Jenkins声明性管道负载参数在前提条件下

Question

在 jenkins 声明式管道中，有一种方法可以执行前置条件，它应该从文件中加载构建参数。在 Jenkins 中有一个选项，我们可以重新启动单个阶段。因此，我希望每个阶段都从 groovy 文件中加载参数。

目前是

pipeline {
    agent any

        stage("Grep the values") {
            steps {
                load "${WORKSPACE}/file-parameter.groovy"
            }
        }


        stage("Perform Deploynment) {
            when {
                expression { "${Perform_Deployment}" == "true" }
            }

            steps {
                withCredentials([
                    usernamePassword(credentialsId: "LoginID", passwordVariable: "LoginPassword", usernameVariable: "LoginUser")
                ]) {
                    ansiblePlaybook (
                        playbook: "${WORKSPACE}/ansible-playbook.yml",
                        forks: 5,
                        extraVars: [
                            loginUser: "${LoginUser}",
                            loginPassword: "${LoginPassword}"
                        ]
                    )
                }
            }
        }
    }
}

如何在条件之前在阶段加载“${WORKSPACE}/file-parameter.groovy”。我的期望应该如下所示

pipeline {
    agent any

        stage("Grep the values") {
            steps {
                load "${WORKSPACE}/file-parameter.groovy"
            }
        }


        stage("Perform Deploynment) {
            load "${WORKSPACE}/file-parameter.groovy"
            when {

                expression { "${Perform_Deployment}" == "true" }
            }

            steps {
                withCredentials([
                    usernamePassword(credentialsId: "LoginID", passwordVariable: "LoginPassword", usernameVariable: "LoginUser")
                ]) {
                    ansiblePlaybook (
                        playbook: "${WORKSPACE}/ansible-playbook.yml",
                        forks: 5,
                        extraVars: [
                            loginUser: "${LoginUser}",
                            loginPassword: "${LoginPassword}"
                        ]
                    )
                }
            }
        }
    }
}

load 步骤返回 groovy 脚本在执行时返回的任何内容，因此您需要将其存储在变量中

file-parameter.groovy 可能如下所示：

return [
    performDeployment: true,
    // other variables
]

或者像这样

performDeployment = true

// other variables and methods

return this

在这两种情况下，您都可以像这样在管道中使用它：

stage("Grep the values") {
    steps {
        script {
            fileParams = load("${WORKSPACE}/file-parameter.groovy")
        }
    }
}

stage("Perform Deploynment) {
    when {
        expression { fileParams.performDeployment }
    }

我很确定您不需要进行字符串比较，您可以只使用布尔值。
