我让Maven将一些依赖文件复制到GWT项目的特定位置.它maven-dependency-plugin完成了工作,到目前为止它的工作原理.唯一的问题是我从Eclipse那里得到一个错误:

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

我试图改变<phase>但是没有用.我怎样才能摆脱这个错误,为什么它会在那里因为Maven按照预期构建.

<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>
