Create Multi-Module Maven Project in IntelliJ IDEA

In this video, you will learn how to develop a multi-module Java Maven project in IntelliJ IDEA. In details, I will show you:
- Create a Maven root project
- Create the 1st module for Shared library project
- Create the 2nd module for Console app project
- Create the 3rd module for Desktop app project
Also, you will learn how to build the whole multi-module Maven project in IntelliJ IDEA using Maven goal mvn install.

Thanks! I've been searching my butt off to get this information. It's a great presentation that shows exactly what to do in IntelliJ. Community version works a bit different in that you have to click a button in the opening screen to make it Maven.😀

Hello, your videos are very cool. I have a question, if I work with Spring Boot, can I create a multi-module project configured to use different versions of Spring Boot? That is, in one module I work with version 2.3.x and in another module with version 2.7. x. I was trying but it didn't work out, I'm sure it can, but the configuration doesn't work out, do you know how I could structure it? Thank you for the answer you can give me. Or you could make a video on that subject, greetings friend.
😄

[@CodeJava]

I think that only works if you do not inherit parent pom in the child modules. So you can specify Spring Boot version for each module individually.

[@magadiflo-dev]

@@CodeJava Thanks for the quick response, I'll try again, greetings friend

Great tutorial. Thank you! I have one question. After performing the "mvn install" that builds the jar files how would you run them as stand-alone applications? I right-click on the .jar file and get the "no main manifest attribute..." error when attempting to run. Do you have the pom.xml code that would build them as executable jars?

[@CodeJava]

you should have spring boot maven build plugin:

org.springframework.boot
spring-boot-maven-plugin

[@DineshkumarPuli]

actually you would need to create a manifest file that points to the class containing the 'public static void main()' method (that starts your app). You can then run the jar using:
java -jar

[@jamilxt]

What would be the process of deploying them?

[@CodeJava]

If you deploy the project on Heroku, parameterize the executable jar file via config var for each module. I'll publish a video about deploying this kind of project on Heroku.

@@CodeJava Thank you. I will be waiting.
