Kill all Gradle Daemons Regardless Version?

Summary

I would like to know how to kill every single gradle daemon and process running on a machine regardless of the version of gradle or the version of the daemon, but the "--kill" or "--stop" command will only stop those processes that match the same version of gradle.

Use case

My CI build box will have several gradle daemons running with different versions (because I'm a good boy that uses the wrapper to execute builds). Occasionally I will find issues with caching or incremental builds, and as a precaution I like to kill the daemons. The same is true for my development boxes, although the conflicts are more often with whichever VCS or IDE I am using.

What I am looking for

1. I'm hoping there is a flag or property I am missing that I could pass to gradle to do this in a simple one line command, but if it's simple enough I would be ok with more.
2. No scripting (looping, if-else etc).
3. Killing all java processes is not acceptable.

Helpful links to the gradle docs

Disabling the Daemon

Stopping an existing Daemon

Under linux you may use pkill:

pkill -f '.*GradleDaemon.*'

Under windows you may use wmic:

WMIC PROCESS where "Name like 'java%' AND CommandLine like '%GradleDaemon%'" Call Terminate

PS. Why "no scripting" when it is probably the easiest solution?
