Problem that clone project cannot be run due to gitignore

I'm using gitignore, and I'm good at push and pull for personal management.

The focus is on my own creation, so I have all the configuration files, so it runs well locally.

However, if I "Clone" this project and download it to an empty folder, it cannot be run anywhere.

It seems as if there is no configuration file necessary for project configuration or server execution.

I am attaching my gitignore.

Is this what gitignore originally intended?

I want to clone a project so that it can run. Do I have to delete gitignore to do that?

p.s If I delete gitignore and clone all projects (including build artifacts) it works fine.

use tool & etc : Intellij, Spring, Tomcat

Solution

Normally, you don't distribute compiled binaries with your git repo. The convention is to either have users compile the code locally, or distribute that code using a package management system like Maven, Ivy, npm, Nuget, pip or gem. This isn't a hard and fast rule however.
