Access environment variable in email ext template using Jenkins pipeline

[srivathsa...@gmail.com]

I am trying to attach the template file using Jenkins pipeline, emailext. 

Variable (PROJNAME) is not accessible in the template file and I am receiving exceptions as an email:

Exception raised during template rendering: No such property: env for class: SimpleTemplateScript21 groovy.lang.MissingPropertyException: No such property: env for class: SimpleTemplateScript21 at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53) at org.codehaus.groovy.runtime.callsite.PogoGetPropertySite.getProperty(PogoGetPropertySite.java:52) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGroovyObjectGetProperty(AbstractCallSite.java:307) at SimpleTemplateScript21.run(SimpleTemplateScript21.groovy:1) at groovy.text.SimpleTemplateEngine$SimpleTemplate$1.writeTo(SimpleTemplateEngine.java:168) at groovy.text.SimpleTemplateEngine$SimpleTemplate$1.toString(SimpleTemplateEngine.java:180) at hudson.plugins.emailext.plugins.content.ScriptContent.renderTemplate(ScriptContent.java:151) at hudson.plugins.emailext.plugins.content.ScriptContent.evaluate(ScriptContent.java:82) at org.jenkinsci.plugins.tokenmacro.DataBoundTokenMacro.evaluate(DataBoundTokenMacro.java:208) at org.jenkinsci.plugins.tokenmacro.Parser.processToken(Parser.java:308) at org.jenkinsci.plugins.tokenmacro.Action$KiHW1UeqOdqAwZul.run(Unknown Source) at org.parboiled.matchers.ActionMatcher.match(ActionMatcher.java:96) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.matchers.SequenceMatcher.match(SequenceMatcher.java:46) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.matchers.FirstOfMatcher.match(FirstOfMatcher.java:41) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.matchers.FirstOfMatcher.match(FirstOfMatcher.java:41) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.matchers.ZeroOrMoreMatcher.match(ZeroOrMoreMatcher.java:39) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.matchers.SequenceMatcher.match(SequenceMatcher.java:46) at org.parboiled.parserunners.BasicParseRunner.match(BasicParseRunner.java:77) at org.parboiled.MatcherContext.runMatcher(MatcherContext.java:351) at org.parboiled.parserunners.BasicParseRunner.run(BasicParseRunner.java:72) at org.parboiled.parserunners.ReportingParseRunner.runBasicMatch(ReportingParseRunner.java:86) at org.parboiled.parserunners.ReportingParseRunner.run(ReportingParseRunner.java:66) at org.parboiled.parserunners.AbstractParseRunner.run(AbstractParseRunner.java:81) at org.parboiled.parserunners.AbstractParseRunner.run(AbstractParseRunner.java:76) at org.jenkinsci.plugins.tokenmacro.Parser.process(Parser.java:68) at org.jenkinsci.plugins.tokenmacro.TokenMacro.expand(TokenMacro.java:204) at org.jenkinsci.plugins.tokenmacro.TokenMacro.expandAll(TokenMacro.java:234) at hudson.plugins.emailext.plugins.ContentBuilder.transformText(ContentBuilder.java:80) at hudson.plugins.emailext.ExtendedEmailPublisher.addContent(ExtendedEmailPublisher.java:862) at hudson.plugins.emailext.ExtendedEmailPublisher.createMail(ExtendedEmailPublisher.java:741) at hudson.plugins.emailext.ExtendedEmailPublisher.sendMail(ExtendedEmailPublisher.java:451) at hudson.plugins.emailext.EmailExtStep$EmailExtStepExecution.run(EmailExtStep.java:224) at hudson.plugins.emailext.EmailExtStep$EmailExtStepExecution.run(EmailExtStep.java:163) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1$1.call(AbstractSynchronousNonBlockingStepExecution.java:47) at hudson.security.ACL.impersonate(ACL.java:260) at org.jenkinsci.plugins.workflow.steps.AbstractSynchronousNonBlockingStepExecution$1.run(AbstractSynchronousNonBlockingStepExecution.java:44) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)

Pipeline Script:

stage('Email') {

    def mailRecipients = "mye...@abc.com"

    def jobStatus = currentBuild.currentResult

    env.PROJNAME = 'project_name'

    echo "projname is ${PROJNAME}"

    emailext body: '''${SCRIPT, template="test.template"}''',

        mimeType: 'text/html',

        subject: "[Jenkins] ${jobStatus}",

        to: "${mailRecipients}"

}

Template (filename - test.template):

<!DOCTYPE html>

<html>

<head>

<title>Page Title</title>

</head>

<body>

<h1>This is a Heading</h1>

<p>Job is '${env.PROJNAME}'</p>

</body>

</html>

Also tried replacing the variable syntax as "${PROJNAME}" and "${ENV, var="PROJNAME"}" but no luck. Any suggestions?

Thanks in advance.

You can use ENV(var="PROJNAME") when using a script template. This should work for all tokens.

Didn't help when I replaced with ENV(var="PROJNAME") in template file. I received the email as:

##################################
This is a Heading

Job is ENV(var="PROJNAME")
