File Descriptor Leak in DetektExtension.kt

[pablobaxter]

Expected Behavior

All file handlers should be closed upon completion

Observed Behavior

DetektExtension.kt is leaking a file descriptor from https://github.com/detekt/detekt/blob/7a9d960a4dee04d70267a320b1d988004988eed2/detekt-gradle-plugin/src/main/kotlin/io/gitlab/arturbosch/detekt/extensions/DetektExtension.kt#L68C31-L68C45

The following stacktrace was captured after running an evaluation on a local build that uses Detekt several times. Each time, a new file descriptor is opened.

Context

I'm currently looking for plugins that are leaking file descriptors, as I am running into an issue on MacOS where too many file descriptors are being opened, causing Gradle to not complete tasks or builds.
