I had version 15w50a, then I attempted to update my minecraft to 15w51b. When I attempted this update, it stops at about the 90% mark. I get this message in the Game Output screen:
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release Error: Could not find or load main class net.minecraft.client.main.Main
Now when I try to go BACK to 15w50a, it still needs this download this update, and I still get this message. This affects all of my snapshot versions after 1.8.9.

Somewhere in the part of the launcher log you didn't post there is probably one or more lines that say "have local file, assuming good".
If so this assumption is wrong and these lines only show up when you have resource downloads that are timing out and not successfully completing.
Yeah, I must not have copied the whole thing by mistake, sorry about that.
Well anyway, this DID fix itself after several hours of being away from my computer. Thanks for your help!
I will make sure to get the whole launcher log copied next time I run into this.
