This is the code which I had added to my spring project which is not getting started when trying to run with tomcat.
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-amqp</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
Instead of two dependencies add only one dependency as follows.
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-amqp</artifactId>
<version>4.3.5.RELEASE</version>
</dependency>

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.
Here is my maven dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

</dependency>
<dependency>

<artifactId>lettuce-core</artifactId>
<version>5.0.0.RELEASE</version>
</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
Description:
An attempt was made to call the method org.springframework.data.redis.connection.RedisConnection.getConfig(Ljava/lang/String;)Ljava/util/List; but it does not exist. Its class, org.springframework.data.redis.connection.RedisConnection, is available from the following locations:

Please any help is very appreciated,thanks in advance for your reply.
I have spent a whole day to resolve the exactly same issue. And after a whole day R&D, I found the solution.
dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-data-rest')
implementation('org.springframework.boot:spring-boot-starter-web')

// runtimeOnly('mysql:mysql-connector-java')
}
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>
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.
I probably have an issue with my POM in my SpringBoot App.
Currently I am trying to access my Keycloak Server with the
"admin-client-keycloak"
But on the call:
Response response = getInstance().realm(REALM).users().create(user);
I get Error:
java.lang.NoSuchMethodError: javax.ws.rs.core.UriBuilder.resolveTemplates(Ljava/util/Map;)Ljavax/ws/rs/core/UriBuilder;

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:
<dependencies>

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.
It's possible to build a Gradle plugin with Maven. Which dependencies are needed?
Yes, it's possible. We do so with Spring Boot's Gradle plugin using these dependencies:
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.gradle</groupId>
<artifactId>gradle-core</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.gradle</groupId>
<artifactId>gradle-base-services</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.gradle</groupId>
<artifactId>gradle-base-services-groovy</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.gradle</groupId>
<artifactId>gradle-plugins</artifactId>
<scope>provided</scope>
</dependency>
Groovy's in Maven Central, but the Gradle dependencies are in their own repo: http://repo.gradle.org/gradle/libs-releases-local
I have this situation:
I know that "Maven resolves version conflicts with a nearest-wins strategy". So here wins the aop 3.0.7 based on this rule. But i also define a dependencyManagement section in my pom and it seems like this:
<properties>
<org.springframework.version>3.2.4.RELEASE</org.springframework.version>
<org.springframework.security.version>3.1.4.RELEASE</org.springframework.security.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${org.springframework.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${org.springframework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>${org.springframework.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>

<artifactId>jstl</artifactId>

</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.7.1</version>
</dependency>
</dependencies>
</project>
And this is what it all looks like on the dependencies tab:
So i expect the spring-aop to use the 3.2.4.RELEASE version instead of 3.0.7 like the webmvc, as i define this in the dependeny management.. Why is there still being used the older version 3.0.7?
Your dependency management declaration has a typo (com.springframework instead of org.springframework).
This is the correct pom entry:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
Unfortunately, since the dependency is not being used, Maven (or Eclipse) will not flag as a missing artifact.
I was working on a spring mvc maven project and in initial stage I can across this error.
in my servlet-context.xml, I am trying to generate "HibernateTransactionManager" bean which throws me this errr :

I can even locate all my classes in my Maven dependency tree.
I have also tried to externally add a new .jar for spring-orm but that didnt work as well. I have tried to clean build and re-compile several times but that didn't work out.
I would really appreciate any of your inputs.
This is my first SO answer, so please bear with me.
The error generated is “Cannot find class file for org/hibernate/HibernateException”. The POM you have provided lists all the dependencies your project and including a reference to the hibernate-validator jar.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>
If you extract this jar file and search its contents, no class file named HibernateException can be found. This is the root cause of the error and you a repository that contain the HibernateException class file.
As you are using maven, you can see all the repositories related to Hibernate here
http://mvnrepository.com/artifact/org.hibernate
I’ve selected the hibernate-core-4.2.0.Final as core would suggest it has most of the main class files hibernate requires. Downloading and extracting the jar shows that the HibernateException class file exists here.
Therefore, if you update your POM.xml with the following entry
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.2.0.Final</version>
</dependency>
Now you have to make Maven download the repository to your local machine if it doesn’t exist and use it for your project. If you are running the project from Elcipse, do this by right-clicking the project->Run As-> Maven Clean.
Hope this helps.
if you are sure that maven has downloaded the hibernate jar's and are available in/to the jar/war file generated from the build then the issue could be as follows.
sometimes Maven fails to download the complete JAR file from the server, a class not found exception can occur in those cases as well.
to fix this goto .m2 folder in your home directory, delete the hibernate jar's and make a clean install. this will download the new set of files and things should start to work.
you can check if the files were downloaded correctly by opening them as a zip file jar tf jar-file.jar
