AnnotationException @IgnoreAnnotation

I am trying to update a plugin from 5.6 to 5.8. I got it to edit and display. but when i go to the dashboard, i get this error

Doctrine \ Common \ Annotations \ AnnotationException

[Semantical Error] The class “package” is not annotated with @Annotation. Are you sure this class can be used as annotation? If so, then you need to add @Annotation to the class doc comment of “package”. If it is indeed no annotation, then you need to add @IgnoreAnnotation(“package”) to the class doc comment of class Concrete\Package\SyntaxHighlighter\Src\GeSHi.

How can i Resolve this.

I have a GeSHi.php file with the class GeSHi in my plygin src folder

If this is an addon from the marketplace you might try reaching out to the addon developer.

This was an add one from 5.6. I was just trying to bring it into 5.8 compliance, as the current addons are not as great as this one.
