Groovy script: Cannot run program [..] filename too long

I have midsized Gradle project with a lot of dependencies. I can run any Gradle task without issue, however, I created a short groovy script in the project that I'd like to be able to run "standalone" (I don't really need, nor want to add, a Gradle task for this).

However, when trying to run the script, I get the infamous CreateProcess error=206, The filename or extension is too long error. I assume this is due to a long classpath because of the large number of dependencies.

Is there a way to work around this error and run a groovy script from the IDE?
