I could successfully install the jenkins online over my laptop. But while trying to install the jenkins offline (on my office workstation which cannot be connected to internet) the hell breaks loose.
After running the jenkins.war over command line although the jenkins was successfully installed yet some of the plugins were missing.I managed to get some help from the post How to install a plugin in Jenkins manually?
But then each of the plugins have to be individually downloaded and then copied over to my offline machine. So I had a trick.
I copied all the folders under .jenkins directory (in my online installation machine) and then copied them to my offline machine. Whoa!
It worked!
But I still get one single error:
Maven Integration Plugin V2.16 .javadoc 1.0 is missing. To fix, install v1.0 or later
So is there a way/website/pdf/repository which is a one stop solution/steps to smoothly install (read has all the required dependencies as a zip) Jenkins in offline mode. (If not, to the creators of Jenkins: Would it be a good idea to have one?)
I'm also searching for an easy way to manage the dependencies between the plugins but as far as I know there is no official tool for that.
Either you have a .zip file with all the plugins which you prepare one time or you fix the errors manually.
For your problem it should be enough to install the following .hpi file: https://updates.jenkins-ci.org/latest/javadoc.hpi (javadoc has no dependencies to other plugins)
You can download the .hpi version of plugins required and paste them in plugins folder at jenkins_home and then restart the jenkins,then you can able to use those plugins.

I have an issue with deploy to container plugins v 1.15 so I have decided to remove the current version and downloaded the V1.13 manually and copied the .hpi to /var/lib/Jenkins folder and restarted the Jenkins many times and specific dependencies with specific versions installed manually all the versions look ok but deploy to container plugin not installing that I don't see any deploy folder and deploy.jpi file.
Please suggest me is there anything I missing?
Fore some reasons I have to use Jenkins 2.32 and I need to install some plugins there. Machine with it has no internet, so I only can upload plugin file to install it from file.
So, the problem is there any easy way to obtain required plugin for required Jenkins version with all it's dependencies?
p.s.
I can't update Jenkins - it's out of my power.
p.p.s.
I find only way to download old versions of plugin, but by this way I can't check dependencies and required jenkins version before loading.
I had such an environment before.
Warning: it's an annoying process.
Because there was no internet, we uploaded all plugins manually, i.e. looking at the plugin page (e.g. https://plugins.jenkins.io/git/) and then downloading from the archive (e.g. https://updates.jenkins.io/download/plugins/git) the .hpi file. As you have to use a relatively old version of Jenkins you may want to check the changelog of the plugin, if you have to use an older version.
In addition on each plugin page the dependencies are listed and you have to repeat the above steps for each dependency.
The only good thing is that usually Jenkins gives you hints, which dependencies are missing after you uploaded a plugin.
You can probably extract the information out of the plugin-versions.json in the Jenkins Update Center.
For more information about the layout of update center, see this document.

Installed Jenkins on a Linux server and want to install some plugins manually.
I want to install Blue Ocean and Artifactory.
For both plugins I downloaded the hpi file and tried to install it, but I get a lot of dependency errors.
Do I now have to install those dependencies manually as well? or is there a better way to do this?
I tried to install one of those dependency and that one also had some dependency errors as well :-(
The Linux server is not able to access the internet.
Thanks!
Robert
You are correct that BlueOcean has a lot of dependencies.
Given you are not able to connect to the internet you will need to download all 21 BlueOcean related hpi files and upload them from the Manage Jenkins > Manage Plugins > Advanced tab.
Alternatively, if you have access to the server that your Jenkins instance is running on you can copy the hpi files into the %JENKINS_HOME%/plugins folder. The corresponding directories (exploded from the hpi, which is just a zip file) will be created on Jenkins restart.
The easiest way to acquire all 21 plugin files is to open The Jenkins plugin page and search for blueocean. Download the same numbered version of all 21 and upload them one by one. Order shouldn't be an issue. As long as they are all present on restart the dependencies will resolve.
Same process goes for any other plugin. If you're able to get the machine connected to the internet it will make the process a lot simpler as you will be able to use the update center, which manages dependencies and update notifications.
Same case here. Our Jenkins is setup in OpenShift which is not allowed to connect to the Internet. Downloading a plugin 1-by-1 is tiresome. Not to mention that each plugins have its own dependencies that needs to be downloaded as well.
Here's what you would do...
Run a Jenkins locally in a machine that can download plugins.
Download and update all the plugins you want using the Update Center.
Go %JENKINS_HOME%/plugins directory. Inside this folder you would see *.jpi. These are your plugins. Its dependencies will be downloaded as well.
Rename it to *.hpi then keep it in some directory.
To test...
In your local Jenkins delete everything in %JENKINS_HOME%/plugins directory then put all *.hpi in this directory.
Restart your local Jenkins.
Verify if the plugins you require are installed and updated.
I have a machine with blocked outgoing connections so it is not possible to update jenkins nor install the plugins I need for my work.
My idea is the following: I download the jenkins .war on my personal laptop and complete the installation + the plugin download.
Then I just move this .war to the machine where I need jenkins to be up and running.
Is it possible? Where are the plugins/updated data stored?
Also, would it be a problem the fact that my laptop has windows as os, while the destination machine is a linux RHEL?
Your solution sounds crazy :D
This could be help you:
Update Jenkins war
If you have shell access with root privilege, there is a manual way.
Download latest war file inside your linux, using wget , curl or just upload it using winscp from your windows.
Stop jenkins
Backup EVERYTHING: linux snapshot, jenkins workspace, jenkins war file, etc
Replace the old war with new war
Start jenkins

Plugin
Jenkins has an option to install plugins called Manage Plugins
This offer two options :
(1) Install plugins using available option
For official and compatible plugins, suggested by Jenkins :
(2) Install plugins using upload option
For custom plugins or when is not available on official repositories:
I may need to reinstall Jenkins on a Windows Server 2008 R2 Enterprise server. If I run the installer for an already installed version, it gives me the option of uninstalling. I've already tried the "repair" option but it didn't solve my problem. If I do the uninstall, what will happen to my existing jobs and their history? Will the entire Jenkins folder be deleted? If so, will I be able to restore them from a backed up copy?
I'm not sure about Windows, but I think in linux, the jobs/configs directory can be copied across multiple Jenkins installations. Make a backup of your jenkins home directory first. The Jenkins executable itself is less critical, as it can easily be reinstalled without affecting your build environment. See this link for more information: https://wiki.jenkins-ci.org/display/JENKINS/Administering+Jenkins
Yes, you can restore them by backing up your jenkins install folder and then copying the contents back to the jenkins install folder after reinstallation. This works for linux or windows. All job info and configuration is stored on the file system.
