Removing unneeded jars in External library to to deploy on Tomcat server

I'm trying to deploy on Tomcat server and i'm getting the error below even after removing duplicated dependencies ( from maven I click on Clean then Install ).
Error :
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.boot.autoconfigure.security.oauth2.client.OAuth2ClientPropertiesRegistrationAdapter.getBuilderFromIssuerIfPossible(OAuth2ClientPropertiesRegistrationAdapter.java:83)
The following method did not exist:
org.springframework.security.oauth2.client.registration.ClientRegistrations.fromIssuerLocation(Ljava/lang/String;)Lorg/springframework/security/oauth2/client/registration/ClientRegistration$Builder;
The method's class, org.springframework.security.oauth2.client.registration.ClientRegistrations, is available from the following locations:

This error is coming after I build my war file by clicking in Install and copy the file and paste it in webapp folder in Tomcat server then when I start tomcat for deploying , I will get the same error.
This is my POM file , i believe the error is coming from here :

NOTE : I'm using Spring 2.2.2

You have some duplicate dependencies and you're mixing up the old Spring Security OAuth project with the new Spring Security 5 OAuth support. Start by removing all security-related artifacts:
spring-boot-starter-oauth2-client
spring-security-config
spring-security-oauth2
spring-security-oauth2-autoconfigure
spring-security-core
Add:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
This will bring in the correct versions of spring-security-core and spring-security-config, among other dependencies.
Also add:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-oauth2-client</artifactId>
</dependency>

After reading OAuth2 document I resolved this issue by adding "autoconfigure" dependency.
<dependency>
<groupId>org.springframework.security.oauth.boot</groupId>
<artifactId>spring-security-oauth2-autoconfigure</artifactId>
<version>2.4.5</version>
</dependency>

Maven: Compilation error package does not exist. How to add an extra source directory for maven to compile

I am working on Spring boot application with different project structure please find the attached screenshot.
When I go to eclipse and select Run as --> Maven Build with 'clean install' command it gives below error:
**[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /C:/Users/UserName/Downloads/project-api/src/main/java/com/project/api/dto/APIDto.java:[6,35] package com.project.publicapi.dto does not exist**
As classes under src/public/java folder which contains package com.project.publicapi.dto is not compiled.
I have tried to build explicitly and run the project it works. But while building with maven the compilation fails with above mentioned error.
Any suggestion.
Below is the pom file.

Wiremock not availabile to tests despite being in the POM file

I'm trying to spin up a mock HTTP server for my testing, but I cannot get Wiremock to work.
On the mvnrepository.com website, it is suggested as such:
<!-- https://mvnrepository.com/artifact/com.github.tomakehurst/wiremock -->
<dependency>
<groupId>com.github.tomakehurst</groupId>
<artifactId>wiremock</artifactId>
<version>2.9.0</version>
<type>pom</type>
<scope>test</scope>
</dependency>
This however, does not make it available to my test class when trying to import it as such:
import static com.github.tomakehurst.wiremock.client.WireMock.*;
If I remove the <type>pom</type> tag, I can import it but it then fails at runtime because it does not pull in all of the transitive dependencies it needs (such as the Apache Httpclient).
I am not really sure what <type>pom</type> does, as it's not really clear from other explanations, so I don't know how to get past this.
