mvn install or package fails because unable to find symbols from another package in workspace

Question

I have a spring boot project Proj-Main and another project which contains entity classes called Proj-Entities. Both of these are present locally. I have added the latter as a dependency of the first. It works perfectly in my IDE (in my case STS) however when i try to create a jar to deploy to server using mvn package or even mvn install for Proj-Main, it fails to find classes which are present inside Proj-Entities. I have checked my .m2 directory and I am able to find the jar for Proj-Entities there. I have tried standard clean and rebuild techniques but it just doesn't seem to work.

This is how i am adding dependency:

    <dependency>
        <groupId>com.proj</groupId>
        <artifactId>Proj-Entities</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>

My build task looks like this:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Answer 1

Solved this by adding the following build goals to the Proj-Entities pom.

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
