Here are 2 examples with maven project, step by step:

Method 1: Build jar with maven and pom.xml

1. File, new, project, maven
2. create a package , create a java program inside that package

3. at pom.xml, add maven-jar-plugin.

       
           
           org.apache.maven.plugins
           maven-jar-plugin
           3.1.0
           
               
                   
                       true
                       lib/
                       somePackage.sample
                   
               
           
       
   

screen capture: 4. open maven project box by click on the search icon and type maven,

5. click on clean, then click on install

6. your jar file will show up inside the target folder

7. test your jar using java -jar

Method 2: Build jar with maven without pom.xml change

1. File, new, project, maven
2. create a package , create a java program inside that package (same as above)
3. File -> Project Structure -> Project Settings -> Artifacts -> Click green plus sign -> Jar -> From modules with dependencies

Very important!

The MANIFEST.MF needs to be in your resources folder and the Main.Class needs to refer to {package}-{class-name-that-contains-main-class}

4. then click build on menu , build artifacts, build

5. find the jar in the out folder

6. run it :)
