why is aopalliance required?

[Pablo Fernandez]

Hi.

My code compiles cleanly just with the basic guice.jar but when I try
to run some test I get the following error:

java.lang.NoClassDefFoundError: [Lorg/aopalliance/intercept/
MethodInterceptor;

Isnt aopalliance an optional dependency that you throw in just when
you use guice AOP?

Thanks!

PD: Obviously I'm NOT using AOP, just simple DI

The AOP Alliance API is just a set of interfaces. Guice implements and references those interfaces, so they need to be in your classpath, even if you don't use that functionality.

Or, you could use the "no aop" version of Guice (available on the downloads page).
