So, you had been using Snakeyaml with an earlier Spring Boot version, but with a newer Spring Boot version, Snakeyaml stopped working. This very much seems to be a version incompatibility issue.
Here: https://search.maven.org/artifact/org.springframework.boot/spring-boot-starter/2.1.15.RELEASE/jar
we can see this structure:

where the interesting part from our perspective is:
<artifactId>snakeyaml</artifactId>
<version>1.23</version>
so, you will likely need to ensure that your Snakeyaml version is 1.23.

We can create a software solution for the above case by separating the above functionalities in three objects as below. 1) The Snake Box Factory The factory will produce the Snake Boxes. The factory could be

I searched a lot and tried many solutions but no success .
Should I add spring-core or spring context separately in pom file ?
How can I check which spring-core is matched for spring boot 2.6.6?
Any advice to fix this?

The issue is indeed with spring-core jar.If you see the version of spring-core that is shown in dependency tree its 5.2.4.
https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/metrics/ApplicationStartup.html
If we see this javadoc, this class is since 5.3 spring framework version, so its not found.
I would recommend you to add starter dependencies in your pom.
eg:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
</dependencies>
and so on. These dependencies will then be fully available in compile classpath + fetch all transitive dependencies.
Eg same graph for me looks like:
+--- org.springframework.boot:spring-boot-starter-actuator -> 2.6.3
| +--- org.springframework.boot:spring-boot-starter:2.6.3
| | +--- org.springframework.boot:spring-boot:2.6.3
| | | +--- org.springframework:spring-core:5.3.15
| | | | \--- org.springframework:spring-jcl:5.3.15
| | | \--- org.springframework:spring-context:5.3.15
| | | +--- org.springframework:spring-aop:5.3.15
| | | | +--- org.springframework:spring-beans:5.3.15
| | | | | \--- org.springframework:spring-core:5.3.15 (*)
| | | | \--- org.springframework:spring-core:5.3.15 (*)
| | | +--- org.springframework:spring-beans:5.3.15 (*)
| | | +--- org.springframework:spring-core:5.3.15 (*)
| | | \--- org.springframework:spring-expression:5.3.15
| | | \--- org.springframework:spring-core:5.3.15 (*)
| | +--- org.springframework.boot:spring-boot-autoconfigure:2.6.3
| | | \--- org.springframework.boot:spring-boot:2.6.3 (*)
| | +--- org.springframework.boot:spring-boot-starter-logging:2.6.3
| | | +--- ch.qos.logback:logback-classic:1.2.10
| | | | +--- ch.qos.logback:logback-core:1.2.10
| | | | \--- org.slf4j:slf4j-api:1.7.32 -> 1.7.33
| | | +--- org.apache.logging.log4j:log4j-to-slf4j:2.17.1
| | | | +--- org.slf4j:slf4j-api:1.7.25 -> 1.7.33
| | | | \--- org.apache.logging.log4j:log4j-api:2.17.1
| | | \--- org.slf4j:jul-to-slf4j:1.7.33
| | | \--- org.slf4j:slf4j-api:1.7.33
| | +--- jakarta.annotation:jakarta.annotation-api:1.3.5
| | +--- org.springframework:spring-core:5.3.15 (*)
| | \--- org.yaml:snakeyaml:1.29
....
Note: Even spring-web,data jpa dependencies fetch spring core so do not worry, just ensure you add them in pom to get things running.

Spring boot application fails to start with javax.validation.BootstrapConfiguration error

I am developing a simple spring boot web enabled application. Spring boot Version is 2.2.1. When I start application I am getting this error
***************************
APPLICATION FAILED TO START
***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.hibernate.validator.internal.xml.config.ValidationBootstrapParameters.<init>(ValidationBootstrapParameters.java:63)
The following method did not exist:
javax.validation.BootstrapConfiguration.getClockProviderClassName()Ljava/lang/String;
The method's class, javax.validation.BootstrapConfiguration, is available from the following locations:
jar:file:/home/shantanu/.m2/repository/io/swagger/swagger-codegen-cli/2.3.0/swagger-codegen-cli-2.3.0.jar!/javax/validation/BootstrapConfiguration.class
jar:file:/home/shantanu/.m2/repository/javax/validation/validation-api/2.0.1.Final/validation-api-2.0.1.Final.jar!/javax/validation/BootstrapConfiguration.class
jar:file:/home/shantanu/.m2/repository/jakarta/validation/jakarta.validation-api/2.0.1/jakarta.validation-api-2.0.1.jar!/javax/validation/BootstrapConfiguration.class
It was loaded from the following location:
file:/home/shantanu/.m2/repository/io/swagger/swagger-codegen-cli/2.3.0/swagger-codegen-cli-2.3.0.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of javax.validation.BootstrapConfiguration
I have no idea what is causing this error. I even tried putting exclusions for javax.validations on multiple dependencies but nothing helped. Here's the POM dependency tree. Please help.

It looks like you have both have:
jakarta.validation:jakarta.validation-api
(transitive dependency via org.springframework.boot:spring-boot-starter-validation)
and
javax.validation:validation-api
on your classpath.
Since Spring Boot 2.2: Java EE dependencies with a javax. group ID are replaced by the equivalent Jakarta EE dependencies with a jakarta. group ID in Spring Boot’s starters.
For more information check the release notes:
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.2-Release-Notes#jakarta-ee-dependencies
So you can remove the javax.validation:validation-api dependency from your project.

CXFServlet throws java.lang.NoSuchMethodError: org.codehaus.stax2.ri.EmptyIterator.getInstance()Lorg/codehaus/stax2/ri/EmptyIterator;

I'm using Java 11, Spring Boot 2.1.1 and Apache CXF 3.2.7 to expose a SOAP web service that imports an XSD schema. In the WSDL it shows like:
<wsdl:import location="http://localhost:9000/endpoint/ws?wsdl=WS_endpointSoapPort.wsdl" namespace="http://test.com"> </wsdl:import>
When I send a query it fails with the following stack:
2018-12-31 12:05:54,908 ERROR se.[Tomcat].[localhost].[/].[CXFServlet]: 175 - Servlet.service() for servlet [CXFServlet] in context with path [] threw exception [Servlet execution threw an exception] with root cause
java.lang.NoSuchMethodError: org.codehaus.stax2.ri.EmptyIterator.getInstance()Lorg/codehaus/stax2/ri/EmptyIterator;
Any thoughts?

I had a conflict on the org.codehaus.woodstox:stax2-api which was included in version 3.1.4 within org.apache.cxf:cxf-core and in version 4.1 within com.sun.xml.ws:rt. I solved the conflict by removing the library using Maven excludes:
<exclusions>
<exclusion>
<groupId>org.codehaus.woodstox</groupId>
<artifactId>stax2-api</artifactId><!-- 4.1 conflicts with 3.1.4 from apache cxf-spring-boot-starter-jaxws-->
</exclusion>
</exclusions>

After research in deeply, I found the following JIRA that mentions a problem with Stax2 version. BTW the ticket said that it resolves with the version that I'm using.
In the end, I fixed upgrading to woodstox-core-5.2.0. In fact, the library mentions a similar problem that was solved in that version. Details here.

I run into the same problem and upgrading to CXF 3.2.7 or later fixed the issue for me.

The key is likely in your mvn:dependency-tree output. In my case:
[INFO] \- org.apache.cxf:cxf-rt-ws-security:jar:3.3.6:compile
[INFO] +- org.apache.cxf:cxf-core:jar:3.3.6:compile
[INFO] | \- com.fasterxml.woodstox:woodstox-core:jar:5.3.0:compile (version managed from 5.0.3)
[INFO] | \- org.codehaus.woodstox:stax2-api:jar:4.2:compile
[INFO] \- org.apache.wss4j:wss4j-policy:jar:2.2.5:compile
[INFO] \- org.apache.neethi:neethi:jar:3.1.1:compile
[INFO] \- org.codehaus.woodstox:woodstox-core-asl:jar:4.4.1:compile
[INFO] \- (org.codehaus.woodstox:stax2-api:jar:3.1.4:compile - omitted for conflict with 4.2)
org.apache.cxf:cxf-rt-ws-security:jar:3.3.6 leads to both version 3.1.4 and version 4.2 of stax2-api because of the very much outdated woodstox-core-asl dependency (from 2014). I will have to see if I can get rid of this, because it leads to the NoSuchMethodFoundError described above.

the problem is in new version of stax2-api new methods added. you can solve the problem by adding new version of the stax2-api. in my case adding
<dependency>
<groupId>org.codehaus.woodstox</groupId>
<artifactId>stax2-api</artifactId>
<version>4.2.1</version>
</dependency>
solved the problem.

This is the "jar hell problem".
You should use the exclusions clause that was mentioned Julien Kronegg.
Sorry for the previous answer that I have deleted.

Maven transient dependency (library/jar vaadin json) is not being excluded

I have the problem that maven is including 2 versions of the org.json package from two different dependencies.
I have the following:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
But I also have the following outputs ( vaadin is the one I don't want ):
[INFO] +- org.springframework.boot:spring-boot-starter-test:jar:2.0.3.RELEASE:test
The dependency tree is showing the following two entries:
[INFO] +- org.springframework.boot:spring-boot-starter-test:jar:2.0.3.RELEASE:test

AND
[INFO] +- org.json:json:jar:20171018:compile
I have tried the following but the annoying vaadin jar is still being included in the project:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
<dependency>
<groupId>org.mbak.test</groupId>
<artifactId>mb-cloud-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>com.vaadin.external.google</groupId>
<artifactId>android-json</artifactId>
</exclusion>
</exclusions>
</dependency>
This is causing a method not found exception.
If we go and delete the JAR from the packaged war manually, everthing is fine!

[INFO] BUILD SUCCESS
And because of vaadin I was getting:
org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.json.JSONObject.entrySet()Ljava/util/Set;
at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1006)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:742)
Update
I tried the following but it still doesn't fail to exclude vaadin:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>com.vaadin.external.google</groupId>
<artifactId>android-json</artifactId>
</exclusion>
</exclusions>
</dependency>
Additionally, I am noticing the behavior is different when you do mvn spring-boot:run and when you run a packaged war file.
When running the packaged war file we have the error. When we do spring-boot:run we do not.
Weird fix
A colleague of mine fixed this by entering the following exclusion ( but I don't understand why it worked ):
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
<exclusions>
<exclusion>
<groupId>com.vaadin.external.google</groupId>
<artifactId>android-json</artifactId>
</exclusion>
</exclusions>
</dependency>
Anyone got any ideas?

Dependency still on classpath after Gradle dependency exclusion

You can specify the version which you want to use with dependency org.json and use that dependency above the one which you don't want.
