spring-boot packaged as jar throws error - maven

Question

I am writing a code using spring-boot (FatJarBuilder). Below is the snippet of the code
#SpringBootApplication
public class ConsumerBuilder extends FatJarRouter {
#Override
public void configure() {
...
}
}
In actual code, i am subscribing kafka (using camel/avro/snappy) and reading the messages.
I am using Maven. When I run using the below command my app is working
"mvn spring-boot:run"
but if I package this as a JAR and run it, I am seeing the below exception

I also added the below entry in properties file
spring.main.sources= com.tgt.feed.ConsumerBuilder

Answer 1

There was this suggestion a year ago . Look at it if it helps
If you're not dropping jars into the WEB-INF/lib folder in your
project, anything you need at runtime (in addition to compile time)
needs to be marked as such in the "Deployment Assembly" property page
for the project.

Answer 2

The Camel Avro component contains a dependency to the servlet api 2.5, Spring Boot needs a 3.1 api version. You have to remove it :
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-avro</artifactId>
<exclusions>
<exclusion> <!-- declare the exclusion here -->
<groupId>org.mortbay.jetty</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
