Solved Plugins not working.... (Help)

Hello my name is webbhead and I have been having some issues when using my plugins. When I first get finished with one I upload it to my testing server it works perfectly fine no issues what so ever... However when I upload it to the server I will actually be using it on it completely over looks it and doesn't even show an error in console. My testing server is 1.7.x / 1.8.x and the server I am using it on is also 1.7.x / 1.8.x any ideas if you want me to show you the jars in the Build of the plugin and the server jars just tell me and I will post a picture of them.

 

Does your server console show that they are being enabled?

 

On my testing server yes it shows it being enabled on the server I will actually be using it on... No it does not.

 

They are most likely not being uploaded to the actual server then, for some reason or another

 

I'm uploading it straight into the plugins server where all of the other plugins are.

 

Honestly, I think that you've posted this in the wrong section

Are you sure? Are you using a FTP client (such as FileZilla) so that you can check that the JAR files are being uploaded to the "plugins" folder?

 

I have not used an FTP Client I only used the Multicraft FTP to upload it to the server.

 

Right, so they are being put into the "plugins" folder then? Have you restarted the server when you've added these plugins? Normally when a plugin cannot be loaded, there is an error that shows in the console, try checking your logs if all else fails

 

It still didn't work when I attempted to upload from FileZilla it said Success then I restarted the server and still wasn't showing up and no logs in the console showed. Could it be something with the Bukkit/Craftbukkit jar file? My jar file is: bukkit-1.7.10-RO.1-20140817.175650-8.jar

 

@webbhead If you uploaded it correctly in the right folder but the plugin did not load, there would be an error thrown. Check the console thoroughly to see if your plugin is even being loaded.

 

I just ran it on a different server and it is still not working but this time I found an error: http://pastebin.com/ZcVgj6CX Read From the Bottom to the top of the thing multicraft prints out from the bottom. I have never seen this error before. I also get this same error on all other plugins I have made recently, but it works perfect on my LocalHost testing server.

 

@webbhead What version is your server running and what Java version did you build with?

 

My server is running a spigot/craftbukkit version (My Testing server). The server my plugins wont work on is running spigot/craftbukkit. My JRE and JDK are both 1.8.0_25

Anyone else have this issue and know how to fix it??

I found the "Caused By:" but I don't know what it means or how to fix it.. Here it is:

Code:

04.01 23:33:15 [Server] INFO Caused by: java.lang.UnsupportedClassVersionError: me/webbhead/hub/Hub : Unsupported major.minor version 52.0

This is the error:

Code:

04.01 23:33:15 [Server] INFO org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: me/webbhead/hub/Hub : Unsupported major.minor version 52.0
04.01 23:33:15 [Server] ERROR Could not load 'plugins/FortShieldHub.jar' in folder 'plugins'

Solved! I needed to downgrade from JRE/JDK 1.8.0_25 to JRE/JDK 1.7
