How to Create Nested Packages in IntelliJ IDEA for Java Projects

If you're a Java developer working in IntelliJ IDEA, you might have encountered the frustration of trying to create nested packages within your project. You expect a specific structure, but the IDE seems to automatically flatten your package hierarchy, leading to confusion and wasted time. In this guide, we’ll explore how to resolve this issue and successfully create and manage nested packages in IntelliJ IDEA.

The Problem: Flattened Packages

When you attempt to create a package structure like this:

Instead, you might end up with the following output in your IntelliJ project:

This is not what you intended, and it can make your project organization messy and difficult to navigate. The underlying issue seems to be the way IntelliJ IDEA is configured to display and manage packages.

The Solution: Adjusting Your Settings

Fortunately, there’s a straightforward solution to this problem. By changing a couple of settings in IntelliJ IDEA, you'll be able to create nested packages as you originally intended.

Here’s how to do it:

Open the Project View: On the left side of your IntelliJ window, find the Project tab which displays your project's structure.

Access Settings: Look for an icon resembling a gear or an ellipsis (three dots). This will open the options menu for the Project view.

Turn Off Flatten Packages: In the options menu, locate the Flatten Packages setting. Make sure to turn this option off. When this is enabled, IntelliJ condenses your package structure, causing unexpected behaviors like the flat display you experienced.

Uncheck Compact Middle Packages: Just below the Flatten Packages option, you may see a setting for Compact Middle Packages. Uncheck this option as well. This setting can further complicate how packages are displayed, contributing to the flattening problem.

Visual Summary

To summarize these actions visually, follow these steps:

Settings Menu: Click on the settings icon in the Project tab.

Disable Flatten Packages: Uncheck Flatten Packages.

Disable Compact Middle Packages: Uncheck Compact Middle Packages.

Conclusion

By adjusting these settings in IntelliJ IDEA, you can regain control of your package structure for your Java projects. You’ll be able to create nested packages as intended, keeping your project organization neat and purposeful.

Don’t hesitate to explore these settings whenever you feel your project structure isn't reflecting your expectations. Happy coding!
