Get all change logs of since last successful build in Jenkins Pipeline

Question

In my Jenkins pipeline, I can get change logs of the current build by this.

def changeLogSets = currentBuild.changeSets

Is there a way to get all change-logs since last successful build?

Answer 1

You may try something like this:

node('my_kubernetes_pod') {
    passedBuilds = []

    lastSuccessfulBuild(passedBuilds, currentBuild);

    def changeLog = getChangeLog(passedBuilds)
    echo "changeLog ${changeLog}"
}

def lastSuccessfulBuild(passedBuilds, build) {
    if ((build != null) && (build.result != 'SUCCESS')) {
        passedBuilds.add(build)
        lastSuccessfulBuild(passedBuilds, build.getPreviousBuild())
    }
}

@NonCPS
def getChangeLog(passedBuilds) {
    def log = ""
    for (int x = 0; x < passedBuilds.size(); x++) {
        def currentBuild = passedBuilds[x];
        def changeLogSets = currentBuild.rawBuild.changeSets
        for (int i = 0; i < changeLogSets.size(); i++) {
            def entries = changeLogSets[i].items
            for (int j = 0; j < entries.length; j++) {
                def entry = entries[j]
                log += "* ${entry.msg} by ${entry.author} \n"
            }
        }
    }
    return log;
}

Additionally, you may try out "Changes Since Last Success Plugin": https://wiki.jenkins.io/display/JENKINS/Changes+Since+Last+Success+Plugin

But it will not work together with pipeline, this is a separate approach.

As I found may be this will helps you. With this you can fetch latest successful build change log file of any project build with Jenkins.

$DirectoryA = "D:\Jenkins\jobs\projectName\builds"  ####Jenkind directory
$firstfolder = Get-ChildItem -Path $DirectoryA | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1
$DirectoryB = $DirectoryA + "\" + $firstfolder

$sVnLoGfIle = $DirectoryB + "\" + "changelog.xml" 

write-host $sVnLoGfIle
