Creating .jar files for Spring project

Introduction

With jar files you can create multiple instances of your maven project.

Clean

First you need to clean up your target files so go to the right top corner and click on Maven.

There you will be able to see the option to clean under "Project Name" > LifeCycle > clean

That will go ahead and delete all your target files.

Build

Now in the same directory under Maven, select “install” which will take care of all the aforementioned options (clean, validate, compile, test, package, verify).

This of course includes all the testing that needs to be done and the jar file will be created under target > projectName-version-SNAPSHOT.jar

Execute

In order to run the created jar files, input into your terminal:

java -jar target/demo-0.0.1-SNAPSHOT.jar

Or if you want to run it on another port

java -jar target/demo-0.0.1-SNAPSHOT.jar --server.port=8081
