Spring-Data-Cassandra causes XSD validation error using XML configuration - cassandra

Question

Heyy hello, I have some kind of error that won't affect on my project's compilation,deployment and running But it shows red mark at my configuration file for Spring-data-Cassandra also shows problem in problems menu.
Can any one please tell what's the issue?
I have seen same question related to spring-data-JPA and Spring-data-* but they are not helping so I am posting this one.
here is error message:-
The errors below were detected when validating the file "spring-tool.xsd" via the file "application-config.xml". In most cases these errors can be detected by validating "spring-tool.xsd" directly. However it is possible that errors will only occur when spring-tool.xsd is validated in the context of application-config.xml.
The errors below were detected when validating the file "spring-beans.xsd" via the file "application-config.xml". In most cases these errors can be detected by validating "spring-beans.xsd" directly. However it is possible that errors will only occur when spring-beans.xsd is validated in the context of application-config.xml.
Here is my config.xml file and pom file
