How to fix   Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Bug introduced by
It seems like withOptions() must be provided by classes using this trait. How about adding it as abstract method to this trait?

This check looks for methods that are used by a trait but not required by it.

To illustrate, let’s look at the following code example

trait Idable {
    public function equalIds(Idable $other) {
        return $this->getId() === $other->getId();
    }
}

The trait Idable provides a method equalsId that in turn relies on the method getId(). If this method does not exist on a class mixing in this trait, the method will fail.

Adding the getId() as an abstract method to the trait will make sure it is available.
