eclipse maven plugin execution not covered by life cycle configuration

在向eclipse导入一个Maven工程时，pom.xml报错了：

<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>

错误原因是：

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-dependency-plugin:2.6:copy (execution: default, phase: validate)

googling了一下：

找到了如下解决方案：

之前结构：

<build>

        <plugins>

            <plugin> ... </plugin>

            <plugin> ... </plugin>

                  ....

        </plugins>

</build>

修改后结构

<build>

    <pluginManagement>

        <plugins>

            <plugin> ... </plugin>

            <plugin> ... </plugin>

                  ....

        </plugins>

    </pluginManagement>

</build>
