How can I pass command line parameters to Gradle run configuration?

I have a simple Gradle run configuration and I want to add command line parameters to the task that is called.
Something like (when run from the command line):

gradle run -Pabc=def
I tried adding

-Pabc=def
to VM options.
And running

run -Pabc=def
in Tasks.

None of them works.
What is the correct way to do that via Intellij Idea configuration?
