Need help with error Unsupported major.minor version 51.0

So I searched this error and other people had the problem but I did not find any solutions.
What someone said was that my methods and such are out of date which is entirely possible because I am just trying to get an old plugin to work but tailor it to my needs.

The error: http://pastebin.com/F1LYiJeD

my main method: http://pastebin.com/wPi0Y7UM

enchant class: http://pastebin.com/bNxdCLFr

inv helper: http://pastebin.com/rWqr9xT4

util class: http://pastebin.com/cJFKvGYn

I am not new to java but I am new to plugins so be gentle when you yell at me for being stupid. Thanks

Can you post your plugin.yml too?

 

yes

What version of Java are you compiling with?

 

I am compiling with 7 but I heard I have to compile with 6 which I don't know how...

EDIT: I'm using eclipse

Click on the preferences button on the top toolbar and navigate here:

 

Right click the project, Build Path - > Configure Build Path, press the Libraries tab, click on JRE System Library [JavaSE-1.7] then press Edit... (on the right), then for Execution Environment select JavaSE-1.6

 

It means you are ompiligng for java 7 but are using it for java 6.

 

Yes that worked but I get a new error that looks like it can't find the main class I don't know why...

Make sure that your files are all in their correct places and that you've exported them correctly. Try reopening the compiler and compiling the JAR again.

 

I tried that and it doesn't seem to do anything :/

Can you zip up your source folder and post it here?

 

Change
main: me.aPanda.PandaEnchant.Panda
to
main: me.aPanda.PandaTheEnchanter.Panda
in the plugin.yml

 

XD thanks

Now I'm getting a null pointer exception about an not handled event...

the code from above is the same minus the yml that I fixed thanks to V10lator <3

perms is null cause you never called setupPermissions()

 

Ohhhhh ok let me try and figure it out

Okay I got the permissions to work but it seems like the ea command is giving me problems and it has more errors associated with it but I don't know how to fix them :/

Now that you changed codes I don't know which line number is what anymore, so I can't help. But have a look at this really useful post: http://forums.bukkit.org/threads/ho...ubleshoot-your-own-plugins-by-yourself.32457/

 

I tracked down the problem areas yet i see nothing wrong (granted I am a newbie at this) it is a null pointer exception but I don't understand why...


main: http://pastebin.com/9UamAszS

enchant: http://pastebin.com/LVck51TE

InvHelper: http://pastebin.com/tVCaG8t5

Util: http://pastebin.com/pciZ3Vj9

yml is the same -

 

You read the link (just the first post, it's really helpfull)? Cause that would say line 23 in Util.java causes the error, which is impossible as this is an empty line. So the error is not from the code you gave me.

Anyway, I think I know the error: Add
Util.Initialize(this);
to onEnable, cause you're never calling that, hence server is null.

 

Ya I did read it and it was super helpful - I will try the initialize thing - thanks for the help

welp it stopped the error but now when I run the command literally nothing happens... and by nothing I mean nothing - no item no error no mesage nada. Not sure what else to do XD.

What should happen instead? You command code doesn't give any feedback to the executor...
