Spring Camel: Process finished with exit code 0

Question

I am trying to integrate camel into an existing spring project that uses an embedded tomcat instance to run locally. The spring project works before I add any camel dependencies, however, after 4 camel dependencies are added, I get the message "Process finished with exit code 0". I am building the application with maven and running it inside an embedded tomcat instance (mvn clean install -Pembedded (see profile below)).

I am not a Camel newbie, but I still cant figure out how the dependencies below are causing my spring process to finish running (it seems like spring sees nothing to execute after the camel dependencies are added). How can I keep the existing spring application working and still have the new camel dependencies?

Here are the new dependencies:

    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-core</artifactId>
        <version>${org.apache.camel.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-aws</artifactId>
        <version>2.19.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-test</artifactId>
        <version>${org.apache.camel.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-http4</artifactId>
        <version>${org.apache.camel.version}</version>
    </dependency>

Is there any error messages in log files? Try removing scope for spring-boot-starter-tomcat — nayakam

Remove the provided scope for spring-boot-starter-tomcat then it become default scope compile. In embedded tomcat environment, You should set default scope compile and if you wish to deploy the war to any other standalone tomcat. This dependency can be marked as provided.
