I have a Spring Boot 2.5.4 application in which I would like to add Redis and access it via Spring Data Redis. My current configuration looks like this:

for current configuration while application start I am receiving

So far I have tried manipulating the redis.clients and spring-boot-starter-data-redis versions by decreasing and increasing it but always problems with initialization occur. Every single tutorial which I found doesn't contain configuration for the new Spring Boot application version. I Will be grateful for suggestions on how to manipulate the pom.xml version of redis.clients and spring-boot-starter-data-redis to make the application starts again.
spring-boot-starter-data-redis already includes jedis as a dependency so you shouldn't add it to your pom.xml with a version that might not be compatible with your spring-boot-starter-data-redis.
In the case of spring-boot-starter-data-redis version 2.5.0, it includes jedis version 3.6.3 but you override this with version 3.1.0, which might not be compatible with spring-boot-starter-data-redis version 2.5.0.
Always check the dependencies already included in the Spring Boot Starters because incompatibilities are exactly what they try to avoid.
Having said all that, I am not completely sure that this will solve the issue, but it is a good place to start.
Update 26/01/2022
The spring-boot-starter-data-redis dependency pom.xml includes the following dependency:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>2.5.1</version>
<scope>compile</scope>
</dependency>
This spring-data-redis dependency pom.xml already includes jedis version:
<properties>
(...)
<jedis>3.6.0</jedis>
(...)
</properties>
And the dependency itself:
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>${jedis}</version>
<optional>true</optional>
</dependency>
This means that you should only add the dependency to your pom.xml but set no version so that the one set in spring-data-redis is used as follows:
<dependencies>
(...)
<!-- OTHER DEPENDENCIES -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
(...)
<!-- OTHER DEPENDENCIES -->
</dependencies>
