Spring Boot mvn Project doesn't run after adding dependencies

I developed simple functionalities in a small Spring Boot Project. Now I want to move these functionalities into an older existing project that I sadly did not develop by myself and did not follow the advices on how to build the pom by specifying a parent.
I am not that experienced in Spring Boot to be able to resolve the errors when I try to add new new dependencies into the old project.
The pom.xml of the newer working project:
To summarize I have the starter-parent and dependencies for data-jpa, web, mysql and lombok.

spring-aot-maven-plugin failing on mvn clean package

I have a project early created and when trying to run mvn clean package command, or any other mvn command to build my .jar, the spring AOT plugin is throwing the following error:
[INFO]
[INFO] --- spring-aot-maven-plugin:0.9.0:test-generate (test-generate) # server ---
[ERROR] org.springframework.aot.CodeGenerationException: Could not generate spring.factories source code
While researching, I've followed the documentation and I could not see what's going on on my project that could be causing this error. I even tried to change spring-aot-maven-plugin versions, but it keeps returning the same problem.
If someone knows how to solve this issue, it would be a good help.
Thanks.

This works for me:
Remove the spring-boot-devtools dependency from the general dependencies section
Create a profile like
<profile>
<id>local</id>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
</dependencies>
</profile>
Use the local-profile for running only: mvn -Plocal spring-boot:run or make it the default by adding the following to the profile section
<activation>
<activeByDefault>true</activeByDefault>
</activation>

Spotbugs mvn plugin missing classes needed for analysis

I'm using a GitLab CI/CD Pipeline that uses the spotbugs plugin for Maven; when I try to run
mvn compile spotbugs:check
I get the following error:
[INFO] Fork Value is true
[java] The following classes needed for analysis were missing:
[java] org.junit.jupiter.api.Assertions
The previous command works on my local machine, but fails on the GitLab runner. I suppose this may be a configuration problem (ie: something wrong on my pom.xml file) but I am not quite sure how to fix it.

Maven - How to exclude dependencies from generated JAR

I have 3 projects that looks like this:
The problem is that the common DB code has a converter class, and I am getting the below error while running the Business logic.
Caused by: org.hibernate.AssertionFailure: AttributeConverter class [class com.td.sba.iep.jpa.converters.ModeltoDBAttributeConverter] registered multiple times
What I did:
I tried to exclude the dependencies while packaging the Utility classes using the below code in pom.xml.
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<!-- Fools the plugin into creating the code only jar instead of the runnable one -->
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>exec</classifier>
</configuration>
</execution>
</executions>
</plugin>
But when I include the exec jar created into the Business logic, it shows that the utility classes are not found.
WHAT I NEED:
How do I fix the 'org.hibernate.AssertionFailure'?
Should I exclude the dependencies while creating the jar from utility classes? How do I do it?
Incase it matters, I am using Eclipse.

Have you tried to use <exclusions> element on this project dependencies? Like:
Business Logic Project pom.xml file:
<dependency>
<groupId>com.utility.project</groupId>
<artifactId>UtilityProject</artifactId>
<version>1.0.0</version>
<exclusions>
<exclusion>
<groupId>group.id.jar.you.want.to.exclude</groupId>
<artifactId>artifact.id.jar.you.want.to.exclude</artifactId>
</exclusion>
</exclusions>
</dependency>
UPDATE
Since you already have CommonDB dependencies on your UtilityProject pom, remove this CommonDB dependency from your business logic pom. This error is because you have 2 classes (same class) being registered with same name. If you already have CommonDB dependency on UtilityProject and you use this UtilityProject as dependency on Business, you don't need to import it twice.

I am able to run it in eclipse. but some ho when I generate jar, I get error 'Could not find or load main class com.faro.engine.MainAppLoader
here is my pom file'.
any ideas please?
thanks in advance :)

Some things you could check:
Is MainAppLoader under com.faro.engine package?
Is MainAppLoader annotated with #SpringBootApplication?
The spring-boot-maven-plugin already assembles your application as a jar with dependencies. Do you really need the maven-assembly-plugin?
As a sanity check, you could try replacing your plugin declaration with.
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
