Is there a way to access updated system environment variable from Jenkins?

[rabie....@gmail.com]

I have an analysis number variable in my batch script that increments after every job build. I have to get this new value in my post build email notification. Jenkins job makes a copy of all system environment variables at the start up and this way I keep getting the same environment variable value in my post-build email, even though my analysis number environment variable stored in the system has incremented.  My question is there a way to access the system environment variable and not its copy stored in Jenkins?

Hello, IIUC your question then it's not really a Jenkins issue.

Spawned processes from Jenkins will inherit the values from environment from when it started.

IMO you should/could consider changing that design to retrieve this counter from somewhere Central (think a registry like zookeeper or consul, or even a dbms table possibly).

In any case using this environment var principle is going to prove complex, and even more when using Jenkins agents (where env is not the master's).

My 2 cents

I don't think there is a way. Are you using a source control system? You can store the variable value/pair into a property file. You can then commit it into your source as a post-build process. Otherwise, you can just store it in a property file located in the build server.
