Fix Maven dependency conflicts without upgrading the old existing dependencies

I am using spring framework 4.2.9.RELEASE and redis 1.7.6.RELEASE

<dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-redis</artifactId><version>1.7.6.RELEASE</version></dependency>

lately I had to add a dependency that uses redis 2.2.2.RELEASE that needs Spring 5 , So I am getting dependency conflicts, And I cant upgrade my project to spring 5 and redis 2

what should I do
