{quote}
(Translation: Annotation processor "" not found)
The reason I keep the {{annotationProcessors}} block is that the
{{OtherAnnotationProcessor}} was already commented out and I wanted to
additionally disable the {{MyAnnotationProcessor}}. To put the whole
{{annotationProcessors}} in a comment I would have to remove the comment
characters from the {{OtherAnnotationProcessor}} (and possibly many more).
Undoing that would also be more cumbersome than modifying a single line.
