This happens only to a friend of mine, I wasn't able to replicate it
I created a private 1.7.10 modpack, the relative server, and redistributed it to 6 friends, at first i shipped it with forge 1388
A friend tried to download the modpack and encountered this error:
[B#301] Exception in thread "main" [02:05:44] [main/INFO] [STDERR]: [java.lang.Throwable$WrappedPrintStream:println:-1]: java.lang.NoSuchMethodError: com.google.common.io.CharSource.readLines(Lcom/google/common/io/LineProcessor;)Ljava/lang/Object;

The entire log from the Technic console can be found here: http://pastebin.com/wi6X3YWb
He can't get to the Mojang screen, the just click "Play" and after a few seconds it returns to the launcher
He tried reinstalling the launcher by deleting the .technic folder but it didn't worked
I googled a bit and found that this happens to custom launchers that tries to download the guava 17.0 lib but fails
I tried to rollback the version of forge to the first 1300 build and it worked, he was able to play the game, but now i can't update mods like Tinkers' Constructs that requires 1384+
The problem is that he is using the official launcher, the launcher downloads the libs but don't "install" them, so, there is a way to integrate the libs in the modpack itself or there is another solution?
