I'm writing my mod in Scala, and I suddenly started getting these errors when compiling: == Recompiling client == > Cleaning bin > Recompiling '"scalac" -encoding UTF-8 -deprecation -target:jvm-1.6 -classpath "lib:lib/*:jars/bin/minecraft.jar:j...' failed : 1 == ERRORS FOUND in SCALA CODE == src/minecraft/cpw/mods/fml/common/IFMLSidedHandler.java:29: error: value EntityRegistration is not a member of object cpw.mods.fml.common.registry.EntityRegistry import cpw.mods.fml.common.registry.EntityRegistry.EntityRegistration; ^ src/minecraft/cpw/mods/fml/common/IFMLSidedHandler.java:42: error: not found: type EntityRegistration Entity spawnEntityIntoClientWorld(EntityRegistration registration, EntitySpawnPacket packet); ^ I don't edit those classes, and I haven't restarted my computer or anything. That problem just started happening when I compiled one time, and now it won't go away. What can I do? I'm using Scala 2.10.0 (not sure if 2.10.1 is compatible).

Hmm... Nothing seems to be locking it as far as I can see. I have write permissions on it. It's never done this before. Maybe it's related to Forge downloading the jars during install, and the wrong permissions being set?

It's a completely clean jar, downloaded by Forge. Here's the relevant part of the output: == Reobfuscating server == > Cleaning reobf > Generating md5s > Packing jar > Reobfuscating jar '"java" -cp "runtime/bin/retroguard.jar:lib:lib/*:jars/minecraft_server.jar" RetroGuard -notch temp/s...' failed : 1 == ERRORS FOUND == Unrecoverable error during obfuscation, see log file for details.

I'm running Python 2.7.2, but I don't think that's important in this case.

Not the OP, but sk89q's launcher is the only one I've had problems with. I tried fixing the issue in SK's code myself, but it's completely the part I was looking at was undocumented . Edit: It's caused by the fact that Forge tries to interface with net.minecraft.Launcher, which doesn't exist in most alternative launchers.
