I need to include my release notes in a gradle variable.
How to get changelog since last build in Jenkins, so that I can use them in my gradle variable
Below line in content section of Editable Email Notification will give the output of changes from the last build and changes from last successful build.
${CHANGES}
${CHANGES_SINCE_LAST_SUCCESS}

I have installed the Changes Since Last Success Plugin for Jenkins jobs. Inside the Build step of a Jenkins job I am trying to echo the value of the CHANGES_SINCE_LAST_SUCCESS variable. Unfortunately there is no value for this variable. I echo this value into a file inside my job's workspace.
You need Email-ext plugin instead.
Changes Since Last Success plugin has nothing to do with the CHANGES_SINCE_LAST_SUCCESS variable.

This plugin adds a build action to aggregate changes from all previous builds to the last successful one. The primary goal is to generate a changelog to be used for continuous delivery, as an aggregate for all changes since the last deployable artifact.
Additionally, this plugin can be used to generate a changelog for an arbitrary range of builds:...
In our Jenkins job, we need to sent an email containing a url in a post-build step (we also post the url to a Slack channel, but that's just about the same thing). The value of the url is dependent on the result of the build. Modification to an environment variable doesn't persist across build step. Writing the url to a file in one step and reading it in another is not an option either since the email/slack plugin has no ability of shell script execution. As a result, we've been using build parameter to solve this issue and the set-build-parameter command of jenkins-cli works fine.
After a recent upgrade of Jenkins (we're now at 2.75), set-build-parameter fails to work anymore. It reports the following error:
ERROR: Failed to identify the build being executed
According to Jenkins-cli's help command, set-build-parameter seems to be deprecated:
set-build-parameter
Update/set the build parameter of the current build in progress. [deprecated]
So, what's the correct way to modify the value of a build parameter across build steps in the latest version of Jenkins?
I frequently manipulate build parameters in shell script blocks, you have to edit them, save them in a file f. e.:
buildParamter=true>variable.txt
Now you can use the envInject Plugin and reference the the newly created file.
My requirement is to get the perforce change-list details from the last successful build to the latest successful build.
For Eg: I have Jenkins builds like below
JOB1:build#112 - Successful
JOB1:build#113 - Failed
JOB1:build#114 - Failed
JOB1:build#115 - Successful
I want Jenkins to show all p4 change-list in the build#115 that went in for build#113 and build#114 . Jenkins always show the p4 change-list between the last two build regardless of failure or successful build. I need this to generate the report that the particular successful build has these many p4 check-ins.
I am assuming from change-list you mean to say diff of configs between two successive build's.
For this we have JobConfigHistoryPlugin
where you can see all the config changes in GUI and can revert to any previous build config.
Hope it helps.
Edit:
Did you try PerforcePlugin or P4Plugin ?
There is one jenkins plugin which solved my query.

Is there a way to change the build number that is sent via email after a job completes? The problem is that are product builds are NOT being done by Jenkins, so we want to be able to get the build number(ie. from a text file) and update the build number in Jenkins to match it. I have tried to set the build number:
set BUILD_NUMBER=45
But the email is still showing the build number that Jenkins originally set.
If you have access to the script console (Manage Jenkins -> Script Console), then you can do this following:
Jenkins.instance.getItemByFullName("YourJobName").updateNextBuildNumber(45)
can be done with the plugin:
https://wiki.jenkins-ci.org/display/JENKINS/Next+Build+Number+Plugin
more info:
http://www.alexlea.me/2010/10/howto-set-hudson-next-build-number.html
if you don't like the plugin:
If you want to change build number via nextBuildNumber file you should
"Reload Configuration from Disk" from "Manage Jenkins" page.
Under the job workspace folder, like:
C:\Program Files (x86)\Jenkins\jobs\job_name
there is a file named nextBuildNumber.
Setting the build number in the file and reloading the configuration from disk (Manage Jenkins menu) will force the next build you start to have the value from the file as BUILD_NUMBER.
If you have branch name including Forward Slash (using git flow for example), you will need to replace the Forward Slash with its Unicode character %2F within the branch name.
Here is an example for the pipeline My-Pipeline-Name and the branch release/my-release-branch-name
Jenkins.instance.getItemByFullName("My-Pipeline-Name/release%2Fmy-release-branch-name").updateNextBuildNumber(BUILD_NUMBER)
I was able to find out about this by running the following command which will list the different jobs (branches) for your pipeline
Jenkins.instance.getItem("My-Pipeline-Name").getAllJobs()
Hope it helps.
Perhaps a combination of these plugins may come in handy:
Parametrized build plugin - define some variable which holds your build number
Version number plugin - use the variable to change the build number
Build name setter plugin - use the variable to change the build number
You can change build number by updating file ${JENKINS_HOME}/jobs/job_name/nextBuildNumber on Jenkins server.
You can also install plugin Next Build Number plugin to change build number using CLI or UI
For multibranch pipeline projects, do this in the script console:
def project = Jenkins.instance.getItemByFullName("YourMultibranchPipelineProjectName")
project.getAllJobs().each{ item ->
if(item.name == 'jobName'){ // master, develop, feature/......
item.updateNextBuildNumber(#Number);
item.saveNextBuildNumber();
println('new build: ' + item.getNextBuildNumber())
}
}
Follow the steps: Jenkins Console > Manage Jenkins > Script Console, then write the script as:
Jenkins.instance.getItemByFullName("Your_job_name").updateNextBuildNumber(45)
By using environmental variables:
$BUILD_NUMBER =4
I have problem in configure jenkins to auto build and deploy java project. I want to build and deploy once a day. However this build only there are changes during the day. IF there is no changes, I don't want jenkins to auto build and deploy.
Note: that I used gitlab as source code management.
Can you help me with this configuration.?
Firstly, you should configure the Git SCM section at the top of the job config page to point to your GitLab repository.
Then you can use the built-in "Poll SCM" build trigger — this will periodically check whether your source code repository has changed — and if it has, a build of this job will be started.
If the repository has not changed since the last build, then no build will be started.
You can configure this trigger — whether using a cron-like syntax, or a shortcut like #daily or #midnight — so that Jenkins only checks the source repository once a day.
Additionally, you should make sure that the "ignore post-commit hooks" option is enabled. If you're using webhooks from your Git repository to start Jenkins jobs whenever a commit occurs, this option prevents your once-per-day job from being triggered for every Git commit.
Here's the detail document: "Jenkins CI integration"
http://doc.gitlab.com/ee/integration/jenkins.html
Update to match your comment.
You don't want to trigger the Jenkins build via webhook. It's ok.
You want to check the code change 1 time a day.
Example on Linux, build at 6:00 AM if there's any code change.
