I've recently changed to the new Minecraft launcher, and I have noticed a change in the
.minecraft folder layout. I can no longer install mods just by copying it over into the
versions/1.6.1 jar file, as this file refreshes every time it is launched.
For those who don't know what I am talking about, here is the new layout:
I am specifically trying to install Optifine, which does work with 1.6.1. Where do I drag in the mod files now? I can't seem to find a jar file that is suited to it, except in the version folder, but as I stated above, this refreshes every time.
After copying a recent version and renaming it in the version folder, I get this error in the development console:
Unexpected exception refreshing version list java.lang.IllegalArgumentException: Version '1.6.1' is already tracked at net.minecraft.launcher.updater.VersionList.addVersion(VersionList.java:91) at net.minecraft.launcher.updater.LocalVersionList.refreshVersions(LocalVersionList.java:44) at net.minecraft.launcher.updater.VersionManager.refreshVersions(VersionManager.java:47) at net.minecraft.launcher.Launcher$2.run(Launcher.java:164) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
