Failed to destroy end point associated with ProtocolHandler ["ajp-nio-8009"] while starting the Tomcat server after changing pom.xml

I am working on a legacy application which is using Struts-1 and Hibernate-4. Now I have introduced Spring-Boot in the application. Below is the pom.xml that I have now ,-

Now while I'm starting the Tomcat server in eclipse [Tomcat-8.0 or Tomcat-9.0], it doesn't start at all. And I'm getting the below error everytime in the console ,-

Can anyone please help, how I can startup the Tomcat server and run the application as usual like before??
I got some suggestions from here:
Tomcat: Failed to destroy end point associated with ProtocolHandler
But neither of them actually work for me. Kindly suggest.
Edit : please find the screenshot below ,-

How to solve "java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.accessibleConstructor"

I'm replacing lagecy's gradle project with boot's maven project.
There is no error, but when i run Tomcat server, the following error is
displayed.
i tried these....
pom.xml spring-context remove -> failed
spring boot version downgrade 2.1.9 --> 2.0.4 -> failed
i made dependency spring core, spring context same version -> failed

How should it work?

I suggest that you run the following at command line
mvn dependency:tree -Dincludes=org.springframework.*
You should then look at all the spring dependency versions. I'm guessing you have some version mismatches which you'll need to fix.

Posting this because my solution was different and took forever to find.
In my case it seemed to have been a conflict in multiple dependencies having that method.
By grepping my project folder for the name of the method, I could see what jars it was present in.
grep -r "ReflectionUtils" myProjectDirectory/
Result: (only listing spring ones)
Binary file myProjectDirectory//target/myProjectDirectory/WEB-INF/lib/spring-core-5.3.15.jar matches
Binary file myProjectDirectory//target/myProjectDirectory/WEB-INF/lib/org.springframework.core-3.2.4.jar matches
I used mvn dependency:tree to track where org.springframework.core-3.2.4.jar was coming from, and it was under a dependency called "org.springframework.beans"
I went to pom.xml and removed the springframework.beans dependency, replaced with spring-beans 5.3.9, clean installed, and reran grep. Result was now:
Binary file myProjectDirectory//target/myProjectDirectory/WEB-INF/lib/spring-core-5.3.15.jar matches
From there I ran on tomcat and issue no longer appeared. It may be a unique circumstance but it was the only thing I could get to work after scouring threads everywhere.

When doing deploy of my application using spring with swagger2

When doing deploy of my application using spring with swagger2 I get the following error:
Message icon - Error An error occurred during activation of changes, please see the log for details.
Message icon - Error java.lang.NoSuchMethodError: com.google.common.base.Optional.transform(Lcom/google/common/base/Function;)Lcom/google/common/base/Optional;
Message icon - Error com.google.common.base.Optional.transform(Lcom/google/common/base/Function;)Lcom/google/common/base/Optional;
Has anyone here been through this?

Maven: slf4 jars with different versions are added after pom compile, and war gets version conflict error because of that

I am having issue with my pom. Even when I am not adding any dependancy in the pom, in war I am getting:
1. slf4j-api-1.5.11.jar
2. slf4j-api-1.6.1.jar
3. slf4j-log4j12-1.6.1.jar
Issue: due to this My war doesn't run on the server and gets error regarding conflict. I need to resolve this issue.
Manual Solution: I remove the slf4j-api-1.5.11.jar manually from the war and it starts running on the server.
Can you please help me to avoid this manual solution and My pom is it self handles it. I also used exclusion, but of no vain.
looking forward to your help

You can use dependency management to ensure that every slf4j dependencies are aligned.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-IMPL-THAT-YOU-WANT</artifactId>
<version>1.7.12</version>
</dependency>
</dependencies>
</dependencyManagement>
To know which dependency requires and import slf4j, you can use:
mvn dependency:tree -Dverbose

While YMomb's answer should work (and its easy), you can also explicitly exclude transitive dependencies from a dependency.
To find which dependencies consist org.slf4j as a transitive dependency, run
mvn dependency:tree -Dincludes=org.slf4j:*
This will give you something like , ( at least it gave me from above of your dependencies)
[INFO] - org.quartz-scheduler:quartz:jar:2.1.7:compile [INFO]
org.slf4j:slf4j-api:jar:1.6.1:compile
Means 'quartz' has it, exclude the org.slf4j from it.
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.1.7</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
</exclusions>
</dependency>
you may to do it for all the dependencies which contains slf4j. then you can define your desired version of slf4j and use it
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.5</version>
</dependency>
