Jenkins pipeline pass all parameters down to downstream jobs

问题

I have a pipeline job named buildall which looks like this:

pipeline {
    stages {
        stage("job1") {
            build job: "job1"
        }
    }
}

The buildall job has 25 parameters. I would like to pass all of buildall's parameters down to job1. Is there an easy way I can do that, instead of manually specifying each parameter?

In this question: Pipeline pass parameters to downstream jobs a sub-question was asked but never answered: Or even better, is there a less cumbersome way in which I can just pass ALL the pipeline parameters to the downstream job.

That's the same question that I have.

回答1:

The following seems to work (I haven't tested it extensively though):

pipeline {
    agent any
    parameters {
        string(name: 'PARAM1', description: 'Param 1?')
        string(name: 'PARAM2', description: 'Param 2?')
    }
    stages {
        stage('Example') {
            steps {
                echo "${params}"
                script {
                    def myparams = currentBuild.rawBuild.getAction(ParametersAction).getParameters()
                    build job: 'downstream-pipeline-with-params', parameters: myparams
                }    
            }
        }
    }
}

Drawback: to access rawBuild and getAction you have to disable the Groove sandbox or approve these signatures in Jenkins under Manage Jenkins > In-process Script Approval. This dialog will show you that you might introduced a security vulnerability. So it depends on your environment if you want to take this risk or not.

回答2:

If you don't care about the parameter types, this approach does not require disabling the Groovy Sandbox - it simply assumes that all parameters can be treated as a string (won't work for "File", for example):

def myparams = params.collect{
    string(name: it.key, value: it.value)
}
build job: 'downstream-job', parameters: myparams

It wouldn't be too hard to expand the logic to handle predefined non-string parameter types, but I agree that this should not be necessary. A better approach would be to expose parameters in the format required by the build() DSL closure, including type specifics that are currently not visible via the "params" global variable, or perhaps to add a boolean, eg:

// I wish:
build job: 'downstream-job', includeMyParameters: true, parameters: anyExtras

回答3:

You can pass all your pipeline parameters with this :

def params=[]
env.getEnvironment().each{ k, v ->
        params.add(string(name:"${k}", value:"${v}"))
   }

def slaveJob = build job: 'BuildJob', parameters:params
