my main root pom and also web module pom and model module pom is there so How to make single war file instead of multiple war file of each module.Or any ather way to make war file from these jars generated and war file contain application.properties and WEB-INF and META-INF folder with lib folder

so how to make only single war file instead of multiple war files of each module
Your multi-module project structure and POM should be like this
Parent - pom.xml -> Packaging pom
Module1 - pom.xml -> Packaging jar
Module2 - pom.xml -> Packaging jar
Web - pom.xml -> Packaging war

In your case you added packaging as a jar in web module(pom.xml), change web module packaging as a war.
Old Code
<packaging>jar</packaging>
New code
<packaging>war</packaging>
Please follow the below spring boot maven multi module project guidelines for more details

I have developed a multi-module project with Java spring boot on IntelliJ.
This is runnable in the IDE without any problem via 'run Application' where 'Application' is my SpringBootApplication and located in a submodule of the parent module.
Now I want to run this system on a server and I am unable to get it running. I tried
mvn spring-boot:run
and I get following error:
Error: Could not find or load main class com.example.application.Application
Caused by: java.lang.ClassNotFoundException: com.example.application.Application
I also tried other commands like
mvn clean package
where I get errors saying that packages from the 'shared_model' (succesfully compiled - because no dependencies of other modules) do not exist (although they exist), while trying to compile 'aggregate'-package (depending on 'shared_model'), e.g.:
[ERROR] /.../aggregates/src/main/java/com/example/aggregates/.../.java:[3,52] package com.example.shared_model.... does not exist
[ERROR] /.../aggregates/src/main/java/com/example/aggregates/.../.java:[13,12] cannot find symbol
The file structure looks like this:
main
├── adapters-input
├── adapters-output
├── aggregates
├── application
├── application-services
└── shared_model
Where every package has its own pom-file.
The pom of the parent module looks as follows:

I tried a lot of things and became a little desperate. It seems like there is an issue with seeing sibling-modules and child-modules, but I don't see why. Also, I don't understand why it is working smoothly from when ran from IntelliJ.
I greatly appreciate any help. Thanks!
I'm developing spring-boot application. After building the project, the size of jar file becomes 40 MB which 99% of it is dependencies that exits in BOOT-INF\lib.
I'd like to move the lib folder outside of generated jar file and upload it only once to server and upload just the project jar file since then in order to rapid deployment.
How is it possible to do that?

I am implementing a Microservice library, which can be used by other developers to create microservices without taking the pain of implementing internal features like health, metrics, Kafka communication etc.
I am planning to create a multi-module maven project and I will install the library jar separately and this jar will be added as dependency in the application pom.xml.
This is the folder structure I am using:

Here are my questions:
1. Am I implementing the right directory structure?
2. What is the purpose of pom.xml inside MicroServiceApplication?
3. Where should I specify spring-boot-starter-parent artifact - In library or application pom.xml?
Am I implementing the right directory structure?
This is totally up to your project module structure. But, you need one pom.xml at project root folder.
What is the purpose of pom.xml inside MicroServiceApplication?
You need pom.xml to download required jar from maven central repository.
Where should I specify spring-boot-starter-parent artifact - In library or application pom.xml?
As far as I understood, they are microservice and they might be running independent. right ? Then, you should include spring-boot-starter-parent in both.
I have two profiles in my pom.xml. A default and another is used to build swagger client library. I import this library in my another maven project. The problem is that it uses all the dependencies from the first project, even those that are mentioned in default profile. What is the best way to solve the problem? Is it possible to put only one profile in pom file when generating jar? Or is it possible to choose a profile when importing a dependency?
You need something like this
1) a parent that holds it all together

You missed the <dependencies> element (all <dependency> elements should be inside a single <dependencies> node):
