How to get Jenkins old build inside Jenkins - jenkins

I just tried to find out the old success full build in Jenkins, I did not find any way.
can any one help to find the old build in Jenkins ?

Jenkins has a setting where you can control for how long or how many builds you keep the build history or the build artefacts.
If you still have the build in history but you lost the artefacts you can rebuild it from the same hash. If the build definiton and the build environment (jenkins slave) is the same, you should obtain the same build result.
In this moment all the build engineering good practices that you kept will pay of.
To help you more, you need to tell us:
is it a UI (traditional) build definition, a pipeline defined in jenkins or a pipeline based on a jenkinsfile committed in the repository?
do you tag the sorce code repository (hopefully git) with the version of the build, or at least do you have in the build artefact the hash from which was built ?
do you store your build artefact in a repository so you can trace the history ? (artefactory, nexus, docker repo, GCP repo etc)

Jenkins - Copy Artifacts from upstream job built in different node

There is a job controlled by Development team which built in a different node. I am on Testing team who want to take the artifacts and deploy on test device.
I can see those Artifacts from dev are stored in some path in dev's node. Does it means it must first archived in Jenkins master before I can copy it to my job?
I am using Copy Artifact plugin and constantly getting the error
Failed to copy artifacts from <dev-job> with filter: <path-in-dev-node>
*Some newbie question since i just moved from TeamCity
You probably want to use: Copy Artifact plugin.
Adds a build step to copy artifacts from another project.
Consider also, the Jenkins post-buid step "Archive the artifacts".
If you copy from the other job's workspace, what happens if another job is in progress or the workspace is wiped? That step copies them from the node to the master and stores a copy along with the build logs, etc. That makes them available via the UI as long as the build logs remain. It can take up space tho.
If you do use archive artifacts, consider using the system property jenkins.model.Jenkins.buildsDir to store all the build logs (and artifacts) outside of the jobs config directory. Some downtime and work required to separate the two (config / logs) .
You may also want to consider using a proper repository manager (Nexus / artifactory)
Finally, you may want to learn about using a Jenkins pipeline rather the relying on chained jobs, triggers or users and so forth. Why? 'cos it's much more controlled and easier to maintain.
ps: I'm not a huge fan of artifactDeployer, but it may work for you.
pps: you may want to review this in depth answer: Jenkis downstream job fails to find upstream artifacts

How to make Jenkins multibranch pipeline keep reusing the same build node for the same branch?

Is the anyway to make a Jenkins Multibranch Pipeline better support incremental builds by preferring the last build node when it build a branch instead of choosing an available node more or less randomly?
Details:
We are setting up a Jenkins multibranch pipeline for a large Git project, where we use Make to build and test a lot of code. A full build takes 6-8 hours, but the dependency tracking in Make is good enough for us to use incremental builds, shortening most our build times a lot. For this to work, Jenkins have to pick the same workspace for changes to the same branch again. Luckily it does so - but only on the same build node.
We have some identical Jenkins slave nodes available. Each time a build job is started due to a change on a branch in Git, Jenkins apparently pick a random free build node with a fresh, clean workspace meaning no incremental build speedup.
We have tried to build via NFS, such all the build nodes can share the workspaces, but at least the NFS server we have available is way too slow to make this work.
Is there anyway to make Jenkins choose the node a little less randomly and prefer the latest node on which the branch was build the last time?

Show list of released artifactory versions for deploy build in Jenkins

I have a release build that compiles and publishes the war file to Artifactory. I'd like to have a manually run parameterized build where I can choose among the release builds that it will then pull that artifact from Artifactory and deploy it. Deployment works fine, it's the choosing I'm having trouble figuring out how to do.
Is there a straightforward way to do something like this?
The closest thing I found was Promoted Build Parameter, but this doesn't seem to give me what I need as I don't know how to translate from what it gives to the file in Artifactory.
Use one script based on Artifactory REST API to fetch the needed artifacts from artifactory server.
In jenkins job, the Choice parameter can be used.
Then in the executed shell script, you pass the parameter to the script to download the artifacts.
It works fine for us.

Avoid deploying artifact at the end of release build

I have a maven job in jenkins. Normally at the end of the build the artifacts will be deployed to artifactory via jenkins post build action.
But if I make a release build I get an error from jenkins in this case.
So, is there a possiblity to avoid deploying the artifacts at the end of a release build.
Let me precise the error. The maven goals are 'clean install'. I need the post action for deploying to artifactory by a 'normal' job. If I make a release of this artifact via the M2 Release Plugin the deploying of the relased artifacts will be done by the M2 Release Plugin itself. But at the end of the job the post action tries to deploy artifact with the old SNAPSHOT version which is not allowed by artifactory.
Jenkins M2 release plugin (used maven-release-plugin of Maven). If you have created a Maven job (instead of a Free Style), then in M2 Release section in job's configuration, you'll see the goals are:
-Dresume=false release:prepare release:perform
If you replace it with the following M2 release plugin won't call deploy goal which is initiated by release:perform goal by default.
-Dresume=false release:prepare release:perform -Darguments="-Dmaven.deploy.skip=true"
In my case, I didn't want the artifacts to go to Artifactory as soon as release:perform and release:prepare goals were completed, so the above helped. But, even though Jenkins job has a Post Build action as "Deploy to Artifactory" to either snapshot or release repositories (depending upon what kind of build you have aka automated/manually run build job OR by running Perform Maven Release ), it never called the post build action.
This can be good in the sense, now I can call deployment using the generated release artifacts in an environment and if the deployment/some IT tests are successful, then I can upload the artifacts to Artifactory. Downside is, what if your deployment depends upon fetching the new artifact from Artifactory/Nexus (i.e. somewhere in deploy script's logic) then you can't have that working until you copy artifacts from one job to another child job.
Apart from that, maven deploy goal requires valid / settings in either settings.xml or pom.xml where the you specify for each of the above sections, which are defined under section, must match with the value of section defined in setting.xml/pom.xml.
One can defined / set the value of section to use a non-release repository which is higher in order (for artifact resolution) than a snapshot repository i.e. use libs-alpha-local or libs-stage-local and then let maven deploy goal deploy the artifacts to Artifactory/Nexus.
Later, upon successful deployments to higher environments (like QA/PRE etc), you can move the artifact from alpha/stage to libs-release-local.
IS_M2RELEASEBUILD Boolean variable which comes with M2 Release plugin can be used in a conditional step to deploy here or there or not at all.
In the configuration of the 'Maven release build' you can set in the advanced mode a 'Release environment variable' (default is IS_M2RELEASEBUILD). Later in the post-bild-action 'publish artifacts' you can check if this environment variable is set and then the deploying is skipped.
I'm thinking you may want to create a separate jenkins job just for your release builds. And under post build action to run different set of maven commands just to package the artificat and not install it to the artifactory. That being said if other applications depends on that artifact you do not want to release. This may be causing versioning problems.
You should take a look at Artifactory Jenkins plugin. 1. It deploys with errors. 2. It has built in release functionality. 3. It will provide you with unique buildInfo functionality for saving build information tougher with artifacts in Artifactory, https://wiki.jenkins-ci.org/display/JENKINS/Artifactory+Plugin
If I can assume you're using the M2 Release Plugin, then there's another issue.
Skipping the deployment after a release would be an unnecessary workaround, since I've seen this work. You should try to fix this by the root cause.
It would help if you could provide more info about the error.

Do I specify binary artifact settings in the build scripts or the CI server?

I'm prototyping a new build system using Jenkins, Gradle, and Artifactory. There seems to be conflicting or rather overlapping features in these tools, in regards to specifying the build artifacts and their destination. I see three paths going forward:
Specify the artifact settings on the particular task in Jenkins, using the Jenkins Artifactory plugin.
Specify the artifact settings in the Gradle build scripts, using the Gradle Artifactory plugin.
Specify generic maven repo settings in the Gradle build scripts, using the standard Gradle "maven" plugin.
I see pro's and con's to all of these approaches, but nothing is missing a critical feature for our builds, as far as I can see.
To further my confusion, the Gradle Artifactory plugin wiki states:
Build Server Integration - When running Gradle builds in your
continuous integration build server, it is recommended to use one of
the Artifactory Plugins for Jenkins, TeamCity or Bamboo to configure
resolution and publishing to Artifactory with build-info capturing,
via your build server UI.
So, some questions to get the conversation going:
Does it make sense to clutter the build scripts with artifact logic? It might help to add that developer's don't deploy. Currently, I only see build artifacts being uploaded from the Jenkins task.
Does leaving all of this build logic in the task configuration expose us to issues, in the event that the CI server is down?
What about version control for artifact changes done through the CI interface?
I've seen simple Bamboo configurations that specify the build artifacts through the CI server UI, rather than the pom's. Is this just a bad build practice?
Is there a killer tool integration feature that separates one of these approaches from the other?
How useful is the build info object? Is that only available in the Jenkins Artifactory plugin and not the Gradle Artifactory plugin?
I am really hoping to hear from existing users of these tools and what pitfalls/requirements may have led them to one of the approaches above (or perhaps even a better one that I haven't considered yet).
Does it make sense to clutter the build scripts with artifact logic? It might help to add that developer's don't deploy. Currently, I only see build artifacts being uploaded from the Jenkins task.
I'd say that's the way to go. Your build server is the single point of truth, and only artifacts built in the build server should be deployed.
Does leaving all of this build logic in the task configuration expose us to issues, in the event that the CI server is down?
That one is simple - you shouldn't deploy while your CI server is down. Building on local machine might produce wrong artifacts, which shouldn't be deployed.
What about version control for artifact changes done through the CI interface?
Not sure I understood your question.
I've seen simple Bamboo configurations that specify the build artifacts through the CI server UI, rather than the pom's. Is this just a bad build practice?
This configuration ignores Maven's ability to deploy, and I am not sure I can find a good scenario to justify it. The only thing I can think of is deferred deploy, but Artifactory plugin can take care of that.
Is there a killer tool integration feature that separates one of these approaches from the other?
Now we got to the essence :)
Well, the advantage of defining what you deploy in your build script (in case of Gradle) gives you the flexibility to fine-tuning every aspect of the deployment (think about the dynamic properties you might want to add in certain cases). Another very serious advantage is that your build is source, which means it is versionable in your version control.
The advantage of defining the deployment details in the build server configuration is that the build server is the only place the deployment should occur. So, if you don't have the deployment details in your build script, you know for sure it won't be deployed standalone.
So, how can you combine between the two to get the advantages of both worlds?
Code your deployment logic in your Gradle script using the Artifactory plugin DSL. Provide details like username and password from properties, which exists on build server only.
How useful is the build info object?
Extremely useful. The information in buildInfo was harvested during the build process and the buidInfo is the only place it exists. Having this information is the only option you will be able to reproduce this build in the future.
Is that only available in the Jenkins Artifactory plugin and not the Gradle Artifactory plugin?
'artifactory' and 'artifactory-publish' Gradle plugins both generate the buildInfo object, regardless of where are they running (be it your local machine or Jenkins build server).
