Description of the Problem

I downloaded MyWarp for both 1.15 and the 1.15.2 snapshot version. I tried both them separately and my command logs was showing that MyWarp was failing to load each time.

Steps to Reproduce

Download the Snapshot version for 1.15.2 and try to run on a Minecraft server.

Affected Version

• MyWarp: mywarp-bukkit-3.1.1-SNAPSHOT-all
• Minecraft and Bukkit Implementation: 1.15.2

Additional context

Does it work when you use a new database?

If so, most likely your existing database file is corrupted, see here. It is possible that problematic file was tolerated by by older versions of H2, but - after updating the bundled H2 - is no longer usable.

In this case, you can try to export the database using H2's script interface and recreate it from this export (again, using H2' script interface) as described here. If you need help, you can also send me the database file and I see what I can do.

Here is a link to download the database file.

The other thing to is that the file is warps.mv.db and not warps.h2.db

Will doing this delete the warps that players have already created? That is the only thing that I am fearful of is deleting already created warps that players have made.

I am guessing trying to convert the file is the only way to try and save the warps?

Thanks,

No, you will (most likely) not lose any data.

The idea is to load the corrupted database using an older version of H2 (which still tolerates the corruption) and export all data as .sql. Then, create a new database using the newest version of H2 and reimport all data from the .sql.

The process is outlined in H2's docs. However, if you prefer, you can send me the database (warps.h2.db from MyWarp's plugin directory) and I will do the conversion for you.

You might be able to use an older development build of MyWarp, but the problem will just reappear whenever you update MyWarp and H2.

Right, warps.h2.db are created by an even older version of H2, warps.mv.db is correct.

Here is the link to the recreated file. It loads fine in H2, so hopefully it loads in Minecraft, too.
