Case

The project on which I work is built on Eclipse and Ant. I am trying to migrate it to Maven 3.0. I thought to do this within IntelliJ IDEA.
Once the pom.xml was created, I wanted to revert to a configuration based on Eclipse’s .classpath file.
Then IntelliJ IDEA crashes. On starting up again, I get the following error

Cannot load module file 'jonathanModule' Unsupported classpath format eclipse

Quick Fix

For a reason I ignore, Eclipse integration plugin was disabled. To restore Eclipse compatibility, simply do enable Eclipse integration in the plugin preference menu of IntelliJ IDEA.
