将参数从 KEY=VALUE 属性文件传递到下游 Jenkins 作业

Question

In my declarative pipeline, I do have the below line to call the downstream job.

build job: 'my_downstream_job'

I have a file in KEY=VALUE format, how to pass in the parameters from this properties file? Downstream job receive this parameter as KEY . Using Jenkins GUI, I use "Parameters from properties file" and put this filename in there and it works, like to know how to do the same with pipeline.

Answer 1

You might need some extra logic to process this file and construct the appropriate list. See https://jenkins.io/doc/pipeline/steps/pipeline-build-step/ for documentation but typically it will look like:

build(job: "my_downstream_job",
    parameters: [
        new StringParameterValue('MY_NAME', myname_var),
    ],
    propagate: true
)

So you might need to parse your file and create a list if new StringParameterValue's for each line.

Answer 2

It doesn't appear that there is a one-liner way to do this, but I got this to work:

params = readProperties  file: "params.properties"
build job: 'some_jenkins_job', parameters: [
    string(name: 'PROP_STR', value: params.PROP_STR),
    booleanParam(name: 'PROP_BOOL', value: params.PROP_BOOL),
]

And maybe this is for the best, so it's clear exactly which params are being passed in, just by reading the Jenkinsfile.
