Subject Re: JCasGen: Import typesystem from Maven dependency jar
Date Thu, 04 Feb 2016 22:26:54 GMT
Hi,

use an import-by-name that looks up the resource in the classpath, e.g.

  <imports>
    <import name="desc.type.POS"/>
    <import name="desc.type.Morpheme"/>
  </imports>

Looks for the "desc/type/POS.xml" and "desc/type/Morpheme.xml" in the
classpath (i.e. within your Maven dependencies).

See also https://uima.apache.org/d/uimaj-current/references.html#ugr.ref.xml.component_descriptor.imports

Cheers,

-- Richard
