Hamcrest in Fedora is currently version 1.1, which was released in 2007. Hamcrest 1.2 was released in 2009, and there were release candidates for 1.3 in 2010. I don't know about the stability of 1.3, so I'm not sure whether 1.2 or 1.3 is a better choice. Please update this package.
Updating Hamcrest is a problem because some depending packages (at least JUnit at this time) fail to build. The reason is that in 1.2, Hamcrest changed signatures of some of its methods from <? extends T> to <? super T>. As the change was intentional, I am talking with JUnit upstream on how to update their package. If I don't get an answer, we will probably have to make 2 separate packages for Hamcrest - one for 1.1 and one for 1.2+.
Thanks for the update.
I am sorry to say that, but as the JUnit guys are not responsive enough to collaborate on this situation, we will be retaining the old Hamcrest in Fedora (needed for the new JUnit). If you really want version 1.2 or 1.3RC of Hamcrest in, creating a new package would be in order.
Closing this bug as WONTFIX; if you want hamcrest 1.2, please make a separate package. Thank you.
