Plugin error when headerFile nested in folder

[xqzlgy2]

If a Java project is nested inside the root folder like this:

projectRoot
│
└───JavaProject
     │   check_style.xml
     │   microsoft.header
     │   pom.xml
     └───com.a.b
         │   A.java
         │   B.java
         │   ...

And we add headerFile check in check_style.xml like this:

<module name="RegexpHeader">
    <property name="headerFile" value="microsoft.header"/>
</module>

When we set configuration file, we will get error:

Because the plugin will search for headerFile at project root, but it could not find.
Actually, the searching scope should be the path where the configuration file located, not project root.
