Installation errors [logs]

If you want to install ExecutableItems, you have to first check the next page

If you already did it, and still don't work, just check the logs, most of the item you can see what the error is reading at them, here, are common logs errors to know what you did wrong.

NBTAPI

To make this plugin work on certain versions explained on Version compatibility, you need NBTAPI.

[14:34:43] [Server thread/INFO]: ================ SCore ================
[14:34:44] [Server thread/INFO]: [ExecutableItems] Enabling ExecutableItems v5.9.11
[14:34:44] [Server thread/INFO]: ================ ExecutableItems ================

[14:34:44] [Server thread/ERROR]: [ExecutableItems] To make EI work in 1.8 / 1.12 / 1.13 you need to have the plugin NBTAPI ! ( https://www.spigotmc.org/resources/nbt-api.7939/ ) 
[14:34:44] [Server thread/INFO]: ================ ExecutableItems ================
[14:34:44] [Server thread/INFO]: [ExecutableItems] Disabling ExecutableItems v5.9.11

NoClassDefFoundError | ClassNotFoundException

In this case you have different versions on EI | EB | EE -> Score

  • For example have ExecutableItems version 1.0.1 and Score 1.0.0

Example (THIS CAN BE DIFFERENT FOR ALL OF YOU, THE IDEA IS TO SEE THE TYPE OF ERROR)

One of the things can be done is

  • Reinstall the files

  • Instead of uploading the jar files through the host's website, upload it through FTP such as FileZilla or WinSCP.
