How to automate version number update process for my Eclipse plugin built with Maven

I working with a project similar to the project described here. So, it has a few modules in parent pom.xml:

 <modules>
    <module>../de.vogella.tycho.plugin</module>
    <module>../de.vogella.tycho.feature</module>
    <module>../de.vogella.tycho.p2updatesite</module>
 </modules>

These modules have a general version number e.g. 1.0.0-SNAPSHOT or without -SNAPSHOT. The feature.xml file needs to contain the same version number:

<feature
      id="com.my.feature"
      label="My plugin feature"
      version="1.0.0">

and:

<plugin
      id="com.my.plugin"
      download-size="0"
      install-size="0"
      version="1.0.0"
      unpack="false"/>

The files category.xml (in p2 update-site projects) and MANIFEST.MF (in plugin projects) need to contain the same value.

The question is: How to automate the version number update process in all these files using Maven?

I tried to resolve this problem using maven-release-plugin and maven-versions-plugin. The first plugin makes a lot of unused actions (like making a lot of CVS commits, which I do not use in this project). The second plugin only makes changes in pom.xml files and do not modify feature.xml, category.xml and MANIFEST.MF, or I used it not so good.
