migrating from eclipse to Intellij IDEA

Overview

Switching from Eclipse to IntelliJ IDEA, especially if you've been using Eclipse for a long time, requires understanding some fundamental differences between the two IDEs, including their user interfaces, compilation methods, shortcuts, project configuration and other aspects.

No workspace

The first thing you'll notice when launching IntelliJ IDEA is that it has no workspace concept. This means that you can work with only one project at a time. While in Eclipse you normally have a set of projects that may depend on each other, in IntelliJ IDEA you have a single project that consists of a set of modules.
If you have several unrelated projects, you can open them in separate windows.
If you still want to have several unrelated projects opened in one window, as a workaround you can configure them all in IntelliJ IDEA as modules.
