How to get list of changed files since last build in Jenkins/Hudson

Question

I have set up Jenkins, but I would like to find out what files were added/changed between the current build and the previous build. I\'d like to run some long running tests

Answer 1

I tried to add that to comments but code in comments is no way:

Just want to prettify code from heroin's answer:

def changedFiles = []
def changeLogSets = currentBuild.changeSets
for (entries in changeLogSets) {
    for (entry in entries) {
        for (file in entry.affectedFiles) {
            echo "Found changed file: ${file.path}"
            changedFiles += "${file.path}"
        }
    }
}

Keep in mind for some cases git plugin returns empty changeSet, like:

• First run in newly created branch
• 'Build now' button build
