That said, thanks to JetBrains, I have now access to IntelliJ IDEA and I already started migrating my projects from Eclipse. I have been using IntelliJ all day and so far I love it (especially because I managed to make it run on Mustang and see subpixel antialiasing almost everywhere:).

This option imports the selected project to IntelliJ IDEA as is (opens it). If you want to set custom settings while importing the project (for example, select another JDK or choose the libraries that you want to import), refer to Import an Eclipse project.

  1. Launch IntelliJ IDEA.

    If the Welcome screen opens, click Open.

    Otherwise, from the main menu, select File Open.

  2. In the dialog that opens, select the directory in which your sources, libraries, and other assets are located and click Open.

  3. When you're importing or cloning the project for the first time, IntelliJ IDEA analyzes it. If the IDE detects more than one configuration (for example, Eclipse and Gradle), it prompts you to select which configuration you want to use.

    Select the necessary configuration and click OK. The IDE pre-configures the project according to your choice.

  4. If you have been working with another project, select whether you want to open the new project in a new dialog or in the current one.
