How can I pass a value from a TeamCity failure Condition to an e-mail notification? - kotlin

Question

I want to show the status of the build in an e-mail with just a simple FAIL or PASS text appear in the body. There does not seem to be any kind of predefined "buildStatus" variable that I can access or setup in TeamCity. I guess I need to access the "failureConditions" function at bottom but not sure how, tried lots of things but nothing worked, this is my script:
package _Self.buildTypes
import jetbrains.buildServer.configs.kotlin.v2019_2.failureConditions.BuildFailureOnText
import jetbrains.buildServer.configs.kotlin.v2019_2.failureConditions.failOnText
import jetbrains.buildServer.configs.kotlin.v2019_2.triggers.schedule
allowExternalStatus = true
params {
param("MinorVersion", "0")
param("RevisionVersion", "0")
}
powerShell {
name = "Email"
scriptMode = script {
content = """
function Send-ToEmail([string]${'$'}email, [string]${'$'}attachmentpath){
${'$'}message = new-object Net.Mail.MailMessage;
${'$'}message.From = "teamcity#blog.com";
${'$'}message.To.Add(${'$'}email);
${'$'}message.Subject = "%env.TEAMCITY_PROJECT_NAME% | %VersionNumber% ";
${'$'}message.Body = "The build: PASS or FAIL text here";
${'$'}smtp = new-object Net.Mail.SmtpClient("blog.local", "25");
${'$'}smtp.EnableSSL = ${'$'}true;
${'$'}smtp.send(${'$'}message);
write-host "Mail Sent" ;
}
Send-ToEmail -email "me#blog.com" -attachmentpath ${'$'}path;
""".trimIndent()
}
}
}
failureConditions {
failOnText {
conditionType = BuildFailureOnText.ConditionType.CONTAINS
pattern = "FAIL"
reverse = false
}
}

To solve this in T/C:
Create new custom env. var. e.g. MyBuildStatus
Create new build step e.g. Set build status (only executes if build successful)
Create a new Parameter name='env.MyBuildStatus.Status' value='SUCCESS'
Add variable to email subject: $message.Subject = "%env.MyBuildStatus.Status%
Why T/C has no build in "buildstatus" env. variable is interesting.
