Creating Jar with Intellij 2016 - No main manifest attribute

Question

I am getting no main manifest attribute while running the jar create by Intellij. I extracted the jar and observed that there was another manifest

Answer 1

For Idea Intellij 2020:

1. Remove obfuscation if presents

2. delete/(move somewhere outside the project) META-INF folder in explorer

3. remove artifacts in project structure--> artifacts--> '-'

4. rebuild the project

5. add artifacts again to project structure--> artifacts--> '+'

6. rebuild the project

7. Build-->Build artifacts..

Now the new produced jar should work
