What is the simplest pluginManagement section on can add to a pom to get m2e and eclipse indigo to play together? - m2e

Question

I have read the discussions on this topic but I don't see a simple solution.
Given the following really simple pom.xml, Indigo Eclipse and m2e (version 0.14.0.201107060316), eclipse complains with
Multiple annotations found at this line
- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:2.4.3:resources (execution: default-resources, phase: process-resources)
- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:2.4.3:testResources (execution: default-testResources, phase: process-test-resources)

</project>
I know it has something to do with adding a section as shown in http://wiki.eclipse.org/M2E_plugin_execution_not_covered#execute_plugin_goal
I thought adding the following section to the pom.xml would clear at least one error, but it didn't so I must not have a clear understanding of what is wrong.
Any advice? I'm sure this is simple for some of you.

Answer 1

I face the same problem (Eclipse Indigo, Maven 3.0.2). I solved it following the steps indicated here:
http://code.google.com/p/google-web-toolkit/wiki/WorkingWithMaven
I installed the following features (use eclipse->Help->Install New Software):
- Maven Integration for Eclipse
- Maven Integration for WTP
from here:
http://download.jboss.org/jbosstools/updates/m2eclipse-wtp
Once I installed these features I update the project (rightclik on the project->Maven->Update project..). This worked for me. I hope this can help.
