How can I override a typesafe config list value on the command line?
config, java, scala, typesafe
Solution
An alternative syntax is implemented in version 1.0.1 for this:
-Dpoller.datacenters.0=SJC -Dpoller.datacenters.1=IAD
Problem
I have an `application.conf` file with a structure like the following: ``` poller { datacenters = [] } ``` I would like to override `"datacenters"` on the command line. For other configuration keys whose values are simple types (strings, numbers) I can override using `-Dpath.to.config.value=<value>`, and this works fine. However, I can't seem to find a way to do this for lists. In the example above, I tried to set `"datacenters"` to `["SJC", "IAD"]` like so: `-Dpoller.datacenters="['SJC', 'IAD']"`, but I get an exception that the key value is a string, not a list. Is there a way to signal to the typesafe config library that this value is a list?
