emailext using groovy-html.template with environment variables issue

[amit r]

Hi All, 

i'm using jenkinsFile and for lone time using also the emailext plugin with some default params that were ok for now..

now i reached to some issues that i want to use in my groovy html template variables that were used in my jenkinsFile  - for example env variables.

its not clear to me how can i access them within the template..

the only thing i found online is the :

build.getEnvVars() but this one also give very limited info and not on my env variables that i used in my build..

in addition , see some examples online that use project.name or build.result ... how can i know which options i have to use in this template? 

on top of it:

in the jenkinsFile it self we have this section:

emailext(
        from: 'Jenkins',
        replyTo: 'none',
        recipientProviders: [[$class: 'CulpritsRecipientProvider'], [$class: 'DevelopersRecipientProvider'], [$class: 'RequesterRecipientProvider']],
        subject: '[Jenkins] ${PROJECT_NAME} - build #${BUILD_NUMBER} - ${BUILD_STATUS}',
        mimeType: 'text/html',
        to: '${GERRIT_CHANGE_OWNER_EMAIL}',
        body: '${SCRIPT, template="managed:groovy-html.template"}'
)

in the to: section i want to use the env variable "GERRIT_CHANGE_OWNER_EMAIL" but it not passing the value  ( i tried also with env.GERRIT_CHANGE_OWNER_EMAIL and also /${env.GERRIT_CHANGE_OWNER_EMAIL}

what is your suggestion to handle these cases?

thanks in advance!

Hi Amit,

 

(a) in your code/screenshot example the problem:

to: '${GERRIT_CHANGE_OWNER_EMAIL}',

[…]

in the to: section i want to use the env variable "GERRIT_CHANGE_OWNER_EMAIL" but it not passing the value  ( i tried also with env.GERRIT_CHANGE_OWNER_EMAIL and also /${env.GERRIT_CHANGE_OWNER_EMAIL}

… the problem is a Groovy one:

• Please replace the single quotes with double quotes to allow string interpolation

 

 

(b) And in the groovy html template code there are IMHO only certain variables explicitly injected:

• Based upon http://stackoverflow.com/a/9983405 and https://github.com/jenkinsci/email-ext-plugin/blob/master/src/main/java/hudson/plugins/emailext/plugins/content/ScriptContent.java please note the “binding.put(...)” calls, e.g.:
• build ... org.jenkinsci.plugins.workflow.job.WorkflowRun for Pipeline jobs
• project == build.getParent() ... org.jenkinsci.plugins.workflow.job.WorkflowJob - the job/project instance for this build
• it ... ScriptContentBuildWrapper(build) (internal ExtEmail class)
• rootUrl … Jenkins URL as set in your Jenkins configuration

 this one worked   - tnx for that!

 regard this part - i know these params but i'm sure that we can manipulate the template in some way to have values that no on build... for example , i have file in my workspace that contains all the values that i want to use in the mail, will it be available in the post in the template? can i import this file context into some map and use it in my email template? 

 as i know , we have already the option to run build.getEnvVars() but only for specific values that inside build context - not the env values that i'm looking for...

do you see other option for it?
