"在 Jenkins 构建的 Windows Powershell 中设置的变量，在其他构建步骤中不可用"

Question

I have a Jenkins build with one parameter called VERSION.

           if ("$ENV:VERSION".length -eq 4)
        {
           $ENV:VERSION = "$ENV:VERSION",3 -join ""  (here it will be 18103)
         }

         Write-Output "$ENV:VERSION" (18103 here aswell)

Answer 1

This is a general issue with environment variable scope. Every process inherits the environment variables from its parent, but has its own copy, and any modifications you make will only be reflected in the current process and child processes.

I think you will have to find some way to pass the value to a future step that doesn't rely on environment variables.

Answer 2

You can try to use EnvInject Plugin and set additional PROJ_VERSION=$ENV:VERSION variable in your job. In this case it should be working correctly. If it isn't working within Properties Content directly, try to use injection via file as in this example.

Answer 3

I found another option which works in Freestyle project jobs.

the 1st powershell step:

[Environment]::SetEnvironmentVariable('IMAGE_VERSION', $imageVersion, 'Machine')

the 2nd powershell step:

$imageVersion = [Environment]::GetEnvironmentVariable('IMAGE_VERSION', 'Machine')
