JRebel is a productivity tool that allows developers to reload code changes instantly. It skips the rebuild, restart, and redeploy cycle common in Java development. JRebel enables developers to get more done in the same amount of time and stay in the flow while coding. JRebel supports a majority of real-world enterprise java stacks and is easy to install into existing development environments.

Hi vsp99h, thanks for the feedback! We have identified and fixed the Debugger issue on Intellij 16 EAP - please upgrade your JRebel plugin for Intellij and give it a try.

With IDEA 16 the plugin brokes IDE focus on Java breakpoint when inactive Java Debug tab.

Hi! @Anonymous: If you are an owner of the old perpetual license then you certainly are an early supporter. We discontinued giving out these licenses more than 5 years ago and now the policy related to them has indeed changed, as the product itself has changed significantly. You can continue using JRebel 5.x forever as is. About JRebel 6 and all future versions, can you please contact me personally at sander at zeroturnaround com, lets see if we can figure out a suitable solution :) -- Sander Sõnajalg JRebel product manager

Since plugin version 6.0.0 it never stops complaining about activating JRebel. But I want to use the JRebel 5 agent since that is the last version that supports my old license key. In a related note: I got my key in the early JRebel versions (when it was still called JavaRebel). Even though they claimed back then that my license would work for all future upgrades, they stopped doing so. Since they started screwing over their early supporters, I will NEVER use JRebel 6 or higher. I will probably switch to Spring Loaded at some point.

Please send more details on your proxy configuration to

This bug (fixed with 5.6.0) seems to be back in the latest version with Idea 14: Problem when plugin failed to pass IDEA proxy settings to JRebel. Proxy settings from Idea doesn't have an effect. Always got HTTP error 407. Same proxy settings and license server url in eclipse working just fine.
2014-11-10 11:43:38
Yes, but the update failed, had to uninstall an reinstall the plugin to get it to work.
2014-11-07 10:22:42
The latest version of the plugin works with IntelliJ 14. Update the plugin if you haven't yet.
2014-11-07 10:14:02
When is support for Intellij 14 coming?
2014-09-24 13:47:16
Plugin works, but the licence seat is acquired as soon as IntelliJ starts, not when the JRebel work session starts. This is really annoying in a dev team as we are forced to buy a floating licence for each developper, when at most 70% of them is working at the same time
2014-06-20 14:28:14
My license is activated, but plugin keeps asking for the activation all over again

zhouji IDEA 13 is not final yet. We will be working on version 13 support in some time.
