How to get the changes since the last successful build in jenkins pipeline?
This is what I've used:
def listFilesForBuild(build) {
def files = []
currentBuild.changeSets.each {
it.items.each {
it.affectedFiles.each {
files << it.path
}
}
}
files
}
def filesSinceLastPass() {
def files = []
def build = currentBuild
while(build.result != 'SUCCESS') {
files += listFilesForBuild(build)
build = build.getPreviousBuild()
}
return files.unique()
}
def files = filesSinceLastPass()
Well I managed to cobble something together. I'm pretty sure you can iterate the arrays better but here's what I've got for now:
node('Android') {
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;
}
Based on the answer from CaptRespect i came up with the following script for use in the declarative pipeline:
def changes = "Changes:\n"
build = currentBuild
while(build != null && build.result != 'SUCCESS') {
changes += "In ${build.id}:\n"
for (changeLog in build.changeSets) {
for(entry in changeLog.items) {
for(file in entry.affectedFiles) {
changes += "* ${file.path}\n"
}
}
}
build = build.previousBuild
}
echo changes
This is quite useful in stage->when->expression
parts to run a stage only when certain files were changed. I haven't gotten to that part yet though, I'd love to create a shared library from this and make it possible to pass it some globbing patterns to check for.
EDIT: Check the docs btw, in case you want to delve a little deeper. You should be able to convert all the object.getSomeProperty()
calls into just entry.someProperty
.
