Hi.

When I not have the artifacts of M2 GWT Plugin (1.1-SNAPSHOT) in my local 
repository and try clean and install (both goals at same time) using Maven 
Integration for Eclipse I got the following error:

Maven cannot calculate your build plan, given the following information:

Tasks:
- clean
- install

Error message: Failed to load plugin descriptor for: 
org.codehaus.mojo:gwt-maven-plugin:1.1-SNAPSHOT:compile. Cannot discover it's 
default phase, specified in its plugin descriptor.
Root error message: Unable to download the artifact from any repository

Using same project (pom.xml) executing Maven from command prompt (mvn clean 
install) the artifacts are downloaded from remote repository and installed into 
my local repository and build done successfully. After that then I get success 
running it into Eclipse too.

In my pom.xml I have configured

  <!-- Repositories -->
  <repositories>
    <repository>
      <id>mojo_snapshots</id>
      <url>http://snapshots.repository.codehaus.org</url>
      <snapshots>
        <enabled/>
      </snapshots>
    </repository>
  </repositories>
  
        <!-- include the GWT-Maven repo as plugin, and as standard -->
        <pluginRepositories>
                <pluginRepository>
                        <id>mojo-plugins-snapshots</id>
                        <url>http://snapshots.repository.codehaus.org</url>
                </pluginRepository>
                <pluginRepository>
                        <id>gwt-maven</id>
                        <url>
                                
http://gwt-maven.googlecode.com/svn/trunk/mavenrepo
                        </url>
                </pluginRepository>
        </pluginRepositories>  

and I´ve configured the plugin in build session:

    <plugins>
      <!-- GWT Maven Plugin -->
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>gwt-maven-plugin</artifactId>
        <version>${gwt.plugin.version}</version>

        <executions>
          <execution>
            <goals>
              <goal>compile</goal>
              <!-- <goal>generateAsync</goal> -->
              <!-- <goal>test</goal>  -->
            </goals>
          </execution>
        </executions>
      </plugin>


      <!-- Maven Compiler Plugin -->
      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${maven.compiler.version}</version>
        <configuration>
          <source>${maven.compiler.source}</source>
          <target>${maven.compiler.target}</target>
        </configuration>
      </plugin>
    </plugins>

More a detail: My GWT project is a module from a parent project.

I have added a .rar file containing the entire project.
