typeerror - Minecraft won't run. Multiple items cannot be resolved to a type -

i finished skating around infamous "cannot load main class start" thing, , got blindsided sea of errors:

a friend suggests might have com.google, can't me.

i haven't made single alteration of code far. eclipse started not being able run , stayed way. think there's way fix require making acute changes @ sight of every single error; work wiped cleanup if i'm proved wrong.

anyone have clue issue is? thank trouble.

update: adding guava library relieved error involving com.google, threw in handful of others. 1 class file contains 3 of common unresolved types i've seen scattered throughout: logger/logmanagaer, propertymap, , crashreport

your general problems revolve around not having dependencies in build path. eclipse's error messages pretty clear this; e.g. if package name underlined in red , can't found, means can't found, , obvious solution add library provides it, can found.

in virtually cases here, google search missing packages , classes lead packages contain it.

for each unresolved dependency, find library, add build path, move on.

i suggest consulting documentation comes source code attempting compile, lists dependencies, saving trouble of hunting them down go.

while internet searches , hash out 1 step @ time, it's both better , faster yourself. better because if you're messing around minecraft source, having @ least basic knowledge of how tools work going you (i suggest of material @ http://docs.oracle.com/javase/tutorial/). faster because turnaround time of typing package names google search box heck of lot faster updating question here , waiting replies.
