具有动态矩阵轴值的声明性管道

嗨，我正在尝试获得Jenknis-Declarative-Pipeline-Job作品。

用例应该非常简单：
我想使用相同的Jenkins管道构建多个插件。为此，我编写了一个“ JenkinsLibrary”，其接口可将插件用于参数。该参数之一是轴值。

我遇到的问题与this reddist post非常相似。

我想通过变量设置矩阵构建“轴”的“值”。 我没了主意，这有可能吗？

这是我的示例：
一个带有文件my_library.groovy

的“ JenkinsLibrary” 
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}"
                } }
            }
        } } }
    }
}

带有文件“ Jenkinsfile”的插件：

@Library("JenkinsLibrary") _

def options = [
    axis_values: "a_axis_value"
]

my_library(options)

我遇到以下错误：

[...] Expected string literal but got "${axis_1_values}"

完整日志：

    19: Expected string literal but got "${axis_1_values}" @ line 19, column 28.
                       values "${axis_1_values}" 
                              ^

更新
我仍然没有解决方案。但是当我定义这样的变量时，我了解到我尝试在该变量中插入“ GStringImpl”。但是我无法将其转换为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

但是我仍然不知道如何添加单个值，因为如果这样做

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.

这种强制转换的东西可能适用于单个值，但是我希望能够添加一个值列表，就像它在默认示例中可能适用的那样...
values "axis_2_value_A", "axis_2_value_B"

我想知道，这是否可以在声明式管道的“ docker-agent”部分中使用。

agent { 
    docker {
        image "${_image}:latest"
        label "${_label}"
    }
}

但是在代码中，我意识到docker-label的解析是单独实现的...

我仍然不知道如何在声明式管道的矩阵/轴特征内实现该目标。

（事实：这样做的主要原因之一是，蓝色海洋视图中脚本管道的可视化仍然存在问题，并且似乎忽略了这个问题...

1 个答案:

答案 0 :(得分：3)

从声明的插件v1.6.0开始，声明式管道不支持动态轴值。错误消息说它期望一个“文字字符串”值。也许消息还应该说：“不允许使用模板字符串，数组，变量或函数调用。”

这是设计使然，目的是防止管道作者被管道引擎的某些内部假设所困扰。可能有可能进行更改，但需要仔细的计划和测试。

请在https://issues.jenkins.io/提交JIRA和/或加入Jenkins Pipeline Authoring SIG，以帮助实现此功能。
