FYI.
Here is my final solution:
pipeline {
agent any
stages {
stage('Conventional Analysis') {
steps {
script {
echo "GERRIT_CHANGE_SUBJECT: ${GERRIT_CHANGE_SUBJECT}"
def changeSubj = "$GERRIT_CHANGE_SUBJECT".trim()
def match = (changeSubj =~ /^(build|chore|ci|docs|feat|fix|perf|refactor|revert|style|test)(\([a-z]+\))?:\s.+$/)
if (!match) {
echo "Non-Conventional Commit: \n${changeSubj}"
error("Commit message does not follow conventional commit format")
} else {
echo "Conventional Commit: \n${changeSubj}"
}
}
}
}
stage('Change-Id Required') {
steps {
script {
echo "GERRIT_CHANGE_COMMIT_MESSAGE: ${GERRIT_CHANGE_COMMIT_MESSAGE}"
def encodedString = "$GERRIT_CHANGE_COMMIT_MESSAGE"
def decodedBytes = java.util.Base64.decoder.decode(encodedString)
def commitMessage = new String(decodedBytes, "UTF-8")
// trim for each line and filter out the empty line
def lines = commitMessage.split('\n').collect { it.trim() }.findAll { it }
def changeIdCount = lines.count { it.startsWith('Change-Id: ') }
if (changeIdCount < 1) {
errors("Change-Id is required.")
}
if (changeIdCount > 1) {
// Change-Id: occurrences are over than 1
errors("Change-Id occurrences are over than 1. Please remove the redundant.")
}
}
}
}
}
}
