How to import Eclipse projects to IntelliJ IDEA?

In IntelliJ IDEA 11 you should use File | New Project, Import project from external model.

Also check that Eclipse Interoperability plug-in is enabled in Settings | Plugins.

In IntelliJ IDEA 14.1.4 you can import a project with the following existing sources:

• Eclipse project (.project) or classpath (.classpath) file
• Maven project file (pom.xml)
• Bnd/Bndtools workspace (workspace/cnf)
• Flash Builder project file (.project, *.fxp, *.fxpl)
• Gradle build script (*.gradle)

Go to File → New → Project from Existing Sources… and a dialog will open that allows you to open one of the supported files or directories.

In IntelliJ IDEA 11.1 you can find the import option in the New Project dialog. You can find it at File | New Project.
