eclipse update-site: Plugin version not shown in software install dialog

Question

I have created an eclipse plugin along with an eclipse feature and I have created an update site using eclipses export mechanism.

My problem is, that when I try to install the feature from this update site I always see the version number 0.0.0, although the configured version is 1-SNAPSHOT.

I searched the xml files generated into the site but at any place in there the correct version number is written, eg.:

I suspect that I have to add something in the content.xml but I couldn't fine any clue, what to change.

What do I need to change in the sites xml files to get the plugin version shown in eclipses software installation Dialog?

thanks to @howlger and @greg-449!

The version has to match the MAJOR.MINOR.PATCH pattern an the Label, if any, has to be separated by a dot, not by a dash.

Any other pattern is shown as version 0.0.0 in the software install dialog of eclipse.
