I have an MBTiles map that is created by MOBAC, its tile format is JPG.

I'm trying to add this map as an MBTiles store to Geoserver, but I'm receiving the following error when I'm clicking "Save" the new store

Could not list layers for this store, an error occurred retrieving them: No enum constant org.geotools.mbtiles.MBTilesMetadata.t_format.JPG

I have another MBTiles map that its tiles are in PNG (created also by MOBAC) that works fine in Geoserver.

Does not Geoserver support JPG MBTiles?

Looking at the code, it expects that value to be "JPEG" not "JPG". However, the spec says "JPG", so it's a bug. You can report it here (it's a GeoTools issue): https://osgeo-org.atlassian.net/projects/GEOT

However, so that you get your expectations right, the mbtiles module is unsupported, so if you can, a pull request with a patch and a test would probably be the quickest way to get a fix: https://github.com/geotools/geotools/blob/master/CONTRIBUTING.md

That appears to be what the error message says, but when you check the code - it does have a constant JPEG. If we move up the call stack the issue seems to be in MBTilesFile which is getting a value of JPG from your file.

I don't know enough about the standard to know if that is an allowed value in that file. If it is then please file a GeoTools bug otherwise you'll need to raise a bug report with the developers of the tool you used to generate the file.
