Examples don't handle additional pmemkv-java's dependencies

[lukaszstolarczuk]

Please provide a reproduction of the bug:

If we add additional dependencies to pmemkv-java (it doesn't matter if for pmemkv-root pom file or for pmemkv-binding module), it's not downloaded when executing pmemkv-java's examples.

Expected behavior:

Examples' applications should handle our (pmemkv-java's) dependencies without extra settings in examples' pom files.
Perhaps our examples are built poorly, but maybe we're missing some setting for "exporting" dependencies with our package.

Examples fail when trying to use any method from e.g. Builder, which uses extra dependency (e.g. json for parsing objects, for fromJson method). It happened even without using fromJson method in the example.
