Update environment from agent within a job

[christop...@googlemail.com]

Hi,

TLDR: while running a job on a (windows) agent, is there a way to refresh the environment from the agent to a shell- (actually bat-) step?

Whole story:

I want to test an application installer on a VM (I am resetting to a snapshot after the test).

After the installation I want to make sure installation worked well and all required components are available. Therfore I am starting parts of the application. Previously the installer required a reboot, that's why I set some environment variables (extension of PATH, etc...) manually.

Now we modified the installer to propagate the new enivronment using OS facilities. On a real PC with a human user this works well.

However it does not work within my jenkins job: environment is not available, even when I proceed the test in a new bat-step. Obviously that step is inheriting the environment from it's parent and that environment has not been updated.

FYI: for execution of the installer and test of the application I am using robotframework called from bat-steps.

Do you have any ideas for me how I can avoid my manual workaround and really test the installer environment?

Thanks in advance!

Christoph
