To install JRebel for Eclipse, start by opening Eclipse and navigating to Help > Eclipse Marketplace. In the Marketplace window, search for JRebel, click Install, and confirm the selection. Once the installation process completes, click Finish. You’ll then be prompted to restart Eclipse—go ahead and click Restart Now. After Eclipse reopens, you should see the JRebel welcome page, and upon returning to the Help menu, you’ll notice that the JRebel options are now available.
Alternatively, you can install JRebel using a ZIP archive, which is accessible via a specific URL. Simply paste the URL into your browser, and the archive will download automatically. Once downloaded, return to your IDE and go to Help > Install New Software. In the window that appears, click Add, then select Archive, and locate the ZIP file you just downloaded. Click Open, then Add.
Next, choose the appropriate installation option—typically JRebel and XRebel for Eclipse. Make sure all three available selections are checked. To speed up the installation process, you can optionally uncheck the box labeled Contact all update sites during install to find required software. Click Next, confirm the selected features, and proceed through the next few screens by clicking Next again.
On the license agreement screen, select I accept the terms, then click Finish. If you see a security prompt, select all options and click Trust Selected. After installation, Eclipse will prompt you to restart the IDE. Go ahead and restart to complete the setup.
And that’s it—this ZIP method is a straightforward alternative for installing JRebel on Eclipse, especially useful if you're working offline or outside the Eclipse Marketplace.
