I am trying to Read Parmeters in jenkins job. I have set String Parameter for Job as follows.
but when I am tring to read this parameter in windows batch command as
it wont read it's value but simply return variable name only as follows
I have also installed parameterized trigger plugin.
Is there any additional plugin I need to install?
Kindly suggest
In Windows, it's %NODENUMBER% (or when using delayed expansion: !NODENUMBER!)
In *nix, it's $NODENUMBER or ${NODENUMBER} (curly brackets are only required when there is ambiguity with adjacent words, but are a good habit anyways)

I'm new to Jenkins so this is probably an easy one. I have the Extended Choice Parameter plugin installed. I'm using the Multi Select parameter type to pick from a list of servers (SERVER1,SERVER2,SERVER3) I've set Source for Value, Default Value, and Value Description.
I save it, and it looks great. I can pick any or all servers for the build. Now for the big question.. how do I use these values in the build? Basically I have a step in the build that can take in a comma separated list that is called by a shell command:
d:\python\deploy.py?serverlist=$blah
What do I put in for $blah to use that list of servers?
Just to be clear, if I'm on command line I would do the following:
d:\python\deploy.py?serverlist=SERVER1,SERVER2,SERVER3
I'm sure it's something simple but I just cannot find it in the docs or an example.
We could get the servers list like this
d:\python\deploy.py?serverlist=$SERVERLIST
or this on Windows
d:\python\deploy.py?serverlist=%SERVERLIST%
To see the list of environment variables which we could you, try this URL (change localhost by your Jenkins URL, TEST by the job name, 10 by the build number)
https://localhost:8080/job/TEST/10/injectedEnvVars/
UPDATE to #sniperd's edition:
This URL will shows us the parameters list in the Job:
http://localhost:8080/job/TEST/59/parameters/
I am having troubles to force Jenkins job to always run with default parameter. Does anyone know the possible plugin to help with that case? Right now I am using extended parameter choice, but still there is no option to just run the job with default value without asking user for parameter.
Solution 1
Currently there is not a straight forward solution to run a parameterized job with default parameter using a plugin. However there is a workaround to accomplish that using the EnvInject Plugin.
As #General_Code noted:
Just add the build step, set the variable like: var1=value and then
use it using ${var1}
Solution 2
As #RejeeshChandran noted:
a more robust solution is the Parameterized Build Plugin which provides the functionality of defaults values for the parameters.
Note
Note that Parameter Defaults Options is a plugin under development which will solve exactly this request. When it is released, you will be able to set it up so your parameter will get a default value when you run it manually.
you can use this plugin Parameterized Scheduler
allow you to write a cron expression with the parameters inside like this
H(0-29)/10 * * * * % name=value; othername=othervalue
Documentations
Use This build is parameterized option in Jenkins configuration. Here you can add default values to the parameters. It will run with default value if the user doesn't change it. It is good to have configurable parameter before running the job.
For configuration details see https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Build. You can have multiple parameters.
Go to your jenkins job -> Configure -> General Tab
Add all options in "Description" but the default option in "Default Value"
enter image description here
The maven release plugin in Jenkins prompts you for input when doing a release:prepare. It'll give you a suggested value, but you also have the choice to override that suggested value to put your own value. How can you do this same thing when writing a Jenkins pipeline in groovy? The only thing that I've found online is -> https://gist.github.com/cyrille-leclerc/552e3103139557e0196a. This method is strictly command and just gives batch mode with no user interaction.
The parameter definitions passed to the input step can specify default values. Try it in Snippet Generator.
I need to know if there is a plugin of some sort that you can select a node from a jenkins job and use that node name as a parameter to be passed to a Windows batch command
I have played with the Configuration Matrix using an Elastic-Axis or Slaves (Screenshot below where you can tick the names) plugins
But these all go and execute the Windows batch command on that selected node.
I don't want to execute it on that server but rather on the main node and only pass the value of the slave/label to the windows batch command.
I were able to do it as described here but that involves 2 jobs and a groovy scripts to interrogate the slaves/nodes config. Write it to a properties file and pass the properties file to the next job.
Jenkins: How to get node name from label to use as a parameter
I need to do about 30 jobs of these and hence would like to try to do all in one job - if I used my solution in the link above, 30 jobs would double in 60 jobs and maintenance would be kind of a nightmare.
I also would not like to have a string parameter and hard code the name of the slave/node as that will not ensure the use of only the available slaves/nodes but any server name can be entered and that would can be a problem where someone can mistype a server name for example pointing to a Production server instead of a test server.
https://wiki.jenkins-ci.org/display/JENKINS/NodeLabel+Parameter+Plugin
After installing this plugin you will have an option to add a Node parameter to Jenkins job. It will have a list of all slaves available on current master.
You can use the active choice parameter plugin
https://plugins.jenkins.io/uno-choice/
with a little groovy script to list node names in a parameter selection box.
I want to pass a version label like master.104.a1b2c3d down to a triggered build. Using ${GIT_BRANCH} in its default shape I get origin/master instead of master, which I don't want. The Token Macro plugin suggests I should be able to add parameters (and the code suggests a fullName parameter exists) so I need to be able to apply these parameters to manipulate the output.
Expected:
target=c42cccac2cc…
versionLabel=master.104.c42ccca
Observed:
target=c42cccac2cc…
versionLabel=${GIT_BRANCH,fullName=false}.104.${GIT_REVISION,length=7}
Perhaps I'm using the parameters incorrectly? Even the example from the documentation doesn't work here, but any expansion without parameters goes just fine.
The additional parameters won't work everywhere in jenkins config. See JENKINS-25465 for details.
