IntelliJ IDE | .iml File lost or deleted

Question

Last week I was working on a Java EE project with IntelliJ IDE.

Today: As I started up my IntelliJ 2016.1 it gave me the error:

Error Loading Project

Answer 1

I also removed .iml file by accident. Here is how it was resolved:

1. Closed IntelliJ IDEA
2. Reopened program
3. Selected Import Project -> Create project from existing sources
4. Clicked Next. It created correct project configuration for me.
