Answer 1

Did you include the hamcrest-core-1.3.jar file in your classpath? If not included means include that jar and try once again.

Answer 2

add junit.jar to your project dependence. you may also need to add hamcrest.jar in addition.

Open File->Project Structure,Click Modules->Dependences,add junit.jar.

Answer 3

If you come across this (and a few other threads) on this error and adding the jar to dependencies doesn't work, you will need to add to the general java classpath.

I encountered this error in OSX where maven would download the dependency, but not find it when in fork mode.

Adding all the hamcrest jars to Library/Java/Extensions finally fixed the problem when nothing else would.

Answer 4

Latest version of hamcrest-all is available at: https://search.maven.org/search?q=a:hamcrest-all

Download this version (as opposed to the hamcrest-core) and that should do it.
