I am using email ext syntax to send the email in pipeline as code and having an HTML template to send the email.

I need to access the Jenkins environment variable in HTML template. It is working for standard environment variables like BUILD_URL. But it is not working for environment variable set with env.VARIABLE='VALUE'. If I try to access ${VARIABLE} in HTML template it is not working.

Any idea please.

To get environment variables in your template, you should use some scripts to access Jenkins API.

In Jenkins there are two most popular options that I know: Groovy templates and Jelly templates.

Some more info you can find on Email-ext plugin page.

I have the same problem here: Access custom environment variables in jelly template, but I was able to get access to build parameters.

Here is a template how to do that with Jelly:

<?jelly escape-by-default='true'?>
<!DOCTYPE html [
    <!ENTITY nbsp "&#38;#38;nbsp&#59;">
]>
<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:d="jelly:define">
<head>
  <style>
      body table, td, th, p, h1, h2 {
      margin:0;
      font:normal normal 100% Georgia, Serif;
      background-color: #ffffff;
      }
  </style>
</head>
<body>
<j:set var="buildEnv" value="${build.getEnvironment(listener)}" />
<j:set var="myVar" value="${buildEnv.get('MY_BUILD_PARAMETER')}" />
  <table>
    <tr>
      <td>Variable</td>
      <td>
        <p>${myVar}</p>
      </td>
    </tr>
  </table>
</div>
</body>
</j:jelly>

So, you just need add some jelly tags, and to get build parameters value in this templates you need call getEnvironment method from build object.

<j:set var="buildEnv" value="${build.getEnvironment(listener)}" />
<j:set var="myVar" value="${buildEnv.get('MY_BUILD_PARAMETER')}" />

  • @sanjiv can you please share how did you sued the SCRIPT (script token) inside pipeline / JenkinsFile...? I am not able to do so... – Doron Shai May 23 '17 at 12:44

Below text in Jenkins File worked for me

env.CURRENT_BRANCH = master
env.PIPELINE_TYPE = mytype

Below lines in Jelly\HTML file

Using the below variable all the environment variables defined in Jenkins can be accessible

${customEnvVar.PIPELINE_TYPE}-${customEnvVar.CURRENT_BRANCH}

Before this code customEnvVar needs to defined

< j:set var="customEnvVar" value="${it.getAction('org.jenkinsci.plugins.workflow.cps.EnvActionImpl').getOverriddenEnvironment()}"/>
