Subject Re: uimafit maven plugin: type system imports?
Date Mon, 14 Oct 2013 09:55:04 GMT
It would be possible to have just one AE per Maven module so uimaFIT generates only one descriptor.

How do you imagine to handle it if a PEAR module contains more than one AE? How would the
PEAR work?

(with parameter settings, etc.).
