Can't import org.hamcrest.Matchers in test files

Question

I'm trying to use hamcrest to create some tests, but I can't seem to get maven to include whatever is needed for org.hamcrest.Matchers.* to be resolved. I've seen a number of questions, such as this one, that imply there is some sort of dependency issue with importing hamcrest, junit, and mockito, but I've fooled around with my pom.xml file and no matter what I try I can't get it to work.

Here's the dependency section of my pom.xml. What do I need to do to get hamcrest to resolve properly?

Please try to replace the mockito-all dependency with mockito-core. Mockito-all includes an old version of hamcrest, which is known to cause issues. See e.g. mockito/issues/324
