maven-enforcer-plugin警告解决

警告状况描述：
父项目使用插件maven-enforcer-plugin，所有子项目中<parent>标签处均会提示maven-enforcer-plugin (goal "enforce") is ignored by m2e警告信息。
父项目pom.xml

<build>
	<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-enforcer-plugin</artifactId>
			<version>1.0</version>
			<executions>
				<execution>
					<id>enforce-maven</id>
					<goals>
						<goal>enforce</goal>
					</goals>
					<configuration>
						<rules>
							<requireMavenVersion>
								<version>(,2.1.0),(2.1.0,2.2.0),(2.2.0,)</version>
								<message>Maven 2.1.0 and 2.2.0 produce incorrect GPG signatures and checksums respectively.</message>
							</requireMavenVersion>
						</rules>
					</configuration>
				</execution>
			</executions>
		</plugin>
	</plugins>
</build>

警告引发原因：
MyEclipse/Eclipse使用的m2e插件，所以会忽略没有与m2e插件关联的maven插件，从而造成警告信息。

警告解决方法：
为父项目加入lifecycle-mapping插件即可。

<build>
	<pluginManagement>
		<plugins>
			<!-- This plugin's configuration is used to store Eclipse m2e settings 
				only. It has no influence on the Maven build itself. -->
			<plugin>
				<groupId>org.eclipse.m2e</groupId>
				<artifactId>lifecycle-mapping</artifactId>
				<version>1.0.0</version>
				<configuration>
					<lifecycleMappingMetadata>
						<pluginExecutions>
							<pluginExecution>
								<pluginExecutionFilter>
									<groupId>org.apache.maven.plugins</groupId>
									<artifactId>maven-enforcer-plugin</artifactId>
									<versionRange>[1.0.0,)</versionRange>
									<goals>
										<goal>enforce</goal>

								</pluginExecutionFilter>
								<action>
									<ignore />
