I got error while I want to build by my self.

git clone https://github.com/frodare/FlightHud.git
cd FlightHud
sdk install java 17.0.7-oracle
sdk use java 17.0.7-oracle

# Switch to version flighthud-1.18-fabric-2
git reset --hard 55c7452
./gradlew build

# download build/libs/flighthud-1.18-fabric-2-sources-dev.jar

It will get error ClassNotFoundException: The specified mixin 'net.torocraft.flighthud.mixin.InGameHudMixin' was not found while I start Minecraft with the flighthud-1.18-fabric-2-sources-dev.jar

Is there any error on my build process? Or where I can get a build instructuion.

Oh, I have to move flighthud-1.18-fabric-2-sources-dev.jar and flighthud-1.18-fabric-2-dev.jar both
