eclipse3.6 配置maven出错！！！！！！！！！！！！！

Question

pom.xml文件中引用插件native2ascii-maven-plugin如下：<plugins><plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>native2ascii-maven-plugin</artifactId>
<version>1.0-alpha-1</version>
<configuration>
<dest>src/main/resources</dest>
<src>src/main/resources/i18n</src>
</configuration>
<executions>
<execution>
<id>native2ascii-utf8</id>
<goals>
<goal>native2ascii</goal>
</goals>
<configuration>
<encoding>UTF8</encoding>
<includes>ApplicationResources.properties, errors.properties, ApplicationResources_*.properties,errors_*.properties</includes>
<excludes>
ApplicationResources_pt*.properties,
ApplicationResources_es*.properties,
errors_pt*.properties,
errors_es*.properties
  </excludes>
</configuration>
</execution>
<execution>
<id>native2ascii-8859_1</id>
<goals>
<goal>native2ascii</goal>
</goals>
<configuration>
<encoding>8859_1</encoding>
<includes>
ApplicationResources_pt*.properties,
ApplicationResources_es*.properties,
errors_pt*.properties,
errors_es*.properties
  </includes>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
但是会出现红叉，出错的位置是在  <execution>错误的具体内容是：Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:native2ascii-maven-plugin:1.0-alpha-1:native2ascii (execution: native2ascii-utf8, phase: generate-resources)紧急！！！！！！！！！！
