1. Introduction
Nowadays, working with multiple projects is very common. Opening multiple instances of the IDE for each project isn’t very convenient and also consumes a lot of system resources.
In this tutorial, we’ll learn how to open multiple projects under the same window in IntelliJ. This works on both the Community Edition and the Ultimate Edition of IntelliJ.
2. Opening Multiple Projects in IntelliJ
IntelliJ shows the project structure of a current workspace in its Project Structure menu. If we compare it with Eclipse IDE in terms of terminology, IntelliJ refers to the main workspace as a Project and the different applications/projects as Modules.
There are two ways to locate Project Structure:
- Via menu navigation – Navigating to File -> Project Structure
- Via keyboard shortcut – For Windows, we press Ctrl + Alt + Shift + S and for OS X, we press ⌘Cmd + ;
As a result, it opens the Project Structure dialog.
To add a new project to the same workspace, we follow the path Project Settings -> Modules. Then, we’ll see a popup dialog appear that looks similar to this:
Under the Modules section in the upper left corner, we have a “+” button that allows us to create a new module or import an existing one.
When importing the module, we can select either the build.gradle file or the pom.xml file of a project:
Based on the file, it adds the module in the same workspace, identifies the build tool, autoconfigures the required things, and builds the project.
After the module is imported, we have an option to change the JDK version from the Project Structure menu, if it requires a different version:
3. Conclusion
In this article, we learned how to add multiple projects in the same IntelliJ workspace window. We also highlighted that we can directly select the build file of the application to import the module and allow automatic configurations. We can also change the JDK version for a newly imported project if it’s different from the default project settings.
