IntelliJ IDEA run/debug just one file

Question

I have a JAVA project in IntelliJ IDEA that has multiple packages. But some files in my packages have their own main() method and can be run on their own.

However if I do a right click on given file and choose "Debug/Run File.main()" IntelliJ will try to build all the files in the package, no matter if they are included or not.

Is there any way to run just that one file?

Answer 1

You can remove the Make task in your run configuration. But you have to compile the single class manually before launch (Right click or Build -> Compile your class).

Or you could even try to compile the whole project if you need more than a single class. This might work if you have no dependencies to a broken class.

Answer 2

To run a single file in IntelliJ IDEA:

Way 1:

Right-click somewhere in the editing area and select Run 'ClassName.main()'. Say you want to run HelloWorld, you should do the steps below:

1. Right-click somewhere in the editing area
2. select Run 'HelloWorld.main()' from context menu

Way 2:

1. Open the file in editor
2. Ctrl+Shift+F10
