Lucene conflict with MinimalWorkingExample

[alainde...@gmail.com]

I am trying to use DKPro TC into my own project. To that effect, I have cloned the MinimalWorkingExample from dkpro-tc-examples and copied it into my project under the new name MinimalWorkingExample2.

But when I run it, I get:

2019-10-03 12:08:42 ERROR [main] (DefaultLoggingService) - [MetaInfoTask-trainTest-20191003120841583] Task failed [org.dkpro.tc.core.task.MetaInfoTask-trainTest](caused by NoSuchFieldError: LUCENE_44)

See the end of the message for the complete output. 

When I look at the dependency tree of my project, I see that it has two versions of lucene-core: 1.4.4 and 7.5.0 and that it is ignoring the 1.4.4 version. 

I can't remove the 7.5.0 version because the rest of my code needs that version. 

Any suggestion on how I could deal with that?

I tried modifying dkpro-tc/pom.xml to upgrade the lucene versio to 7.5.0:

    <lucene.version>7.5.0</lucene.version> 

After a number of modification, I was able to compile it and run the tests.

All tests run except one in dkpro-tc-examples (ModelProviderConversionFeatureTest.testAnnotator) which uses a Lucene index dump that is in 6.0 format (which is not supported by 7.5.0).

I would like to contribute those changes back to the project. What is the way to proceeed with that?

Thx.
