Error while running spring boot tests, SpringRunner.class Not found

Question

When I try to invoke JUnit test cases from my Spring Boot Application, I am getting following error:

I am using this annotation in my Test class.

@RunWith(SpringRunner.class)

After I add JUnit library from project dependencies, it gives me following error:

Here is my gradle dependencies:

Also, I have the affected class in the class path:

My spring boot version is 2.0.4. Editor is SpringToolSuite. Could someone please help me resolve this?

I tried running Junit by creating another sample project with Gradle and it just works fine and got surprised to see that below are the two dependencies creating issues mentioned in my post. It just works fine if I remove those dependencies. Not sure what's happening here:

compile('org.springframework.boot:spring-boot-starter-data-jpa') compile('com.fasterxml.jackson.core:2.9.6')
