Also I check this.
I think there is a conflict on spring-plugin-core
How can fix this?

Cause
When this error is displayed:
The following method did not exist:
'org.springframework.plugin.core.PluginRegistry org.springframework.plugin.core.PluginRegistry.of(java.util.List)'
It means spring-plugin-core 1.2.0 is in effect. This is good for springfox-swagger2 v2.9.2, however, some other components can't find PluginRegistry.of(java.util.List) in spring-plugin-core, because it is defined in a later version.
When this error is displayed:
The following method did not exist:
'org.springframework.plugin.core.Plugin org.springframework.plugin.core.PluginRegistry.getPluginFor(java.lang.Object, org.springframework.plugin.core.Plugin)'
It means spring-plugin-core 2.0.0 is in effect. This time, springfox-swagger2 v2.9.2 runs into problem because PluginRegistry.getPluginFor(java.lang.Object, org.springframework.plugin.core.Plugin) is removed from this version.
Solution
You may resolve this issue by using the snapshot version of springfox library. It has been upgraded to use the newer version of spring-plugin-core.
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>3.0.0-SNAPSHOT</version>
</dependency>
Please add the repository definition in order to use this snapshot version:
<repositories>
<repository>
<id>jcenter-snapshots</id>
<name>jcenter</name>
<url>http://oss.jfrog.org/artifactory/oss-snapshot-local/</url>
</repository>
</repositories>
Please also replace #EnableSwagger2 with #EnableSwagger2WebMvc.

Spring Plugins version is low, add this to pom.xml.
<dependency>
<groupId>org.springframework.plugin</groupId>
<artifactId>spring-plugin-core</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
you can find similar issue here: https://github.com/springfox/springfox/issues/2968

In my case I just upgrade my swagger version, and it worked.
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>3.0.0</version>
</dependency>

I faced the same problem and this is what worked for me-
1.Use HAL explorer instead of HAL browser
2.Update springfox dependency version
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-explorer</artifactId>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>

either run maven dependency tree command to see that which two jars are included and remove one or an easier way is to delete .m2 folder and re import the dependencies it will fix the issue.

Executing spring web client causing DeferringLoadBalancerExchangeFilterFunction non qualifying bean exception

I have created spring boot project with Spring WebFlux. Idea is to learn the Spring WebClient and related stuff. On start of application, I am getting below error
Error creating bean with name 'loadBalancerWebClientBuilderBeanPostProcessor' defined in class path resource [org/springframework/cloud/client/loadbalancer/reactive/LoadBalancerBeanPostProcessorAutoConfiguration.class]:

I have dependencies like spring-cloud-dependencies/spring-boot-starter*/spring-cloud-context in my maven dependencies. Error just giving information that DeferrringLoadBalancerExchangeFilterFunction is not available, I have tried to inject it using #Bean in my configuration class. But error still persists.

Please note that i use feign client as well as web client in my code. Not sure whether that has an impact
Adding dependency to org.springframework.cloud:spring-cloud-starter-loadbalancer helped in my case, as adviced by #OlgaMaciaszek
Looks like I faced the problem with similar root cause.
To use Spring Cloud with Spring Boot you have to respect versions compatibility.
I had a project based on Spring Boot (2.3.12.RELEASE) and Spring Cloud (Hoxton.SR11) which is fine.
But I also tried to use the latest version of com.playtika.reactivefeign:feign-reactive:3.0.3 which actually relies on Spring Cloud (2020.0.x)
As a result I've faced the same error
Error creating bean with name 'loadBalancerWebClientBuilderBeanPostProcessor'`
In my case I've downgraded reactivefeign version to 2.0.31
I have resolved this by removing unnecessary dependency which was causing issues for this issue that is :
'org.springframework.cloud.client.loadbalancer.reactive.DeferringLoadBalancerExchangeFilterFunction' that could not be found.

Redis connection is failed

I'd like to work with Redis for manipulating sessions.But I get failure when running the spring boot app.So I guess that this error is coming from maven dependencies especially version conflicts.

</dependency>
</dependencies>
Notice that I added two dependencies in above pom.xml which there artifactId are spring-session-data-redis and lettuce-core.These dependencies are respectively responsible for Redis connection and ensuring thread safety for session connections.
When I run the spring boot app, I get the belowed error:
APPLICATION FAILED TO START

I have spent a whole day to resolve the exactly same issue. And after a whole day R&D, I found the solution.

Use 'spring-boot-starter-data-redis' and 'spring-session-data-redis'.
Remove lettuse dependency as it is included in spring-boot-starter-data-redis as dependency.
Here is your dependencies:

<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>
Simply delete the explicit version for spring-session-data-redis and go with the version from the spring boot parent pom.
If you want to change the version of spring-session-data-redis, you have to ensure that none of the transitive dependencies is managed by the parent pom. If I downgrade to version 1.3 (version 1.7 could not be found) I end up with the following version mismatch as revealed by mvn -X dependency:tree:
[ESC[1;36mDEBUGESC[m] org.springframework.session:spring-session-data-redis:jar:1.3.3.RELEASE:compile
[ESC[1;36mDEBUGESC[m] org.apache.commons:commons-pool2:jar:2.5.0:compile (version managed from 2.4.2)
[ESC[1;36mDEBUGESC[m] org.springframework.data:spring-data-redis:jar:2.0.10.RELEASE:compile (version managed from 1.7.10.RELEASE)
Please replace the dependency
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
with
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
The version management is done automatically and the started will initialize the redis cache.

As its mentioned in your error the problem is with your configuration.
Following line,
spring.datasource.driver.class-name=oracle.jdbc.driver.OracleDriver
should change as,
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
Note that its not driver.class-name, instead its driver-class-name

spring.datasource.username=system
spring.datasource.password=pw
Try on the project directory pom.xml file in in command promt or your ide.
mvn clean install
I have the same probleme

As we could see the respective versions used are Java (1.8), Jasper Reports(6.6.0) and Spring boot (2.0.3.RELEASE).
Is there anything we have been missing or added extra as a dependency?
Or is it the sequence of dependencies which is affecting the proper import?
Finally figured it out What's New in Spring Framework 5.x as per the documentation
Removed Packages, Classes and Methods
Dropped support: Portlet, Velocity, JasperReports, XMLBeans, JDO, Guava.
Recommendation: Stay on Spring Framework 4.3.x for those if needed.
Might help anyone else also. Thank you.

To be honest: I am not a Maven expert and stitched it together from several web soultions and I expect that some parts are still outdated or something.
the POM dependecys:

The Error occurs from the 'keycloak-admin-client' module.
Now the main question is:
Whats the problem? Or is it realy a bug inside the version of 'keycloak-admin-client'?
I guess not which leads my to a second question:
How can I found out what I need to change in a situation like this?
Thanks in advance for all suggestions. I primary want to learn how to solve such issues by my own in future.
Kind regards
Gregor
EDIT:
Well I am a step further but the issue is still there.
The POM I show you here is a POM of library which is used in other projects.
These Project have a 'spring-Boot-starter' which are using the 'jersey' version:1.54.
So the problem seems clear.
I added the 'jersey 2.0.2' dependency in the final project POM
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jersey</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
But the issue still exists.
How can I force maven use the 2.0.2 version and override the 1.5.?
Only adding the dependecy doesnt seems to help.
Some of the other dependencies are using a different version of the lib jsr311-api. In my case it was the eureka client. I just added an exclude with this dependency in the pom and it worked
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<exclusions>
<exclusion>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
</exclusion>
</exclusions>
</dependency>
Please make sure UriBuilder class exist on your project. And make sure only one UriBuilder class (version) exist in your project. (It can be multiple on your project with different versions.) Different versions can be overlapped.
keycloak-admin-client version should same with your keycloak server version.
add additional dependency to pom (versions must be added, for keycloak 3.0.0.Final => resteasy dependecies 3.5.0.Final works for me. Dependencies must be complied.)
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-admin-client</artifactId>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson2-provider</artifactId>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-multipart-provider</artifactId>
</dependency>
Note: This is my suggestion, if you are develop multi-layer app. You can divide your project to layers. You can divide your spring boot starter app and keycloak access layer. And use this new project as dependecy.
edit,
see Failed adding user by keycloak-admin-client to Keycloak due to "unknown resource"
i hope these can helps.
