check your internet connection and try without anti-virus program since there is an error when downloading the server

not sure which forge version you are using but java 17 is not supported yet by forge

is this for the user or for developing

it does not work because you create again a client side only mod, do this on server also again this is the wrong sub forum..!

I'm not sure if understand your question correctly but Commands are server side, if you want to add client side Commands you need to create a custom logic for them

you can register them the same way you register Items, Blocks, etc.

forge use now mojang names, withConfiguration is now called configured. You can use Forge bot on discord to convert class, method and field names

do never use @OnlyIn it's only for vanilla you can use this, also side mods are not create via @OnlyIn take a look at this

i think your are using the offical mapings, since makeDirty is now called setChanged

what kind of error? from your IDE or in the log?

not possible you can't send a custom packet from the server to the client when it's a client only mod

there are new SRG names for 1.17, unfortunately there is at the moment no easy way to get them because the discord bot is broken

you find the error yourself... Keep this Forum in English please

use debugger, to look why the value is 0, but i think it's because strongBlockHealth is static. is there a reason why the field is static or do you don't know basic java?

the installer log will generate in the same folder you run the installer drag and drop it here or upload the screenshot on a website and post the link here

post the installer log & a screenshot of the server folder
