How to Open Multiple Projects in IntelliJ: A Simple Guide

Have you ever wondered how to open multiple projects in IntelliJ? Although IntelliJ does not support workspaces, there are ways to work with multiple projects in the same window. In this article, I’ll show you how you can optimize your workflow in IntelliJ.

Why Doesn’t IntelliJ Support Workspaces?

Unlike other development environments like Eclipse, IntelliJ IDEA does not use the concept of workspaces to manage projects. In Eclipse, a workspace is essentially a place where all your projects are stored, allowing you to open and work on multiple projects simultaneously within the same instance of Eclipse.

On the other hand, IntelliJ IDEA takes a different approach. Instead of having a workspace that contains several projects, IntelliJ IDEA considers everything as a single project, which can contain several modules. In this context, a module is like a project in Eclipse. Each module can have its own set of dependencies, its own build and run configuration, etc.

The approach of IntelliJ IDEA has several advantages. For example, it facilitates the management of dependencies between modules and allows greater flexibility in the configuration of each module. However, it also means that you cannot simply open multiple projects in the same IntelliJ IDEA window in the same way you would in Eclipse.

But don’t worry, there’s an alternative solution that will allow you to work with multiple “projects” in IntelliJ IDEA, which we’ll explain in the next section.

Opening Multiple Projects in IntelliJ

Don’t worry, doing this in what has become the standard IDE for Java development today is also super simple.

You will only need to change your mindset and start thinking in modules, like what you probably called projects in Eclipse.

To add a new project in the same window of your IntelliJ, follow these steps:

  1. Go to File
  2. Select New
  3. Choose Modules from external source
  4. Select the project folder
  5. And that’s it! You will have all the projects you have in that folder open in your IntelliJ instance in a very similar way to how Eclipse does with its workspaces.

Opening multiple projects in IntelliJ may seem a bit strange at first, especially if you’re used to working with Eclipse’s workspaces. But as you can see, it’s quite simple. If you have any questions or run into any problems, don’t hesitate to leave a comment. I’m here to help you!
