Practicing to upload Java project from IntelliJ using git from scratch

This is my first project where I am trying to create Java application on Intellij and pushing on Github

On Intellij, I created New -> project -> Maven -> gave groupId,artifactId,version and then folder path
then created package inside src/main/java -> com.example and wrote Hello-world.java and Calculator.java files
Then for testing I created inside /src/test/java - >com.test and wrote CalculatorTest.java file
I just used @Test annotation and then alt+enter asked me to choose junit-4 and then done

Now challenge was how to upload this on github:

Enabled VCS inside intellij
$ git init -> it created .git file
There were some folders like .idea/ and DS_Store(mac property) and target/ which I don't want to upload so kept them inside .gitignore file

4.$ git status -> it now show me required folders which I need to add on my remore repository

I went to github, created new repository which is current one and WITHOUT readme.md , else we won't be able to push from local to remote and has to first pull and local goes out of sync(I faced it :( )

6.$ git remote add origin

$ git push origin master

Making it executable jar, whatever artifactId and version we passed, same name jar is created by default if we dont add in pom.xml

  $ mvn clean 
  $ mvn compile
  $ mvn package

To verify if jar is working

    $ jar tf target/Example-1.1-SNAPSHOT.jar
    $ java -jar target/Example-1.1-SNAPSHOT.jar

This threw ERROR: no main manifest attribute, in target/Example-1.1-SNAPSHOT.jar

The -jar option only works if the JAR file is an executable JAR file, which means it must have a manifest file with a Main-Class attribute in it.

Hence, I added this property inside pom.xml and Boom!!!!

                <build>
                    <configuration>
                      <archive>
                        <manifest>
                            <mainClass>com.example.Demo1</mainClass>
                        </manifest>
                    </archive>
                    </configuration>
                <build>
