Frequent errors whilst loading mine (or others) plugins

So i'm gonna quickly cut to the chase.
Im a new nooby develepor and im trying to make a simple plugin where you do /hub instead of /spawn

However, i get this error:

Please help as i have no clue whats going on!

 

castletaker11 Please show us your plugin.yml, because ClassNotFoundException sometimes means that your main class declaration in the plugin.yml is wrong. Also, make sure to compile the plugin with JRE6 and not with 7, that was the cause for the UnsupportedClassVersionError for a very long time and I think that's still it

 

change in your plugin.yml:

Code:

me.BenLumsden.tutorial.Main

Then u should be fine

 

sd5 HGPDev thanks! HGPDev is that wat I change it to?
If so I will try tommorow

 

castletaker11 Yes change it to the line i said. in your plugin.yml and you should be fine

castletaker11 if you only have jre7 on your computer then you are already compiling with jre7.
If you wan't to be sure then (assuming you use Eclipse) open your project, click Project > Properties > Java Build Path (on the left side of the panel) > Libraries (the tab). If there is an entry saying 'JRE System Library [JavaSE-1.7]' then it is correct.
