Google Collections sources don't compile

I just downloaded the Google Collections sources and imported them into a new Eclipse project with JDK 1.6.

They don't compile for a couple of reasons:

• javax.annotation.Nullable can not be found
• javax.annotation.ParametersAreNonnullByDefault can not be found
• Cannot reduce the visibility of the inherited method #createCollection() from AbstractMultimap
• + 11 similar ones
• Name clash: The method forcePut(K, V) of type Ab开发者_运维技巧stractBiMap has the same erasure as forcePut(Object, Object) of type BiMap but does not override it
• + 2 similar ones

What am I missing?

I also wonder if unit tests for these collections are available to the public.

Seems like you're missing JSR-305 as dependency. Try adding it to the classpath.
