Kia ora,
I need to deploy the ORS Java source code to a .jar file alongside my larger project code. In doing so, I need to specify the ORS config file in use. To date (i.e. in IntelliJ), I have done so by specifying an environment variable:
ORS_CONFIG=custom-ors-config.json
In which I radically increase the search limits for isochrones, etc. Now that I am deploying to a .jar, I need to specify the environment variable from the terminal. My current method is to append the following to my java initialisation call:
-DORS_CONFIG=custom-ors-config.json
However, the .jar cannot find the config file (unmoved since compilation), despite the config file (and the default config files) being present in the jar, and I get the following exception:
Exception in thread "main" java.lang.ExceptionInInitializerError

Is there a way I can specify a precise path for a config file instead of merely a name that ORS is expected to find? e.g.
-DORS_CONFIG=/Users/mak/folderA/folderB/custom-ors-config.json
I realise this is a pretty simple question, but my hours of trial and error are proving fruitless.
EDIT: I have hacked this, passing the location of a custom config file to my main class, which I then pass to AppConfig directly as a static parameter. Not ideal, but it works.
Additionally, I need to access the resources folder within the jar, but the LocalizationManager class is making this exceptionally difficult. Any recommendations, there?
Ngā mihi,
Mak
