Jenkins Pipeline的hasProperty函数

发哥随手记2023-07-27 19:55

函数的作用

用于判断某个参数或者字段是否存在。

用法

例子一

groovy 复制代码 
def projectStr = "P1,P2,P3"
pipeline {
    agent any

    parameters {
        extendedChoice(
                defaultValue: "${projectStr}",
                description: '选择要发布的项目',
                multiSelectDelimiter: ',',
                name: 'SELECT_PROJECTS',
                quoteValue: false,
                saveJSONParameterToFile: false,
                type: 'PT_CHECKBOX',
                value: "${projectStr}",
                visibleItemCount: 1000)
    }

    stages {
        stage('Git Pull') {
            steps {
                script {
                	// 判断参数字段是否存在
                    if (this.hasProperty("SELECT_PROJECTS")) {
                        echo "${SELECT_PROJECTS}"
                    } else {
                        echo "SELECT_PROJECTS is null"
                    }
                }
            }
        }
    }
}

出现的场景： 我想通过参数配置进来一个选择框列表，根据选择的情况做不同的处理；在过程中，我发首次构建Job的时候会报错误。错误如下：

原因是：可能是因为首次构建，parameters 中的extendedChoice还没有初始化好导致本次构建上线文没有SELECT_PROJECTS变量 。我又没有做提前判断，直接取值去判断的。 代码如下：

groovy 复制代码 
def projectStr = "P1,P2,P3"
pipeline {
    agent any

    parameters {
        extendedChoice(
                defaultValue: "${projectStr}",
                description: '选择要发布的项目',
                multiSelectDelimiter: ',',
                name: 'SELECT_PROJECTS',
                quoteValue: false,
                saveJSONParameterToFile: false,
                type: 'PT_CHECKBOX',
                value: "${projectStr}",
                visibleItemCount: 1000)
    }

    stages {
        stage('Git Pull') {
            steps {
                script {
                	// 不是使用hasProperty函数判断的，而是直接用变量判断的，所以会报错
                    if (null == SELECT_PROJECTS) {
                        echo "${SELECT_PROJECTS}"
                    } else {
                        echo "SELECT_PROJECTS is null"
                    }
                }
            }
        }
    }
}

遇到的问题

问题一

没有执行的权限，解决方法授权执行即可，具体怎么授权自行百度。

错误如下：
