How to load variables from file into windows environment variables in Jenkins pipeline?

[Mark Allison]

I have the following Jenkinsfile

    node  {
    stage 'checkout'
    deleteDir()
    checkout scm
   
    load 'LoadTheseVariables.txt'  
   
    echo "MYKEY: ${MYKEY}"
    echo "REPO: ${REPO}"
   
    bat 'echo MYKEY is %MYKEY%'
    bat 'echo REPO is %REPO%'        
    }

The file LoadTheseVariables.txt contains:

    MYKEY="ThisIsTheKey"
    REPO="ThisIsTheRepo"

The output of the Jenkins build is:

    <..snip..>
    [Pipeline] load
    [Pipeline] { (LoadTheseVariables.txt)
    [Pipeline] }
    [Pipeline] // load
    [Pipeline] echo
    MYKEY: ThisIsTheKey
    [Pipeline] echo
    REPO: ThisIsTheRepo
    [Pipeline] bat
    [test] Running batch script
   
    D:\Jenkins\workspace\test>echo MYKEY is  
    MYKEY is
    [Pipeline] bat
    [test] Running batch script
   
    D:\Jenkins\workspace\test>echo REPO is  
    REPO is
    [Pipeline] }
    [Pipeline] // node
    [Pipeline] End of Pipeline
    Finished: SUCCESS

The Jenkins pipeline can see the variables but why can't my windows cmd environment see the variables? I even tried this step before the `bat` commands at the end: `bat 'refreshenv'` but that didn't reload the environment with those variables.

How can I load variables from a file in a Windows job and have them loaded into the environment at run time?

These are just Groovy variables. You didn't specify for them to be passed to launched processes' environment (as e.g. build parameters automatically are).

withEnv(…) should work.

env.VAR = 'value' probably too, but am not sure whether that's a recommended approach.

Thanks, simply using double quotes instead of single works fine.

bat "echo MYKEY is %MYKEY%"

Unexpected. Looks like I learned something new today. Thanks!
