问题
Hi I am trying to get a Jenknis-Declarative-Pipeline-Job work.
The Use-Case should be pretty simple:
I want to build multiple Plugins with the same Jenkins-pipeline. To do so I wrote a "JenkinsLibrary" with an interface the Plugins can use for parameters. One of this parameters is the axis-values.
The Problem I have is pretty similar to this reddist post.
I want to set the "values" of the "axis" of the matrix-build from a variable. I am out of Ideas, is this even possible?
So here is my example:
a "JenkinsLibrary" with a file my_library.groovy
def call(Map i_options)
{
// later I will parse the options to set the values, but currently the step before already crashes ...
def axis_1_values = "axis_1_value_A"
// already tried the following alternatives ...
// def axis_1_values = 'axis_1_value_A'
// def axis_1_values = '''axis_1_value_A'''
// def axis_1_values = ["axis_1_value_A", "axis_2_value_A"]
pipeline
{
agent any
stages { stage("stage A") { matrix {
axes {
axis {
name "axis_1"
// values "axis_1_value_A" // <- of course this works ...
// but I want to read it from a variable
values "${axis_1_values}"
// I already tried more variants
// values ${axis_1_values}
// values axis_1_values
}
axis {
name "axis_2"
values "axis_2_value_A", "axis_2_value_B"
}
}
stages {
stage("another stage") { steps {
echo "hello world from ${axis_1} && ${axis_2}"
} }
}
} } }
}
}
A Plugin with a file "Jenkinsfile":
@Library("JenkinsLibrary") _
def options = [
axis_values: "a_axis_value"
]
my_library(options)
I am getting the following error:
[...] Expected string literal but got "${axis_1_values}"
complete log:
19: Expected string literal but got "${axis_1_values}" @ line 19, column 28.
values "${axis_1_values}"
^

Finished: FAILURE
My System:
Jenkins-Version: Jenkins ver. 2.190.1
Declarative-Plugin-Version 1.5.0
Declarative Agent API: 1.1.1
Declarative Extension Points API: 1.5.0
(many other plugins, I think this are the important ones)
UPDATE
I still do not have a solution. But when I define a variable like this, I understand that I try to insert a "GStringImpl" to that. But I am unable to cast it as java-string.
def _str_1 = "a string"
def _str_2 = "${_str_1}"
println _str_1.class // -> class java.lang.String
println _str_2.class // -> class org.codehaus.groovy.runtime.GStringImpl
def _str_3 = "${_str_1}" as java.lang.String
println _str_3.class // -> class java.lang.String
But I still don't know how I can add a single value, because if I do
values "${axis_1_values}" as as java.lang.String // error-msg: Expected string literal but got ${as}
values ("${axis_1_values}" as java.lang.String) // error-msg: Expected string literal but got ${"${axis_1_values}"
values axis_1_values.toString() // error-msg: Method calls on objects not allowed outside "script" blocks.
values "${axis_1_values}".toString() // error-msg: Expected a symbol @ line 26, column 28.
This casting stuff may work for a single value, but I want to be able to add a list of values, like its possible in the default example which works ...values "axis_2_value_A", "axis_2_value_B"
I am wondering, that this works in the "docker-agent"-part of the declarative pipeline.
agent {
docker {
image "${_image}:latest"
label "${_label}"
}
}
But I in the code, I realized that the parsing of the docker-label is implemented separately ...
I have still no Ideas how to reach that goal within the matrix / axis features of the declarative pipeline.
(funfact: one of the main reasons why even doing this that the visualisation in the blue-ocean view for scripted-pipelines is still buggy and the issue seems to be ignored ...

回答1:
What you are trying to achieve is to wrap a pipeline in a share library in order to reuse it as a template?
I suggest you try this library https://github.com/SAP/jenkins-pipelayer/
It implements a template system, you generate jobs based on property files, the variables between double curly brakets get replaced when the job is generated onto jenkins. https://github.com/SAP/jenkins-pipelayer/blob/master/USAGE.md#template-engine
The lib also resolves the issue we have with job parameters not beeing built at first run of the pipeline
