My Google Alerts just sent me this and I though it might be worth sharing:
The Eclipse plugin will create/change the .springBeans and the .settings/org.springframework.ide.eclipse.core.prefs. Then you can refresh the Eclipse project (F5) from now the project contains a Spring-Builder which will handle the …#
The same approach should work for the .springWebflow descriptor file.
Furthermore there is IDE-603 to create a Maven plugin that can create those files.
At Q4E (Maven integration for Eclipse) we added extension points so other plugins (ie Spring IDE) can contribute behavior to the Maven project import so you don’t need to use the maven-eclispe-plugin in your pom anymore
FWIW, m2eclipse also provides project configuration extension points. You can read more about them on the wiki at http://docs.codehaus.org/display/M2ECLIPSE/Extensible project configuration framework
