[Fabric] Crash on 1.21.11 with v5.7, and impossible dependency requirements (MC 26.1 / Java 25) in v5.8 hotfix

[Mehd1slh]

Hi! I'm trying to run Plan on my Fabric 1.21.11 server, but I'm running into two separate issues depending on which version of the mod I use.

Issue 1: Crash with Version 5.7+build.3306

When using the 5.7 build from Modrinth, the server crashes during startup with a NoSuchMethodError related to command permissions. It looks like it's trying to call a method that was changed or removed in Minecraft 1.21.11.

Here is the relevant part of the crash report:

java.lang.NoSuchMethodError: 'boolean net.minecraft.class_2168.method_9259(int)'
    at knot//net.playeranalytics.plan.commands.FabricCommandManager.checkPermission(FabricCommandManager.java:60)
    at knot//net.playeranalytics.plan.commands.FabricCommandManager.lambda$buildCommand$3(FabricCommandManager.java:147)
    at knot//com.mojang.brigadier.tree.CommandNode.canUse(CommandNode.java:65)
    at knot//net.minecraft.class_2170.method_9239(class_2170.java:449)
    at knot//net.minecraft.class_2170.method_9241(class_2170.java:443)

Issue 2: Broken Dependencies in Version 5.8-build-3579

I saw in the console that a newer version was available on GitHub, so I downloaded PlanFabric-5.8-build-3579.jar hoping it would fix the 1.21.11 crash. However, Fabric refuses to load this version because of what appears to be a typo in the fabric.mod.json requirements.

The mod is currently requiring Minecraft 26.1 and Java 25, which don't exist yet!

Here is the log from Fabric:

[17:50:25] [main/ERROR]: Incompatible mods found!
net.fabricmc.loader.impl.FormattedException: Some of your mods are incompatible with the game or each other!
A potential solution has been determined, this may resolve your problem:
    - Replace mod 'Plan' (plan) 5.8+build.3579 with any version that is compatible with:
        - minecraft 1.21.11
        - java 21
More details:
    - Mod 'Plan' (plan) 5.8+build.3579 requires version 26.1 or later of 'Minecraft' (minecraft), but only the wrong version is present: 1.21.11!
    - Mod 'Plan' (plan) 5.8+build.3579 requires version 25 or later of 'Java HotSpot(TM) 64-Bit Server VM' (java), but only the wrong version is present: 21!

System Info:

• Server: Fabric loader 0.19.3

• Minecraft: 1.21.11

• Java: 21

Could we possibly get a hotfix for the Fabric version to resolve the 1.21.11 method error and fix the dependency requirements? Thank you for all your hard work on the mod!

fabric-permission-api is required (Cause of the first error)
