How do pipeline parameters and jenkins GUI parameters work together?

Question

I am using a pipeline in a jenkinsfile and I am not sure how to properly link the job in Jenkins and the pipeline.

I defined parameters in my jenkinsfile (some with def

This problem can be solved by adding a special parameter to avoid default values being override. Here is the sample code.

if (!params.__INIT__) { // this value will be true once parameters get initialized
    properties([ parameters([
            string(name: 'SOURCE_URL', trim: true),
            string(name: 'TARGET_URL', trim: true),

            string(name: 'DEPLOY_URL', trim: true),
            credentials(name: 'DEPLOY_KEY', required: true ),

            string(name: 'BUILD_NODE', trim: true),

            booleanParam(name: '__INIT__', defaultValue: true, description: "Uncheck this field in configuration page and run this job once if you want to re init parameter."),
    ]) ])
    return // exit 
}

// Your task stars from here

By doing this way, the parameters won't be initialized again next time because __INIT__ has been set to true. On the other hand, if you update your script and change some parameters, you can just run the job by unchecking the __INIT__ field.
