Citrus framework ftp connection

I'm trying to know better citrus framework for integration tests. I try to create ftp sender but I have following error:

Caused by: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://ift.tt/1dDJqLp]

Offending resource: class path resource [citrus-context.xml]

Here's my part of citrus-context.xml file:

<beans xmlns="http://ift.tt/GArMu6"
   xmlns:xsi="http://ift.tt/ra1lAU"
   xmlns:citrus="http://ift.tt/1pTVYcf"

   <citrus:channel-endpoint id="fileEndpoint" channel="fileChannel"/>
   <file:outbound-channel-adapter id="fileOutboundAdapter" 
                            channel="fileChannel" 
                            directory="file:/"/>
   <si:channel id="fileChannel"/>  

Any idea what am I doing wrong? Thanks from advance.
