@yegor256 review it please, it is a rather short pull request, no need to do a full code review

Hello
what do you think if I modify the jcabi parent to include the maven-bundle-plugin, so that we just have to change the packaging of any jcabi project to turn it into an OSGI bundle?
It will be less redundant than copying the maven-bundle-plugin configuration to each project...

@gdelafosse yes, it's a good idea. Actually, the best approach would be to declare this plugin in <pluginManagement> in jcabi/jcabi-parent and then use it in jcabi/jcabi. Then, in each project just change jar packaging to bundle. Make sense?

[gdelafosse]

I modified jcabi/jcabi to add the maven-bundle-plugin. See jcabi/jcabi#308.
As mentionned in the comments of this pull request, I wasn't able to use this parent pom into jcabi projects because of some dependencies that have been updated.
Particularly, jcabi-log versus Mockito.
