Is there a way to use system environment variable in the observed file path of a file event listener? If so, can you provide an example?

Dear ashok,
there is currently no such functionality. We already discussed this possibility, but newer issue was created. So I did it - [https://bug.javlin.eu/browse/CLS-824](https://bug.javlin.eu/browse/CLS-824)

Thanks Jaroslav.
In the interim, do you have a groovy code that can actually read the system env variable, check if the file exists and then delete the file after raising the event?
Thanks,
Ashok

Hi Ashok,
nope, but it should be easy for you to write one 🙂
