IntelliJ IDEA is a favorite IDE among developers working with Java, Kotlin, JavaScript, and more, thanks to its powerful features and intuitive interface. However, even great tools have some quirks; one issue users often encounter is IntelliJ IDEA’s frustrating tendency to re-import the entire project whenever you switch between windows or applications. If you’ve experienced this issue, you’ll know how disruptive it can be to your workflow.
Constant re-imports don’t just waste precious minutes—they break your train of thought. Imagine being deep into debugging or coding, then briefly switching to your browser or documentation. As soon as you return, IntelliJ IDEA starts scanning and reloading your entire project again, grinding your productivity to a halt.
To fix this persistent annoyance, it’s important to first understand why IntelliJ IDEA behaves this way, then follow a clear step-by-step process to eliminate it for good.
Understanding the IntelliJ IDEA Project Re-Import Problem
When IntelliJ IDEA switches back from another application window, it can detect file or directory changes. Even subtle interactions with version control software like Git or file-syncing tools such as Dropbox or Google Drive can trigger the IDE into believing the project’s files have changed, causing a complete re-scan.
Besides file system checks, IntelliJ IDEA performs automatic synchronization to ensure that your project workspace accurately reflects the latest file system state. Although useful in theory, the reality is frequent switching between applications can cause excessive scanning, even if changes were minimal or nonexistent.
The result? Constant interruptions that negatively impact productivity. Developers find themselves waiting unnecessarily, significantly reducing their coding efficiency and overall user experience.
Investigating the Best Available Solutions
The good news is that several practical solutions exist that users have shared and refined through experience. Exploring IntelliJ IDEA’s built-in settings, community forums like Stack Overflow, and official JetBrains documentation often yields viable fixes.
Some users, frustrated by constant re-imports, even consider alternative IDEs like Visual Studio Code or Eclipse for comparison. But don’t worry—before jumping ship, there’s plenty you can try within IntelliJ IDEA itself.
Step-by-Step Guide to Fix IntelliJ IDEA Re-Importing Issue
1. Turn Off Automatic Project Synchronization
The quickest fix involves adjusting IntelliJ IDEA’s automatic synchronization settings. By disabling the automatic synchronization, you prevent the IDE from initiating constant re-imports. Here’s how:
- Go to File → Settings → Appearance & Behavior → System Settings.
- Uncheck the box labeled “Synchronize files on frame activation” and “Save files on frame deactivation”.
- Click Apply, then OK.
Adjusting these settings stops IntelliJ IDEA from rescanning instantly when you switch windows, significantly improving your workflow.
2. Adjust Window Switching Behavior in Your OS
Sometimes, operating system settings contribute to the IDE’s aggressive behavior. Certain window managers aggressively notify IDEs about possible file modifications. Double-check your OS file indexing settings, antivirus software scans, or background-syncing services like Dropbox and Google Drive.
Preventing frequent syncing or temporarily disabling non-essential background processes can help minimize unintended file system alerts reaching IntelliJ IDEA.
3. Utilize IntelliJ IDEA Plugins for Enhanced Stability
Many third-party plugins can increase IDE stability and performance, including preventing excessive rescanning. Explore IntelliJ IDEA’s plugins marketplace within the IDE—accessible via File → Settings → Plugins—for tools that enhance file management or project synchronization.
Plugins such as Save Actions help manage automatic saving explicitly, giving you more control over the IDE’s behavior.
4. Follow Recommended Best Practices
Good habits also help eliminate needless rescans:
- Keep version control tools’ interactions minimal during coding sessions.
- Close unneeded background apps to reduce inter-application file triggers.
- Run indexing-intensive operations during breaks rather than active coding periods.
Adopting these basic practices can dramatically enhance your overall experience while using IntelliJ IDEA.
Testing and Troubleshooting After Applying Fixes
After making these changes, it’s important to test whether they truly fix the issue. Switch windows numerous times and monitor IntelliJ IDEA’s response closely:
- Open multiple apps alongside IntelliJ IDEA (e.g., browser, file explorer, terminal).
- Rapidly switch between IntelliJ IDEA and these apps to check whether automatic re-imports still occur.
- If problems persist, revisit settings and consider checking with JetBrains Support or searching community forums.
Troubleshooting is an iterative process, so patient experimentation is key to achieving optimal performance.
What Users are Saying: Feedback and Tips
After implementing the above fixes myself and speaking with other IntelliJ IDEA users, the improvement in daily productivity is remarkable. Users generally report positive results after disabling automatic file synchronization:
- “Disabling the synchronization setting immediately enhanced my productivity—I haven’t had unprompted re-importing since!” (Developer, Stack Overflow)
- “Adjusting window-switch settings and turning off syncing dramatically sped up my workflow.” (Comment from JetBrains community forums)
Extra tip: Regularly clear IDE caches (File → Invalidate Caches/Restart) if IntelliJ IDEA shows persistent weird behavior. It often resolves many subtle problems instantly.
Optimize IntelliJ IDEA for a Smooth Development Experience
By following the simple guidelines outlined above, you’ll effectively eliminate IntelliJ IDEA’s recurring re-importing problem when switching windows. Taking these proactive steps not only improves your IDE responsiveness but also helps maintain your coding flow.
If you’re working with JavaScript specifically, this guide complements essential JavaScript best practices and tools, boosting your overall development productivity across languages.
Remember, IntelliJ IDEA offers extensive customization possibilities—adapting its settings to your specific workflow pays off with smoother coding sessions and fewer frustrations.
