IntelliJ IDEA 15 EAP Adds Indication for Running Configurations

Today we have released a fresh IntelliJ IDEA 15 EAP build, as always with lots of enhancements and new features, one of which is the brand new indicator for the running configurations, that I am going to describe in more detail.

Usually, running several instances of a run configuration makes little sense as every one of them may require individual parameters (e.g. you can’t run several web applications on the same port.), so it’s easier to just define separate configurations with different parameters. To prevent possible conflicts and make it simpler to re-run them, IntelliJ IDEA offers the Single instance only option, that takes care of such situations. Still, until now, you couldn’t tell the actual state of your configuration: whether it’s running or not, there was simply no way of doing that. In IntelliJ IDEA 15 we decided to fix it:


Now every run configuration has a small green indicator that tells you if it’s running. If your run configuration is a Single instance only, IntelliJ IDEA will show you the Restart action instead of the Run action on the toolbar. Otherwise, if there are several running instances of your run configuration, there’ll be a small digit indicator with the number of running instances instead of a small green circle.

If you go to the SettingsAppearance & BehaviourMenus and Toolbars, and add the Stop action to the toolbar, it will let you stop the current running configuration, and if there are more than one running configurations, it will offer you to choose which one you’d like to stop:


We hope these small enhancements will make your life easier, and help you deal with run configurations no matter how many of them you have in your project.

The last but not least is that the Windows installer now uses JRE 1.8 Update 51.

To give the new feature a try, download the latest IntelliJ IDEA 15 EAP build. And don’t forget to share your feedback with us in our EAP discussion forum and issue tracker.

    Everything suddenly got massive text/icons using Linux with this update. Some HiDPI errors? Previous EAP was perfect, what did you do? 😛

    Would be very cool to see gradle support improved…

    what do you mean by single instance

    how does one do redeploy instead of restart?

    • Andrey Cheptsov says:

      Single instance only is the checkbox in the Run configuration dialog you an enable. When you press restart it redeploys. If you press Update it may ask you how you would like to have it done: restart, redeploy, reload classes/files.

      • Mateus Viccari says:

        But even if you set “On update action” to “Redeploy”, it still asks you to “Stop and rerun” (restart server) because it is a single instance run configuration.
