Eclipse中的项目没有Maven Dependencies 这个library的解决办法：Maven Dependencies 这个library在.classpath文件中是这么标记的:

<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">

    <attributes>

        <attribute name="maven.pomderived" value="true"/>

    </attributes>

</classpathentry>

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">

    <attributes>

        <attribute name="maven.pomderived" value="true"/>

     </attributes>

</classpathentry>
