Guava's Maven dependencies are suddenly extensive

[shs96c]

Animal Sniffer and Error Prone would seem to be compile-time dependencies. JSR305 isn't needed at runtime either, particularly from Find Bugs. Previously, guava had no additional runtime dependencies, which is one of the things that made it attractive.

Related issues: #2824, #2721.

I personally agree that these dependencies shouldn't be needed at all for any other than compile time, but those issues seem to point out that certain people had problems with that arrangement, so the Guava team decided to accommodate them.

What a pity that maven doesn't have a mechanism for saying "this dependency is needed at compile time, but not at runtime"

it does...you can use <optional>true</optional> on the dependency.

consumers who need the dep at runtime still need to declare it.

mmm - should have read those related issues first as well. still seems incorrect to add those deps and then require ppl to explicitly exclude them but this isn't the place to continue that conversation.
