Eclipse – Maven GWT (2.5.1) setup issue

I've ran the mvn

   mvn archetype:generate \
     -DarchetypeGroupId=org.codehaus.mojo \
     -DarchetypeArtifactId=gwt-maven-plugin \
     -DarchetypeVersion=2.5.1

As described: http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.html

Then in Eclipse I import the project via "Import Maven Projects"

I get the following error:
gwt-maven-plugin:2.5.1:i18n (1 errors)
No marketplace entries found to handle /pom.xml in Eclipse. Please see Help for more information.

Any suggestions?
