eclipse - Artifact has not been packaged yet

Question

I am letting Maven copy some dependency files into a specific location for a GWT project. The maven-dependency-plugin does the job and so far it works. The only Problem is that I'm getting an error from Eclipse that says:

Artifact has not been packaged yet. When used on reactor artifact, copy should be executed after packaging: see MDEP-187.

I have tried to change the <phase> but that did not work. How can I get rid of that error and why is it there because Maven builds as intended.

<plugins>
  <plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
      <execution>
        <phase>install</phase>
        <goals>
          <goal>copy-dependencies</goal>
        </goals>
        <configuration>
          <outputDirectory>${project.basedir}/war/WEB-INF/lib</outputDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

Answer 1

I got the same error and I solved this issue with a workaround. I have compiled and installed the project with maven in a console outside eclipse ide. After I have refreshed the project inside eclise ide and error has disappeared.
