I've been playing around with spring boot and stumbled onto a guide about embedding Keycloak into a Spring Application, I thought this would a fun little project so I have been following This guide.
I have implemented everything and the project is building, but crashing at start. This is the error:
java.lang.NoSuchMethodError: 'org.infinispan.configuration.global.GlobalJmxStatisticsConfigurationBuilder org.infinispan.configuration.global.GlobalConfigurationBuilder.globalJmxStatistics()'
I've searched around for a bit and haven't had much luck. I've tried messing around with the dependencies to see if I am missing something, I have also verified that I can import org.infinispan.configuration.global.GlobalConfigurationBuilder; which is available, so could be version conflicts? Any help would be appreciated.

That is it, essentially. It all starts with…
…
<parent>

<version>2.3.4.RELEASE</version>

You upgrading from Baeldung's original 2.2.6.RELEASE of Spring Boot to 2.3.4.RELEASE, caused a whole cascading domino affect of incompatible dependencies.
Unless you desperately need to be on 2.3.4, my advice is to just roll back to 2.2.6.RELEASE. Or else you'll need a machete as long as your arm to hack your way through the tangled morass of incompatible dependencies that results from that upgrade.
I've pushed this working demo to confirm that 2.2.6.RELEASE at least works with JDK 15.
I have the same issue.
The maximum versions i have updated in my pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.12.RELEASE</version>
<relativePath />

<!-- check keycloak-dependencies-server-all effective pom -->
<infinispan.version>10.1.8.Final</infinispan.version>
<resteasy.version>3.12.1.Final</resteasy.version>
</properties>
I have tried to update the keycloak to any versions more than 11.0.4 version and the spring boot more than 2.3.12.RELEASE but it's impossible - incompatible versions. Maybe who knowns how to update?

I trying to setup the TimeTable example from OptaPlanner (link here) from copying the needed dependency for Maven and all the relevant code. However, when I try to run it, error occur.
Side note, I trying to copy over the TimeTable to our existing Java Spring Boot version 2.4.5 project.

Take a look at this suggestion from the stacktrace you pasted, I suspect that will fix it:
Trying to install the Hal Browser with Spring Boot, but I get the following error:

I wonder if there is an official reference for compatibility between Spring plugins, but anyway, here I used the latest versions by default.

The package was renamed to spring-data-rest-hal-explorer. I verified that it's compatible with Spring Boot 2.5.6.
Maven example:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-explorer</artifactId>
</dependency>
Gradle example:
implementation('org.springframework.data:spring-data-rest-hal-explorer')
It looks like an incompatibility issue with the latest version of Spring, the solution is to downgrade Spring Boot to 2.3.5.RELEASE

But When I create new project there is comes from right place. I've got question How I can figure it out call from right place instead of coming from wrong place. Thank you guys in advance
#GetMapping(value = "get")
public ResponseEntity<List<BssClient>> get(){
// cardStatement.CardStatement()
List<BssClient> list = dataBase.findAllBssClient();
return ResponseEntity.ok(list);

i have also faced this problem so we can't use concurrently spring-boot-starter-web and spring-boot-starter-jersey because glassfish is part of jersey so just remove any one dependency from both of them in my case i removed starter-jersey

finally problem has been gone please try it
You should add the packaging to war at the pom.xml:
<packaging>war</packaging>
It seems something wrong with your dependencies : can you check this typo
tomcat-embed-jasper dependency
providet
Other question why you have two dependencies if you are using tomcat one will be fine.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>providet</scope>
</dependency>
check that example pom
spring boot web dependency is enough it already includes tomcat. You don't need to explicitly define tomcat dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
If it is a new project i would try to run a standard project generated on: https://start.spring.io/. This way you can be sure the project should be runnable and any failure is to blame on anything other than the project or IDE. If that does not run i would reinstall Tomcat.
QUESTION
In a Spring Boot Java application built with Maven using the spring-boot-maven-plugin with WAR packaging through Eclipse IDE with M2 with the goal as clean package, I would like to know if there is a command which would allow me to copy the resource folders (css, images, etc) which currently end up in mywar.war/WEB-INF/classes/static/ into the root directory mywar.war, so that I have mywar.war/images/, etc?
I see that with other plugins, there is something like a targetPath, but I can't find anything like that in the documentation for spring-boot-maven-plugin.

So, I ended up getting around this by moving all of my resources from the /src/main/resources/static directory into a /src/main/webapp directory. Then everything appeared right under the root of the resulting WAR file, and the Apache HTTP Server picked them up and allowed them through.
Thanks for your insight, everyone!
Everything will work as expected. Spring Boot will server your static content.
The urls will be
<host>:<port>/<warname>/css
<host>:<port>/<warname>/images
etc.
