Java Maven + Eclipse + junit: package not found

问题

I have a project on eclipse in which junit is included as dependency in pom.xml:

   <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>

The project compiles well and dependency is properly resolved. I created my test folder under /src directory and added some class. However, the namespace org.junit cannot be found on my code until I "Fix project setup" to include JUnit4 Maven Dependency.

I think this should not be necessary since I included the dependency on the pom.xml. Right?

What I am doing wrong here?
