Fix groovy Script to mail to multiple receipients

monitoringemail.groovy file has below cal def:

def call(details = "") {
    def emailBody = "Build URL: " + env.Build_URL + '\n\n'
    emailBody += details
    mail( to: 'monitoring@company.com',
        subject: "Build failed in Jenkins:" + currentBuild.projectName + " " + currentBuild.fullDisplayName,
        body: emailBody)
}

and this monitoringemail.groovy file right now called in Jenkinsfile using method like monitoringemail() to send mail notification.

monitoringemail()
Ex:
Inside Jenkinsfile we will groovy file using method:

failure {
            monitoringemail()
        }

I want declare below email variables in monitoringemail.groovy file

NW_TEAM = 'net1 net2'
JOBDSL_OWNER = 'jobdsl'
CLIENT_TEAM = 'client1 client2 client3'
CD_JOB_OWNERS = 'cd1 cd2 cd3'
QA_OWNERS = 'staging1 staging3 staging4'

and update th monitoringemail.groovy file so i can call the

monitoringemail() using parameters.

monitoringemail()

monitoringemail(NW_TEAM)

monitoringemail(NW_TEAM,CLIENT_TEAM)

monitoringemail() means i can send email to infra@company.com by default

monitoringemail(NW_TEAM) means i can send email to net1@company.com and net2@company.com

monitoringemail(NW_TEAM,CLIENT_TEAM) means i can send email to net1@company.com, net2@company.com, client1@company.com, client2@company.com and client3@company.com

** TASK ** is to update monitoringemail.groovy file to support multiple parameters. right now as soon as we call method monitoringemail()its sending mails to monitoring@company.com.

We want kill this "monitoring@company.com" address usage and call explicitly monitoringemail(NW_TEAM) or monitoringemail(NW_TEAM, CLIENT_TEAM) so monitoringemail.groovy has capabilities so it can send emails to respective team user emails alerts.

Requirement changed a bit: (Need to enum and a seperate file)

JobOwner.groovy
enum JobOwner {
    NW_TEAM('net1, net2'),
    JOBDSL_OWNER('jobdsl'),
    CLIENT_OWNERS('client1, client2, client3'),
    CD_JOB_OWNERS('cd1,cd2'),
    QA_OWNERS('staging1, staging2, staging3')
 
    String recipients
 
    JobOwner(String recipients) {
        this.recipients = recipients
    }
 
    List<String> getRecipients() {
        return recipients.split(',').collect { it.trim() }
    }
}


sendEmail.groovy
def sendEmail(details = "", JobOwner... teams) {
    def recipients = teams.collect { it.getRecipients() }.flatten()
 
    recipients = recipients ?: ['infra'] 
 
    recipients.each { recipient ->
        def emailRecipient = recipient + "@company"
        def emailBody = "Build URL: " + env.Build_URL + '\n\n'
        emailBody += details
 
        mail(to: emailRecipient,
             subject: "Build failed in Jenkins: ${currentBuild.projectName} ${currentBuild.fullDisplayName}",
             body: emailBody)
    }
}

How does this look now

Here is a simple way to do that:

NW_TEAM = [
   "net1@company.com", 
   "net2@company.com"
]
JOBDSL_OWNER = ["jobdsl@company.com"]
CLIENT_TEAM = [
   "client1@company.com", 
   "client2@company.com", 
   "client3@company.com"
]
CD_JOB_OWNERS = [
   "cd1@company.com", 
   "cd2@companyd.com", 
   "cd3@company.com" 
]
QA_OWNERS = [
   "staging1@company.com", 
   "staging3@company.com", 
   "staging4@company.com"
]

def sendEmail(toEmail = ['infra@company.com'], details = "") {
    mail( to: toEmail.join(" "),
        subject: "Build failed in Jenkins: ${currentBuild.projectName} ${currentBuild.fullDisplayName}",
        body: """
Build URL: ${env.Build_URL}

${details}
""")
}

I've taken advantage of some Groovy features to shorten things a bit more. There's more ways to make this even more flexible, but this should meet what you wanted to do.

So sendEmail has been renamed from call. And now you send a list of email addresses you want to send things to.

sendEmail()  // sends to infra@company.com
sendEmail(NW_TEAM)   // sends to NW_TEAM = [ 'net1@company.com', 'net2@company.com' ]
sendEmail(NW_TEAM + CLIENT_TEAM) // sends to NW_TEAM and CLIENT_TEAM
sendEmail(NW_TEAM + CLIENT_TEAM + CD_JOB_OWNERS, "Some Important Details...")
