Jenkins:将用户定义的变量传递给Email-Ext插件 [英] Jenkins: Passing user defined variables to Email-Ext plugin

问题描述

我正在使用Email-Ext插件在声明式管道的后期构建阶段的构建结束时发送结果电子邮件.在电子邮件的正文中，我尝试插入一些环境变量和一些用户定义的环境变量.

I'm using the Email-Ext plugin to send a results email at the end of my build in the post build stage of a declarative pipeline. In the body of the email I'm trying to insert some environment variables and some user defined environment variables.

内置变量显示良好，但是我定义的任何用户定义变量在电子邮件正文中都为空，或者在attachmentPattern字段中也不起作用:

The built in variables show up fine, however any user defined variables I define are just empty in the body of the email or don't work in the attachmentPattern field either:

我的环境变量:

pipeline {
    agent any
    environment {
        buildFolder = "build_${BUILD_NUMBER}" 
        robotFolder = "build_${BUILD_NUMBER}/robotDemo" 
        serverName = "abc123"
        robotResults = "${buildFolder}/*.txt"
    }

我在帖子中使用的email-ext格式{}版本:

The email-ext format I am using in my post{} build:

emailext attachLog: true, attachmentsPattern: 'build_${env.BUILD_NUMBER}/Robot_Results.txt', body: '<b>Job Name:</b> ${ENV, var="JOB_NAME"}<br><b>Build Number:</b> ${ENV, var="BUILD_NUMBER"}<br><br><b>Build URL:</b><br>${ENV, var="BUILD_URL"}<br><br><b>Log Files:<br><br><br><pre>${BUILD_LOG_EXCERPT, start="^====", end="^report.html"}</pre><pre>${ENV, var="serverName"}</pre>', mimeType: 'text/html', subject: 'ABS Results', to: '[e-mail]'

例如:$ {ENV，var ="JOB_NAME"}，显示正常.但是$ {ENV，var ="serverName"}根本不显示.

For example: ${ENV, var="JOB_NAME"}, shows up fine. However ${ENV, var="serverName"} doesn't show at all.

我尝试了诸如...

$ {serverName}
$ {env.serverName}

...但是它们也不起作用.

...but they don't work either.

有什么想法如何在email-ext插件中使用用户定义的环境变量，例如上面的"serverName"?

Any ideas how to use user defined environment variables like 'serverName' above in the email-ext plug-in?

感谢&最好的问候，理查德.

Thanks & best regards, Richard.

推荐答案

您使用的是单引号，但只有双引号允许对变量进行插值.

You’re using single quotes, but only double quotes allow variables to be interpolated.

我建议您使用Groovy脚本来呈现电子邮件内容.

I would suggest you to use a Groovy script for rendering the email contents.

您可以使用

或添加自己的模板，如文档中所述 .我无法确定是否可以从工作空间中加载该模板，但是您可以尝试以下操作:

Or add your own template like described in the documentation. I couldn't figure our if it's possible to load that template from the workspace, but you could try it with:

emailext body: '''${SCRIPT, template="$WORKSPACE/groovy-html.template"}'''

在插值时从环境或参数获取值的语法为:

The syntax for getting values from the environment or parameters when interpolating is:

${env.MY_ENVVAR}
${param.MY_BUILDPARAM}

(env和param是保存所有值的ja Groovy映射)

(env and param is ja Groovy map holding all the values)

对于所有其他变量:

${varName}
