使用 groovy 从 GIT 提交消息中提取 Jira 票证

Question

I'm writing Jenkins pipeline in which I'm extracting Jira tickets from GIT commit message.I'm using JIRA ID regex. How can I process a multiline string? I also have to display commit messages which do not contain any valid ticket ID's. How can I do that using the if-else loop in groovy? Below logic works for a single line, but not working for multi-line.

def commit = """new change
CO-10389
SRE-1234"""

def regex = (/[\s|]?([A-Z]+-[0-9]+)[\s:|]?/) 

if(commit =~ regex){
    def jira = commit.readLines().findAll(/[\s|]?([A-Z]+-[0-9]+)[\s:|]?/)
    println jira
} else {
    println commit
}

Multiline regex won't help you if you want to process also mis-matching lines, so you should be processing your text line-by-line:

import java.util.regex.Matcher

def commit = """new change
CO-10389
CO-
SRE-1234"""

commit.eachLine{ l ->
  switch( l ){
    case ~/[\s|]?([A-Z]+-[0-9]+)[\s:|]?/:
      println "JIRA: ${Matcher.lastMatcher[0][1]}"
      break
    default:
      println "no JIRA $l"
  }
}

prints

no JIRA new change
JIRA: CO-10389
no JIRA CO-
JIRA: SRE-1234
