Setting environment variables for an entire project

Question

In Eclipse, it is possible to set environment variables using "run configurations", but this works only for a specific main program.

I have many different main programs in the same project, and I want to set the same environment variables in all of them. What is the easiest way to do this?

Answer 1

What I usually do for a global environment variable is usually set it at the OS level. I do not know if there is a way in Eclipse to set global environment variables.

Answer 2

You can create and set variables globally in Eclipse via the String Substitution form. The form is found via Preferences->Run/Debug->String Substitution.

Variables declared in the form can be used by referencing them with ${variable_name}.
