如何在Maven和Tycho中保持插件清单版本和pom版本同步

I am using Maven with Tycho to build an eclipse plugin. Tycho generates the pom.xml file for Maven by inspecting the manifest file of the plugin.

This is because I have done some customization in the generated pom file and cannot overwrite it every time I change the version in the manifest.I am using Maven with Tycho to build an eclipse
