Maven GWT (2.5.1) setup issue - eclipse

Question

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?

Answer 1

Add the following to your pom.xml
<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings
only. It has no influence on the Maven build itself. -->
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.codehaus.mojo</groupId>
<artifactId>
gwt-maven-plugin
</artifactId>
<versionRange>
[2.5.1,)
</versionRange>
<goals>
<goal>i18n</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore></ignore>
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>
It will tell eclipse to ignore this error.
