How to avoid DD - anomaly ?

Hello!

I try to have time to use some code-inspecting program like PMD before I deliver the code.

Sometimes I get this warnings or "i":s from PMD saying:

Multiple markers at this line
- Found 'DD'-anomaly for variable 'retValue' (lines '28'-'36').
- Found 'DD'-anomaly for variable 'retValue' (lines '28'-'32').




27    public boolean accept(final File file) {
28        boolean retValue = false;
29
30        if (file.isDirectory() )
31        {
32            retValue = true;
33        }
34        else if( checkTheFile(file) )
34        {
36            retValue = true;
37        }

        return retValue;
    }

...but I'm not sure what they mean?

In the example above I have also tried like:

public boolean accept(final File file) {
    boolean retValue = false;

    if (file.isDirectory() ||(readConfigurationAssembly(file)) )
    {
        retValue = true;
    }

    return retValue;
}

But then I get:
Found 'DD'-anomaly for variable 'retValue' (lines '28'-'32').

I found this explanation but I do not sure I understand it, acctually I do not understand it at all:
DD - Anomaly: A recently defined variable is redefined. This is ominous but don't have to be a bug.
...at:
http://pmd.sourceforge.net/rules/controversial.html

Is there a better way to write this code?
Btw PMD doesn't like diffrent return points either.

Love to get some comments about how to make PMD happy.

Best regards
