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

My mvn project was not also loading correctly in IntelliJ IDEA after I removed .iml file. I fixed it this way:

1. Closed IntelliJ IDEA
2. Deleted .idea dir which was in my project dir.
3. I reopened IntelliJ IDEA and .idea dir and also .iml was after a while automatically recreated by IntelliJ.

Fixed for me.
