Next, I indicated where my Main class is. After that, I created a jar file. I click on it and there is the following error: Error: Invalid or corrupt jarfile . How to fix it?

Generally idea generates a Manifest file in the wrong directory. You need to put it in resources

Answer 2, authority 17%

If this error occurs, then you must:

folder

2. Press Build Project (Ctrl + F9)
3. After building press Run (Ctrl + F10)
4. Check if your code is executed correctly (in most cases the error disappears)
