No tests are executed while using junit Categories - maven

Question

I am trying to run tests based on categories but doesn't seem to work. I have spring boot application
Pom.xml is
...
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.17</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</project>
And I have defined categories as well
package com.in28minutes.springboot.controller;
public interface FastTests {
}
and junit is just to test
package com.in28minutes.springboot.controller;
import org.junit.Test;
import org.junit.experimental.categories.Category;
public class B {
#Category({ FastTests.class })
#Test
public void c() {
System.out.println("Hello \n\n\n\n\n");
}
}
but when I try to run maven command
mvn test -Dgroups="com.in28minutes.springboot.controller.FastTests"
no tests are executed. I assume it should execute test from class B.
