In my jenkins configuration for "Global properties", I have a property TEST_WORKSPACE defined as ${WORKSPACE}.

Then in my jenkins job I have "prepare an environment for the run" defined to a file which does not set TEST_WORKSPACE or WORKSPACE.

But, when I run the job, TEST_WORKSPACE is not defined in console, I get this:

[EnvInject] - Loading node environment variables.
[EnvInject] - Preparing an environment for the build.
[EnvInject] - Keeping Jenkins system variables.
[EnvInject] - Keeping Jenkins build variables.
[EnvInject] - Adding build parameters as variables.
[EnvInject] - Injecting as environment variables the properties file path '/home/jims/global.prop'
[EnvInject] - Variables injected successfully.

If I revert back to envinject 1.36, then it is defined and I see this in the console:

[EnvInject] - Preparing an environment for the job.
