build.xml copy+paste detector won't pick up duplicated codes

Question

Duplicated code below present in two different controller files but the copy paste detector in build.xml won't pick it up when running the phing. The report file it generates has just empty block as shown below. Can someone tell me what I'm missing?

Thanks in advance

Answer 1

The duplicated code is not detected because the number of tokens is not enough is your code snippet, the following will be detected:

public function indexAction()
{
    $form = $this->getForm('kikoo');

    if (is_null($form)) {
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
        echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty'; echo 'form empty';
    } else {
        echo 'not empty';
    }
}

You can change the min-tokens parameter which is 70 by default:

phpcpd src/ --progress --min-lines=5 --min-tokens=70
