PhpStorm inspection errors for thrown exception

Question

I am trying to catch a custom exception, but keep getting an Exception 'CustomException' is never thrown in the corresponding try block inspection error for the following scenario:

class CustomException extends Exception { }

class Test {

    /**
     * @throws CustomException
     */

    public function willFail()
    {
        throw new CustomException('I failed');
    }

}

$test = new Test;

try {

    $test->willFail();

} catch (CustomException $e) {

    echo $e->getMessage();

}

The above example works exactly as expected, aside from PhpStorm giving me the inspection error.

I've searched everywhere and can't find out how to fix this without disabling the inspection entirely. Any help would be greatly appreciated!

Just in case anyone else runs into this problem themselves in the future, I'm posting the solution to this problem.

This was fixed by updating "Call tree analysis depth" to "1" in Preferences > Languages & Frameworks > PHP. Click on the "Analysis" tab and update the setting there.
