Issue with Dependency Injection in Spring Boot Application

I am facing an issue with dependency injection in my Spring Boot Application. While testing Project C, I am encountering a bean not found error for com.project.ProjectA.repository. I have included the necessary packages in @SpringBootApplication(scanBacsePackages), but the bean is still not found. Any insight on resolving this issue?

Parameter 0 of constructor in com.project.ProjectC.AILogController required a bean of type com.project.ProjectA.service.TestingLogService that could not be found.

Consider defining a bean of type ‘projectA.TestingLogService' in your configuration.

@SpringBootApplication(scanBasePackages = {"com.project.projectA”, "com.project.ProjectB”, "com.project.ProjectC”})
public class ProjectCApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProjectCApplication, args);
    }
}

pom.xml

<dependency>
            <groupId>com.project</groupId>
            <artifactId>projectA</artifactId>
            <version>0.0.1</version>
            <scope>system</scope>
            <systemPath>${projectA-systemPath}</systemPath>
        </dependency>


        <dependency>
            <groupId>com.project</groupId>
            <artifactId>projectB</artifactId>
            <version>0.0.1</version>
            <scope>system</scope>
            <systemPath>${projectB-systemPath}</systemPath>
        </dependency>

I'm expecting to merge three spring boot projects together. I've created jar files for com.project.ProjectA and com.project.ProjectB and added it to com.project.ProjectC.

I am able to build the project with out any errors by running the command mvn clean install. However, I'm facing errors when I attempt to run the command mvn spring-boot:run.

To troubleshot this, better to have the stack trace of the exception. But there are couple of things you can check:

1. Does com.project.ProjectA.service.TestingLogService is annotated with @Component or @Service?
2. Is com.project.ProjectA.service.TestingLogService is on the classpath?

Based on your code the first is more probable to be the culprit.
