How to create ready api file through power shell script

What do you mean by "convert that into ready api XML File"?

Is that readyapi project to be created automatically and import the yaml file? or just an update?

While it is possible to generate the readyapi project automatically, that isn't just enough i.e., the test cases are required, right?

I mean how are you going to use that project without test cases?

Regarding the project creation, should be able to find some  sample online or use Javadoc for referring to API

nmrao  can you please help me get some snippet for converting yaml into soap ui from command line ? I tried my best but i couldnt get one. Any help would be greatly appreciated

You can try below sample java to generate the soap ui project. follow the comments inline.

import com.eviware.soapui.impl.WsdlProject;
import com.eviware.soapui.impl.wsdl.support.wsdl.WsdlImporter;


public class SoapUIProjectCreator {

    public static void main(String[] args) {
        // Specify the path to your SoapUI project file
        String projectFilePath = "/path/to/your/project.xml";

        // Specify the path to your YAML file
        String yamlFilePath = "/path/to/your/file.yaml";

        // Create a new SoapUI project
        WsdlProject project = new WsdlProject();

        try {
            // Import the YAML file
            WsdlImporter.importWsdl(project, yamlFilePath);

            // Save the project to a file
            project.saveAs(projectFilePath);
            System.out.println("Project created and YAML file imported successfully!");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Thank you for your response. I am trying this option achieve through CLI. Basically from Azure pipeline. is there something we can do through script?

Sure. You need to compile the java and create a jar file.

Then you can invoke thru java command using that jar file.
