maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.

以上错误是MyEclipse2014自带的m2e插件报出来的错误，原因是maven-dependency-plugin配置缺少pluginManagement的配置，代码配置如下：

<properties>
		<project.build.directory>.</project.build.directory>
	</properties>

	<build>
		<resources>
			<resource>
				<directory>src/main/resources</directory>
				<filtering>true</filtering>
				<excludes>
					<exclude>**/*.*</exclude>
				</excludes>
			</resource>
		</resources>

上述错误在m2eclipse插件中是没有的，在m2eclipse插件中编译好的项目移植到m2e中就出了这个问题。
