NoSuchMethodError while using MockHttpServletRequest - JUnit

Question

I am getting the following error when I am trying to instantiate a MockHttpServletRequest object like this: MockHttpServletRequest request = new MockHttpServletRequest();

java.lang.NoSuchMethodError: org.springframework.core.CollectionFactory.createLinkedMapIfPossible(I)Ljava/util/Map;at org.springframework.mock.web.MockHttpServletRequest.(MockHttpServletRequest.java:107) at org.springframework.mock.web.MockHttpServletRequest.(MockHttpServletRequest.java:187)

I am using Intellij IDEA; thanks in advance.

You are mixing Spring 2.0.8 and 4.2.6 jars. Never mix versions of a framework. Replace spring-mock with spring-test and use the same version as your main spring version. — M. Deinum

M. Deinum response worked for me, replace spring-mock with spring-test, additionally take a look at the .iml file and make sure the spring-mock is gone, otherwise remove it manually and re-attempt to execute the test.
