Use EnvInject Plugin to read your parameters from a file as environment variables in an Inject Environment Variables build step. The glitch is that then you can't override them easily. One solution would be to use it in conjunction with the Conditional BuildStep Plugin. You can then can define a boolean parameter OVERRIDE that would be false by default. You can then run your Inject build step conditionally only when OVERRIDE is false. When you need to override your parameters with values provided by hand (on in a custom call to run the job) specify the override values and set OVERRIDE to true.
