How to configure multi module spring application - maven

Question

Here is my project structure :
I have two spring-boot modules. In auth module I implement spring security. And I have Auth controller that allows us to sign up and sign in(returns jwt token).
In account-management module I want to get user profile and I should use auth module. I should have different databases.
Here is my parent pom :
<groupId>com.social.network</groupId>
<artifactId>social-network</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<modules>
<module>social-network-auth</module>
<module>social-network-account-management</module>
</modules>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
Here is auth module's pom :
<groupId>com.social.network.auth</groupId>
<artifactId>social-network-auth</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>social-network-auth</name>

</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
And here is my account-management's pom
<groupId>com.social.network.account.management</groupId>
<artifactId>social-network-account-management</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>social-network-account-management</name>

</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>com.social.network.auth</groupId>
<artifactId>social-network-auth</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
I want to run all my modules.
But build fails. I am getting Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project egs-social-network: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]

Answer 1

First of all you should understand that two different application could not be running on the same port. So you thought in the right way, but the main goal is to separate logical parts to different modules, my congatulations, you have already done it. So now, just make the right dependency chain. (child -> parent!) And also the child module could not be a spring boot application. It could be some kind of additional sets of classes or library for your main module. And please read the answer How to make one module depend on another module artifact?. You can have multiply controllers in one application, but with different mappings, you don't need for this purposes two different applications.
By the way, first off all please run mvn package and install =)

Answer 2

You have to call
mvn spring-boot:run
in each module to run the applications.
You find the goal under "Plugins".
But as you are using IntelliJ there is a Spring Boot Run Dashboard where you can run all applications.
