MC 1.12-pre2 deprecated SQL class, SQL fails

[Romaq]

Spigot/ MC 1.12 pre-release 2

"File" method appears to work fine, though I didn't start to load it yet.

Initially, I used "url" instead of "uri" for the config, and it correctly overwrote the values in the config file, "Do it THIS way, try again!" I changed the label to uri, made sure spaces-not-tabs as displayed by Notepad++

  backend: sql
<config stuff>
  backends:
    sql:
      user: <correct_username>
      password: <password>
      type: sql
      uri: mysql://<someip>/<database>

Going back to file method for the time being.

EDITED to complete the stack trace.

The warning message is unrelated to your error. Unfortunately, you cut out the majority of the actual stacktrace for the real error so we can't help you much with that.

[Romaq]

I'll edit the message to put the stack trace in.

If there is anything else I can do to help, let me know. We are a very small server and we understand "bleeding edge", so it is no problem for me to look up specifics or try things so we have PEX ready for 1.12 roll-out, esp. for those of us who want SQL support. :)

Unfortunately PermissionsEx is currently unmaintained and no further updates are planned. Because of this, all pull requests are being closed. If you are looking for an actively maintained permissions plugin, take a look at LuckPerms. It is compatible with major server platforms and can import data from PEX.
