Java wrapper now build with maven

Created by: mira13

Use case

To use new versions of libraries with known licenses and modern build system, java wrapper moved to maven.

Description

1. Maven pom.xml created
2. Folder structure changed, according with maven requirements
3. Local versions of libs removed

Possible Drawbacks

Class usage that is not supported any more - commented out (SimpleLogger doesn't support debug levels, should be replaced with neighbour class)

Testing

not applicable, travis file needs fix tho, as we don't use ant any more

If so, do the tests pass/fail?

no

Have you run the entire test suite and no regression was detected?

yes
