如何将环境变量传递给jenkinsfile的下游

Question

I am running Jenkins on a windows machine. How can I pass environment variables like %BUILD_NUMBER% to a downstream job? I am using below piece of code but that is not working as expected, it is printing the same thing again in output

build job: 'DeployBuild', parameters: [string(name: 'BuildId', value: $env:BUILD_NUMBER)], wait: false

The output I am getting:

C:\JenkinsBuilds\jobs\DeployBuild\workspace>echo $env:BRANCH_NAME-$env:BUILD_NUMBER 
$env:BRANCH_NAME-$env:BUILD_NUMBER
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

Expected Output:

C:\JenkinsBuilds\jobs\DeployBuild\workspace>echo TESTJob-12
TESTJob-12
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

Tried multiple patterns like ${BUILD_NUMBER}, $BUILD_NUMBER %BUILD_NUMBER but none is giving the expected output.

Answer 1

您可以尝试发送env.BUILD_NUMBER或“ $ {BUILD_NUMBER}”或“ env.BUILD_NUMBER”，然后注意双引号字符串插值仅发生在双引号中。

Answer 2

Put the value: $env:BUILD_NUMBER) as value: ${env.BUILD_NUMBER} . This will do it. So total code will be like:

build job: 'DeployBuild', parameters: [string(name: 'BuildId', value: ${env.BUILD_NUMBER})], wait: false
