Author tag checkstyle warning when using Intellij Inspect Code

Question

When I use IntelliJ's Inspect Code, the IDE shows the following warning message:

Name      
    Test.java
Location
    package test.exercisefile Test.java
Problem synopsis
    Checkstyle: @author=John.Doe (at line 32)

My actual source comment is:

/**
 * @author John.Doe
 **/
public class Test {...

I have no idea what @author=John.Doe means.
I appreciate any advice about how to fix this warning. Thanks!
