- cvc-elt.1: Cannot find the declaration of element 'beans'

I am using Spring 4.1.4, While creating oauth security configuration file I got this error. So far I am done with :

mvn clean, mvn compile, checked spring-beans jar is in the classpath,

Multiple annotations found at this line: - Class 'org.springframework.security.core.authority.AuthorityUtils' is abstract - cvc-elt.1: Cannot find the declaration of element 'beans'.

Can anyone help me understand the problem here?

Here is my oauth configuration file code :

<beans xmlns:xsi="http://ift.tt/ra1lAU"    xmlns:oauth2="http://ift.tt/1bBHntb"    xmlns:beans="http://ift.tt/GArMu6"   xmlns:security="http://ift.tt/1c8inpe"     xsi:schemaLocation="http://ift.tt/1bBHntb http://ift.tt/1npXF0a         http://ift.tt/1c8inpe http://ift.tt/SiGWZH       http://ift.tt/GArMu6 http://ift.tt/1CZCNBy">
