Jenkins Pipeline的hasProperty函数
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
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：
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：
