打开navigator,修改下面的classpath文件:

将<classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER">改成:

       <classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER">
		<attributes>
			<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
		</attributes>
	</classpathentry>
