What steps will reproduce the problem? 1. include mockito-all:1.9.5, junit:4.11, hamcrest-library:1.3.0 2. Intermittently causes "java.lang.NoSuchMethodError: org.hamcrest.Matcher.describeMismatch(java/lang/Object;Lorg/hamcrest/Description)" 3.

What is the expected output? What do you see instead? No Exception should be thrown, Mockito should NOT package Hamcrest classes in its own jar, this obsolete version can not be managed through a build tool (Maven, Gradle, etc). It is simply a bad practice!

What version of the product are you using? On what operating system? mockito-all:1.9.5, junit:4.11, hamcrest-library:1.3.0 Windows & Mac

Please provide any additional information below. As a workaround, which is an unreliable hack is to put the hamcrest-library jar at the top of the maven dependencies. Clearly, this is not the optimal solution. Mockito MUST not include other project's packages, it is unmanageable!

Any updates?

Indeed hamcrest update is becoming more urgent as many project now use an updated version.

By the way if you have a pull request on github it would be awesome.
