View Last Changes Plugin on the plugin site for more information.

The simplest way to know what has changed on your Jenkins builds!.


The plugin uses diff2html to show last changes of a given build via VCS diffs, example:

Or using side-by-side configuration:



Last changes means compare current repository revision with an old revision. By default the plugin will diff current and previous revision.

Only Git and Svn based projects are supported. 


The main objective of this plugin is to have fast access to what has changed on a Jenkins build.
Another interesting aspect is that it can easily help to find the root cause of a failling build by highlighting what has changed.

And finally the plugin shines in a continuous delivery environment, where each commit generates a release candidate.

How it works?

  1. This plugin expects .git or .svn folders present on your build workspace and will use it to retrieve repository information .

  2. While your job runs the plugin reads your build workspace to retrieve the current VCS revision;

  3. The diff between actual and a previous revision will be stored; Note that the previous revision can be:

    • A provided revision id;

    • Revision of Last successful build;

    • Revision of an specific build;
    • Revision of Last tag;


      By default previous revision is current revision -1.



      You can use parameters in specificRevision parameter. In case of git, expressions like HEAD^{tree}or HEAD^^ can be used.
  4. The diff for each build can be viewed later in html format.

To get most from this plugin use periodically SCM pooling to trigger your builds, more details here.

The plugin always compare current revision with previous one even no new commit has been made. Since version 1.0.7 it is possible to provide a specific revision.


After installation just activate the post build action named Publish Last Changes.

  1. Activate post build action:  
  2. Last changes menu should be available
  3. Build changes history, each link will take you to the changes of the build  
  4. Last changes menu is available for builds that published changes. It will also take you to the changes published by the build



Since version 2.3 the commits between revisions are listed as below:




You can also see what has changed on a specific commit by clicking on it:


commit changes




The setup is done via build configuration and basically reflects diff2html options:


The possible values for Since attribute is Previous revision (the default), Last successful build and Last tag.


If SpecificRevision parameter is provided then Since configuration will be ignored and the diff will be done with provided revision id.


Advanced configuration reflects diff2html options:

Jenkins pipeline step


Following is an example of pipeline step using this plugin:

node {
      stage ('Build') {
           svn 'https://subversion.assembla.com/svn/cucumber-json-files/trunk/'
           step([$class: 'LastChangesPublisher', since:'PREVIOUS_REVISION',specificRevision: '', format: 'LINE', matchWordsThreshold: '0.25', matching: 'NONE', matchingMaxComparisons: '1000', showFiles: true, synchronisedScroll: true])



Pipeline DSL

Following are examples of pipeline dsl usage:


node {
     git 'https://github.com/jenkinsci/last-changes-plugin.git'
     lastChanges() //will use defaults


Parameters should be declared as key: 'value' as example below:


node {
     git 'https://github.com/jenkinsci/last-changes-plugin.git'
     lastChanges format:'SIDE',matching: 'WORD', specificRevision: 'c546ec31e854de3f27755273d3e1db6185aee4b4'


Or using declarative pipeline


pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                git 'https://github.com/jenkinsci/last-changes-plugin.git'
                lastChanges since: 'LAST_SUCCESSFUL_BUILD', format:'SIDE',matching: 'LINE'


Or using build params for specificRevision:


pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                git 'https://github.com/jenkinsci/last-changes-plugin.git'
                lastChanges format:'SIDE',matching: 'WORD', specificRevision: "${REV}"


Refer to parameterized builds to use parameters.


Pipeline scripting


Since v2.5 is possible to invoke LastChanges inside groovy script, instead of just declaring it as we saw above. See example below:

node {
      stage("checkout") {
        git url: 'https://github.com/jenkinsci/last-changes-plugin.git'

      stage("last-changes") {
        def publisher = LastChanges.getLastChangesPublisher "PREVIOUS_REVISION", "SIDE", "LINE", true, true, "", "", "", "", ""
              def changes = publisher.getLastChanges()
              for (commit in changes.getCommits()) {
                  def commitInfo = commit.getCommitInfo()



See model classes to know what can be accessed in pipeline script. Note that only attributes annotated with @Whitelisted are visible to be accessed in pipeline script.


If you use declarative pipeline you can use script section.

SVN Limitation

Svn based jobs have a limitation, to get last changes from latest tag you need to checkout the entire project repository otherwise the plugin will not find last tag. This is due to the way SVN handle tags.


An easy way to test this plugin is using a docker container, here are the steps (assumming you have docker installed):

  1. Run the image:docker run -it -p 8080:8080 rmpestano/jenkins-last-changes
  2. Access localhot:8080/ and create a job
  3. Configure this svn repository: https://subversion.assembla.com/svn/cucumber-json-files/trunk/
  4. Add the Publish last changes post build action;
  5. Just run the job

Job output should look like:
