How to Order Jenkins Parameters Using Groovy Script?

To order Jenkins parameters using a Groovy script, you can make use of the reorder method. This method allows you to rearrange the order of parameters within a Jenkins job configuration. By writing a Groovy script that calls the reorder method and specifies the desired order of parameters, you can easily customize the layout of your Jenkins job parameters. This can be particularly useful when you want to streamline the parameter input process or improve the overall organization of your Jenkins job configuration. By leveraging the power of Groovy scripting, you can achieve more flexibility and control over how parameters are displayed and accessed within your Jenkins jobs.

How to store the ordered Jenkins parameters in a file using Groovy script?

You can store the ordered Jenkins parameters in a file using a Groovy script by following these steps:

1. Create a Groovy script in your Jenkins job's workspace or any other desired location.
2. Use the getProperty method to retrieve the ordered parameters from the Jenkins job.
3. Write the parameters to a file using the FileWriter class.

Here is an example Groovy script that stores the ordered Jenkins parameters in a file:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

def parameters = []
def job = Jenkins.instance.getItemByFullName("YourJobName")

job.getLastBuild().actions.each { action ->
  if (action instanceof ParametersAction) {
    action.parameters.each { parameter ->
      if (parameter.class.canonicalName == "hudson.model.StringParameterValue") {
        parameters.add("${parameter.name}: ${parameter.value}")
      }
    }
  }
}

def outputFile = new File("ordered_parameters.txt")
outputFile << parameters.join("\n")
outputFile.close()

Replace "YourJobName" with the name of your Jenkins job. This script will store the ordered parameters in a file named ordered_parameters.txt in the same location where the script is executed.

You can run this script either as a Jenkins Pipeline script or using the Jenkins Script Console. Make sure you have the necessary permissions to run scripts in your Jenkins environment.

How to customize the ordering logic for Jenkins parameters in Groovy script?

To customize the ordering logic for Jenkins parameters in a Groovy script, you can use the parametersDefinition section in the Jenkinsfile to define the parameters with a specific order.

Here is an example of how you can customize the ordering logic for Jenkins parameters in a Groovy script:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
22

pipeline {
    agent any
    parameters {
        string(name: 'PARAM1', defaultValue: 'value1', description: 'Parameter 1')
        string(name: 'PARAM2', defaultValue: 'value2', description: 'Parameter 2')
        string(name: 'PARAM3', defaultValue: 'value3', description: 'Parameter 3')
    }
    
    stages {
        stage('Example Stage') {
            steps {
                script {
                    // Your logic here
                    echo "PARAM1: ${params.PARAM1}"
                    echo "PARAM2: ${params.PARAM2}"
                    echo "PARAM3: ${params.PARAM3}"
                }
            }
        }
    }
}

In this example, the parameters section defines the order in which the parameters will be displayed in the Jenkins build job, which can be customized by changing the order in which they are listed. You can also customize the ordering logic in the Groovy script itself by using conditionals or loops to handle the parameters in a specific order.

How to organize Jenkins parameters into categories using Groovy script?

One way to organize Jenkins parameters into categories using Groovy script is to use the Job DSL plugin. Here is an example script that demonstrates how to create a parameterized Jenkins job with multiple categories of parameters:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

job('Example Job') {
    parameters {
        choiceParam('Category 1 Parameter', ['Option 1', 'Option 2'], 'Select an option', 'Category 1')
        stringParam('Category 1 String Parameter', '', 'Enter a string', 'Category 1')
        booleanParam('Category 2 Boolean Parameter', false, 'Check to enable', 'Category 2')
    }
    
    scm {
        git('git@github.com:example/repo.git')
    }
    
    steps {
        shell('echo "Hello, World!"')
    }
}

In this script, we have defined two categories of parameters: 'Category 1' and 'Category 2'. Each parameter is assigned to a specific category using the optional category parameter of the parameter definition functions. This allows you to organize the parameters in a logical and structured way within the Jenkins job configuration.

You can further customize and extend this script to add more categories and parameters as needed for your specific use case. Additionally, you can use the Config File Provider plugin to manage parameter configurations separately and load them dynamically into the Jenkins job DSL script.
