Subject Re: suggestion for default pipelines
Date Wed, 16 Apr 2014 08:35:51 GMT
It would be nice if uimaFIT provided a Maven plugin to automatically
generate descriptors for aggregates. Maybe if we come up with a 
convention for factories, e.g. a "class with static methods that do
not take any parameters and that return descriptors", or "methods
that bear a specific Java annotation, e.g. @AutoGenerateDescriptor)"
it should be possible to implement such a Maven plugin.

Cheers,
