Here I am basically looking for a dependency parameter.
Let's say I have two dropdowns in the build parameter section. Based on the value selected from the first dropdown the possible default I want the values of the second dropdown to vary.
Is there any plugin or approach to handle this requirement effectively?
This is exactly what you are looking for: https://github.com/biouno/uno-choice-plugin/wiki/Uno-Choice-Cascade-Dynamic-Choice-Parameter
It seems to be a hidden gem, haven't found it in any of the similar questions so far.
I have not used it, but it looks like the following plugin may do what you want:
A Jenkins parameter plugin that allows for two select elements. The second select populates values depending upon the selection made for the first select.
A new plugin with this capability (and much more) is available here: https://wiki.jenkins-ci.org/display/JENKINS/Active+Choices+Plugin
The wiki page contains several usage examples and code
This is what you want to achieve right?
Then you could inherit hudson.model.ChoiceParameterDefinition, and override its method of getChoicesText. return the options based on whatever you want, in your situation, you could get environments from Hudson.getInstance().
Below snippets is shown how get environment variable.
Hudson.getInstance().getGlobalNodeProperties()
.get(EnvironmentVariablesNodeProperty.class).getEnvVars().get(name);
Here is the similar question.
This should do the trick it lets you to single select, multiselect and do it in levels https://wiki.jenkins-ci.org/display/JENKINS/Active+Choices+Plugin
Here is the example, I'd like to find when I was looking for this question ;
Here is the way to create an active choice reactive parameter with Jenkins job DSL.
activeChoiceReactiveParam('PARAMETER_NAME') {
description('Parameter description')
filterable()
choiceType('SINGLE_SELECT')
groovyScript {
script('return [ANOTHER_PARAMETER + ".suffix", ANOTHER_PARAMETER + ".suffix2"]')
fallbackScript('return ["NotFound"]')
}
referencedParameter('ANOTHER_PARAMETER')
}
Note: if it doesn't work by importing job via DSL, just "Configure" and "Save". There is a bug: JENKINS-42655
