Why am I receiving a “Plugin execution not covered by lifecycle configuration with GWT” error?

Question

I\'m using STS and I imported a GWT project from another machine. The project uses m2eclipse. I\'m getting these two errors when building the project:

Plugin

If you use Eclipse Indigo (3.7) you have to activate the lifecycle plugin. See here for more details.

Just add this pluginManagement section to your build section of your pom.xml file

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
                <lifecycleMappingMetadata>
