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"

I am trying to create a Jenkins job that has dependent parameters.
Firstly I want to be able to choose a main parameter:
And then secondly to be able to choose from a set of options that are dependent parameters of the main parameter.
If I select a different main parameter:
I then want to have a different set of options as the dependencies to the second main parameter.
Please, can you help me with how I can achieve this?
I would suggest the Active Choices plugin (also known as "uno-choice"). (This question has references to both, though they're not the accepted answer.)
For your specific use case, you'll want to add two parameters to your job:
Active Choices Parameter
Name: MainOption
Script: Groovy Script
return ['A','B']
Active Choices Reactive Parameter
Name: DependentOption
Script: Groovy Script
def choices
switch(MainOption){
case 'A':
choices = ['Blue','Green','Yellow']
break
case 'B':
choices = ['Black','White','Grey']
break
default:
choices = ['N/A']
break
}
return choices
Fallback Script: Groovy Script
return ['Option error']
Referenced parameters:
MainOption
The "Referenced parameters" setting is the key - when that value is changed, the plugin will re-evaluate the Groovy script, giving you the dependent parameter effect.
For all of you who stumble upon the same kind of problem (like I did). There is a fairly new Jenkins plugin available that does exactly what is desired here: display a dependent set of drop-downs, updating dependent boxes when a main box changes selection.
For your job you just need to follow the following steps:
Install "Multiselect Parameter Plugin"
The "multiselect parameter plugin" can be installed from Jenkins plugin management, the documentation is available on its Jenkins Plugin page.
Add new parameter
Use "Multiselect Parameter" type
Set name to a sensible value
give a short description
configure like shown below:
H,Main option,Dependent option
V,SELECTED_MAIN,SELECTED_DEPENDENT
C,A,Blue
C,A,Green
C,A,Yellow
C,B,Black
C,B,White
C,B,Grey
Use selected values
When you run "build with parameters" in your job, the following boxes are displayed for selection:
In your build script you can simply use the configured environment variables SELECTED_MAIN and SELECTED_DEPENDENT, which contain the selected values from both select boxes.
I am using parameterized build in Jenkins? Is there a way when changing the values of parameters (String parameters for example) to save them for next build instead of using the default?
You can use Extended choise parameter plugin and set default value source to file as described in another question.
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 am setting up a parameterized build on my Jenkins server.
Basically I want to have the git branch name as a parameter. Then I want to use that parameter in various other fields in the job config.
I don't know if this is even possible, but I hope that it might be as it seems an obvious need.
The only docs I could find is this old wiki page
https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Build
It shows that build parameter is available as an ENV var, but it doesn't show how to use it elsewhere in the job config.
despite being undocumented, this syntax works in job config fields
${PARAM_NAME}
Just use $PARAM_NAME anywhere in the configure.
The easiest way is to use the "Git parameter" parameter type in your config and then you can reference that simply in the Source Code Management section - see here. This assumes that the Jenkins instance has the Git parameter plugin installed.
If you don't have that option, then:
you can simply add a String parameter to the configuration and use that in you configuration, but you need to uncheck "Lightweight checkout" to avoid errors like this:
stderr: fatal: Couldn't find remote ref refs/heads/${BRANCH}
String parameter declaration:
String parameter usage:

I have been using Jenkins for a few weeks and I have one small problem. I can't find any plugin or solution for storing the last value of a parameter in a parametrized job as a default value for the next build.
For example:
My parameter takes build version (1.0.0.01) in the first build. In the next build it will be changed to 1.0.0.02, but I want to have a 1.0.0.01 in the default value field as a hint.
Does anybody have a solution or advice?
The Persistent Parameter Plugin is exactly what you are looking for!
You just need to download it from the official Jenkins repository and install it, no need for any additional setup.
Then on your job, you just need to add a "Persistent Parameter" in order to have default values used and saved between builds.
You can add a System groovy build step to your job (or maybe a post build Groovy step) using the Jenkins API to directly modify the project setting the default parameter value.
Here is some code that may be useful to get you started:
import hudson.model.*
paramsDef = build.getParent().getProperty(ParametersDefinitionProperty.class)
if (paramsDef) {
paramsDef.parameterDefinitions.each{ param ->
if (param.name == 'FOO') {
println("Changing parameter ${param.name} default value was '${param.defaultValue}' to '${param.defaultValue} BAR'")
param.defaultValue = "${param.defaultValue} BAR"
}
}
}
Have a look at the class ParameterDefinition in the Jenkins model.
You probably need to modify the default param value based on the current build executing. Some code to get that would look like this:
def thisBuildParamValue = build.buildVariableResolver.resolve('FOO')
The Extended Choice Parameter plugin provides this capability by using default parameter values from a properties file. A default parameter can be selected from a specified property key and this key can be programmatically modified in your current build. I would then use a groovy script in the current build to set the value of the default property key for the next build.
As an example you would have an Extended Choice Parameter whose default value is defined by a properties file version.properties with keys as follows:
versions=1.0.0.02, 1.0.0.01, 1.0.0.00
default.version=1.0.0.02
The parameter definition would include:
Property File=version.properties
Property Key=versions
Default Property File=version.properties
Default Property Key=default.versions
The GUI for your parameter in the next build would show a selection list with 1.0.0.02 selected by default. This feature is also very useful for pipeline builds where you would want the parameters of a downstream build stage to be set by an earlier build.
The only drawback to this approach might be that the parameter UI will be a drop-down selection. You may opt to have a single value in the versions property key so not to confuse your users.
Similar to thiagolr's answer, but for those of you using pipelines! It appears the persistent-parameter-plugin doesn't work for those using pipeline 2.0. But there is a patched version at https://github.com/ashu16815/persistent-parameter-plugin which seems to work for me.
Clone it locally:
git clone https://github.com/ashu16815/persistent-parameter-plugin.git
Build it:
mvn clean install
Install it in Jenkins:
1) Navigate to Jenkins > Manage Jenkins > Manage Plugins
2) Click Advanced tab
3) Scroll down to Upload Plugin
4) Click Choose file and select the persistent-parameter.hpi in the target directory of the maven build above
Now it should persist.
