Creating freestyle project from groovy script

Question

Is it possible to create new freestyle project and add it to the dashboard view on Jenkins straight from the groovy script?

For example, I want to go through the list of all dependencies for a project. If a dependency is missing from the project list I want to fetch it, create freestyle project and then run the build.

I think this might be what you need:

    @NonCPS
    def createFreestyleProject(String projectName){
        def parent = Jenkins.getInstance()
        //Instantiate a new project
        def project = new FreeStyleProject(parent, projectName);

        //Set a description for the project
        project.setDescription("Just a placeholder for a description")

        //Create a parameter for the project
        def parameterDefinitions = new ArrayList<ParameterDefinition>();
        def name = "ParameterOne"
        def defaultValue = "1"
        def description = "Just a placeholder for a parameter description"
        parameterDefinitions.add(new StringParameterDefinition(name, defaultValue, description))

        //Create a job property for the project
        def jobProperty = new ParametersDefinitionProperty(parameterDefinitions)

        //Adding and saving the job property to the project
        project.addProperty(jobProperty)
        project.save()
        parent.reload()
    }

But before this you must do:

    import com.cloudbees.groovy.cps.NonCPS
    import hudson.model.FreeStyleProject
