函數(shù)的作用
用于判斷某個(gè)參數(shù)或者字段是否存在。
用法
例子一
def projectStr = "P1,P2,P3"
pipeline {
agent any
parameters {
extendedChoice(
defaultValue: "${projectStr}",
description: '選擇要發(fā)布的項(xiàng)目',
multiSelectDelimiter: ',',
name: 'SELECT_PROJECTS',
quoteValue: false,
saveJSONParameterToFile: false,
type: 'PT_CHECKBOX',
value: "${projectStr}",
visibleItemCount: 1000)
}
stages {
stage('Git Pull') {
steps {
script {
// 判斷參數(shù)字段是否存在
if (this.hasProperty("SELECT_PROJECTS")) {
echo "${SELECT_PROJECTS}"
} else {
echo "SELECT_PROJECTS is null"
}
}
}
}
}
}
出現(xiàn)的場景： 我想通過參數(shù)配置進(jìn)來一個(gè)選擇框列表，根據(jù)選擇的情況做不同的處理；在過程中，我發(fā)首次構(gòu)建Job的時(shí)候會(huì)報(bào)錯(cuò)誤。錯(cuò)誤如下：

原因是：可能是因?yàn)槭状螛?gòu)建，parameters 中的extendedChoice還沒有初始化好導(dǎo)致本次構(gòu)建上線文沒有SELECT_PROJECTS變量 。我又沒有做提前判斷，直接取值去判斷的。 代碼如下：文章來源：http://www.zghlxwxcb.cn/news/detail-614415.html
def projectStr = "P1,P2,P3"
pipeline {
agent any
parameters {
extendedChoice(
defaultValue: "${projectStr}",
description: '選擇要發(fā)布的項(xiàng)目',
multiSelectDelimiter: ',',
name: 'SELECT_PROJECTS',
quoteValue: false,
saveJSONParameterToFile: false,
type: 'PT_CHECKBOX',
value: "${projectStr}",
visibleItemCount: 1000)
}
stages {
stage('Git Pull') {
steps {
script {
// 不是使用hasProperty函數(shù)判斷的，而是直接用變量判斷的，所以會(huì)報(bào)錯(cuò)
if (null == SELECT_PROJECTS) {
echo "${SELECT_PROJECTS}"
} else {
echo "SELECT_PROJECTS is null"
}
}
}
}
}
}
遇到的問題
問題一
沒有執(zhí)行的權(quán)限，解決方法授權(quán)執(zhí)行即可，具體怎么授權(quán)自行百度。
錯(cuò)誤如下：文章來源地址http://www.zghlxwxcb.cn/news/detail-614415.html
