I was naively hoping that we do not need to maintain/develop two
versions of, e.g., Ruta. In my opinion, this is really painful in SVN
compared to git or mercurial.
I assume the changes in the POM are not so problematic at all, maybe? A
user could set the Java-level to 8 and add a dependency to uimaj-core 3
and ruta-core 2.5.0 in his project. The uimaj-core dependency wins over
that one defined in ruta, and ruta-core compiled with Java 7 should also
work in Java 8.
The JCas cover classes are, however, problematic. There is also a
manual/edited one in ruta-core: RutaBasic
(As I mention in previous mails, I am thinking about making it optional
I thought we could maybe just make a synchronous 3.0.0 release of uimaj,
uimaFIT and ruta, (and uima-as, uima-ducc, ...). Is it likely that
someone requires to work with uimaj-core 3 combined with a lower version
of ruta or uimaFIT? Could there be a reason not to upgrade all
dependencies at once?
