global environment variables are not expanded (interpolated) in pipelines

XMLWordPrintable

      On Freestyle jobs defining a Jenkins global variable like this would work as expected:

      XDG_CACHE_HOME=${HOME}/.cache/${EXECUTOR_NUMBER}

      Note: behavior is the same regardless if brackets are used or not when you define the variables.

       

      Freestyle "set" result (correct):

      XDG_CACHE_HOME=/home/builder/.cache/2

      Pipeline "set" result (incorrect):

      XDG_CACHE_HOME=${HOME}/.cache/${EXECUTOR_NUMBER}

       

      This problem is essential because it prevents Jenkins administrators from using environment variables to fix/workaround execution problems. 

      Effectively this breaks any job that needs to define variables that are relative to something else, like workspace, home, ....

          Do you have EnvInject plugin installed? IIRC Global Env Vars get resolved in such way only if the plugin is installed, but I am not 100% sure.

          Yes, EnvInject plugin is installed but we are not using it.

          It impacts the environment resolution anyway IIRC

          Glad to see that a fix is in review. A link to PR would have being useful too.
