Is it possible to run multiple applications in IntelliJ with just one press of a button?

Is there a way to run multiple applications with just one press of a button?

Say, I have AppA, AppB, and AppC (they are all in java). Is there a way that they could run all 3 in some order with just one button press?

It's kinda tedious hitting the "run" button for like 10 applications. I'm assuming a script or maybe a plugin?

I think this has been possible since version 15. You simply create a Run/Debug Configuration of type 'Compound', and select the configurations you want to run, so:

0. Ensure you have previously set up run configurations for the various applications (or other run configurations) that you want to run.
1. Click on the 'Run' menu
2. Click 'Edit Configurations'
3. Click the green '+' icon (top-left of the window)
4. Click 'Compound'
5. In the right-hand pane, enter a meaningful name for your group, then click the green '+' icon (the one in the right-hand pane, not the top-left of the window)
6. Select one of the run configurations
7. Repeat 5 and 6 for all the configurations you want to run in a single click
8. Hit OK
9. Select your newly-created compound configuration in the drop-down in the menu bar
10. Hit the run button (note that you don't appear to be able start all the applications in debug mode, if you want to do that, you'll need to do so individually)
11. Watch all your applications start, one-by-one. Revel in your newly discovered free time

2 drawbacks:

1. As CashIsClay points out below, you can't explicitly change the order that your configurations run in; they run in alphabetical order. I'm not sure that this is a big restriction though, I'd want my applications to be able to start in any order for resilience in production environments. Of course, a non-terrible workaround would be to name your run configurations something like: '1. Foo'; '2. Bar', if it's essential for Foo to run before Bar starts.
2. You can only start in 'run' mode, not 'debug'.

Other answers have mentioned the Multirun plugin, which may offer more functionality than IntelliJ's native options. I haven't used it, but it might be worth looking at.

There seems to be a Multirun plugin for IDEA:

You can do this. Go to Run -> Edit Configurations....

Older IntelliJ versions:
Check Allow parallel run, then you can start multiple main classes.

IntelliJ 2020+:
Select Modify options. A popup appears. Enable Allow multiple instances.

You can agroup the projects, go to "Edit Configurations..."

The following screen will open, under "Application" configure your settings

Once you create a "Compound"

And put "Compound" your settings

Done, just run the "Compound"

There is no such feature yet, please vote:

• IDEA-94341 Launch Multiple "Run/Debug Configurations" At Once

Edit run configuration, check the allow run parallel checkbox.

Select the Written program(java/Scala) --> right click --> Edit --> Select Allow parallel runs check boxenter image description here
