Can't get fabric to use the main version

[Coding-Kiwi]

Describe the problem

I did not configure the VERSION variable, so the server started with version 1.18
then I restarted the server, meanwhile 1.18.1 was released so the server automatically uses 1.18.1, sadly some fabric mods are not yet compatible. So I changed the VERSION to 1.18

The server log correctly says

[init] Resolved version given 1.18 into 1.18

but it then continues to use the subversion

[INFO] [FabricLoader/GameProvider]: Loading for game Minecraft 1.18.1
[main/INFO]: Loading for game Minecraft 1.18.1

1.18.0 does not work

I can reproduce this issue.
This is possibly related to #1191.

You can delete fabric*.jar and server.jar from your data directory as a quick fix until we've implemented a solution. This will re-download and run the correct version of 1.18.

[itzg]

Re-pull the latest image to get the fabric installer updated fix.

Meanwhile @Coding-Kiwi I'm confused about what your actual problem scenario was. You left out VERSION in the compose file, so latest resolves to 1.18.1. But then you talk about setting 1.18 but didn't provide any logs to show how that didn't work. And 1.18.0 doesn't exist. Mojang always leaves off the ".0".

The problem is that after installing 1.18.1, setting VERSION=1.18 does not start the server on version 1.18. Instead it continues to start on 1.18.1.

I've verified this, but did not test to see if #1193 fixed it (yet)

[Coding-Kiwi]

@itzg I started the server with no version specified when minecraft 1.18.1 wasn't released yet, so it resolved to 1.18. I then restarted the docker container days later, meanwhile 1.18.1 was released and no version = latest = 1.18.1 and because 1.18.1 was causing trouble, i tried to downgrade from no version = latest to 1.18 by specifying it in compose

[itzg]

So going from 1.18.1 down to 1.18 it still tries to run fabric 1.18.1? Please provide the full container logs.

[Coding-Kiwi]

@itzg

So going from 1.18.1 down to 1.18 it still tries to run fabric 1.18.1?

Yes

The logs I posted above are the full container logs, from docker-compose up to crash, with VERSION set to 1.18

Do you need something different?

[StoneLabs]

I've retested. #1193 did not fix the issue.

I believe the issue might be that in

docker-minecraft-server/scripts/start-deployFabric

Lines 25 to 27 in 79fa4b9

	export SERVER=fabric-server-${VANILLA_VERSION}-${FABRIC_INSTALLER_VERSION}.jar
	if [[ ! -e ${SERVER} ]]; then

we check to see if the fabric jar exists. However, because 1.18 was previously installed no setup is performed.
Therefore, the fabric installer is never started and thus never replaces the actual Minecraft server.jar

While the correct fabric server wrapper (1.18) is started as can be seen in the output of ps -aux, the version of the actual server jar has never been downgraded to 1.18 from 1.18.1. The sever therefore continues to run Minecraft version 1.18.1.

@StoneLabs thank you very much for testing!

As for solutions to the problem: The first I can think of is just telling the installer to place the downloaded minecraft jar at server-{VANILLE_VERSION}.jar. Then, we can simply set fabric-server-launcher.properties to contain the correct jar on every start of the server.

Example: after installing 1.18 the server jar should be named server-1.18.jar and on each start, we should write serverJar=server-1.18.jar to fabric-server-launcher.jar. That would ensure the correct jar is used every time.

However looking at the installer source ServerHandler.jar L70-L75 it does not appear that there is an argument that allows us to specify the target of -downloadMinecraft. Which is somewhat annoying. So might want to just mv server.jar server-{VANILLA_VERSION}.jar after each launch. Idk

Would like to hear some thoughts/feedback on this.

The latest image now includes the fix from #1197 . I'll get this merged to the other image variants later today.
