so would i need to download java 7 instead of 8 .. How would i fix this xD thanks for your help though <3

You can compile your plugin on any version you want, though the recommended version for Bukkit plugins is Java 6 since that's what CraftBukkit is built on. The only restriction is that you MUST run the plugin on a JRE of that version or higher (i.e. if you compiled it with Java 8, you have to run it with Java 8. If it's compiled with Java 7, you can run it on either 7 or 8, and so on).

 

Forgive me for not fully being in understanding .. But to clarify
I need My [JDK] to be 7 instead 8 than correct?

If you're running the plugin on Java 7, yes.

 

Thanks for your help guys i got it
