Subject Re: uimafit maven plugin: type system imports?
Date Mon, 14 Oct 2013 09:30:22 GMT
I gave up on integrating uimaFIT-based builds with PEAR packaging, there 
are fundamental differences that I don't know how to resolve cleanly, in 

uimaFIT: 1 maven artifact = N analysis engines = N generated descriptors

PEAR packaging maven plugin: 1 mvn artifact = 1 AE = 1 descriptor = 1 
generated PEAR

I don't think it's worth it to extend the PEAR packaging maven plugin to 
generate multiple PEARs, so we'll just stick with having PEAR packaging 
as something separate.

I'm actually thinking of separating "components" packaged as PEARs (as 
described by the XML descriptors) from "analysis engines" (the actual 
code) packaged as JARs, with separate namespaces. That's pretty much the 
separation we have right now, but without the separate namespaces. In 
that case it would be clear that a component is basically a packaged 
engine (with parameter settings, etc.).

I created UIMA-3346 (https://issues.apache.org/jira/browse/UIMA-3346) as 
for other descriptor based workflows it would still be very useful to 
have automatically generated descriptors that are ready to use with type 
system imports.
