Taking into account @aaime's comment

- no system.out.println calls (was only meant to debug, no intention to
  let it in the code)
- Restoring correct lib versions in the pom files
- Removing local repository

Still TODO: I'm not sure on how to deal with GDAL jar path (see
modules/plugins/ogr/ogr-jni/pom.xml:110). We might assume that the GDAL
native lib should be reachable by the JVM, then removing the extra jvm
parameter ? I needed it for testing purposes locally since I got a
specific GDAL/OGR setup.
