Support <annotationProcessors> configuration element

[sewe]

There exist annotation processors which are not declared in META-INF/services/javax.annotation.processing.Processor. These processors need to be explicitly selected using the maven-compiler-plugin’s <annotationProcessors> configuration element (the equivalent of javac’s -processor <class>).

AFAICT, this option is not supported by m2e-apt yet, making it impossible to configure annotation processing for such processors.

FWIW, I am aware that the JDT UI doesn’t seem to support explicit processor selection akin to -processor at the moment. I’ve already filed a bug report for that.

Yeah sorry, we can't work around JDT APT for that. Maybe @brychcy will be interested in fixing it upstream ;-)
