Develop Reference

How to load all the examples in to the #ExampleObject without specifying the ref so its visible in SwaggerUI?

I am developing a simple application where I would like to read the files from a remote URL and add them to the #ExampleObject. I am able to achieve this using CustomClass SchemaFileReader implements OASFilter but the only problem is that I need to manually specify the name of the file in the ref such as #ExampleObject(name = "Example1", ref = "Example1.json").
Since I am reading the URL there can be many files and I do not know the name of all the files so I need an approach where I can add the #ExampleObject dynamically directly without specifying ref. Rather it should read all the data from the examples. Can someone please specify some logic on how to achieve this?
I have posted my complete code on GitHub: https://github.com/Aravinda93/code-with-quarkus.
As of now, I have added manually 2 files to my #ExampleObject by specifying the ref but I need a dynamic approach to add all the 3 files present in the resourses/jsonfiles without providing the ref for all the files individually.
To run the application, please follow the following steps:
Open the terminal for the project and run mvn compile quarkus:dev
Press d in the command line this should open the Swagger-UI.
Select swagger-ui from SmallRye OpenAPI
Expand api/generate and there we will see only 2 files under examples. I need an approach to get all 3 field without specifying the ref for all of them.

After trying some things, finally, this worked for me. Posting here as it can be useful to someone in the future:
Following is my RestControllerResponse:
import org.eclipse.microprofile.openapi.annotations.media.Content;
import org.eclipse.microprofile.openapi.annotations.parameters.RequestBody;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import java.util.Map;
#Path("/api")
public class RestControllerResponse {
#Path("/generate")
#POST
#Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
#Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
#RequestBody(description = "Testing Example without ref",
content = #Content())
public String generator(final Map<String, Object> input) throws Exception {
return "Hello From Generator Method";
}
}
Following is my SchemaFileReader which has the capability to read all files and respective subfolder with files and get the file contents and add to examples, pass the required URL to the getFolderData method:

Spigot Minecraft plugin coding NoClassDefFound error mysql

When i start the server this error comes :
I am using IntelliJ Idea and MySQL jar is added to the src and in the project modules.
Error pastebin
Here is my code
package com.okaam.jaajhome;
import org.bukkit.plugin.java.JavaPlugin;
import pro.husk.mysql.MySQL;
import java.sql.Connection;
import java.sql.SQLException;
public class JaaJHome extends JavaPlugin {
static JaaJHome instance = null;
MySQL MySQL = new MySQL("address", "port", "schema", "user", "password", "");
static Connection c = null;
#Override
public void onEnable() {
System.out.println("Plugin JaaJHome active");
getCommand("sethome").setExecutor(new SetHomeExecutor());
getCommand("home").setExecutor(new HomeExecutor());
try {
c = MySQL.getConnection();
} catch (SQLException e) {
e.printStackTrace();
}
instance = this;
}
public static JaaJHome getInstance() {
return instance;
}
}

It seems like you're missing on some dependencies, make sure you have them either in the plugins folder as a non plugin or in the classpath to make sure they're loaded.

I tried all solutions over net, and all of them points out that this error is because i am missing some JAR files. But i am having all the JARs. Can someone help me with this issue?

It looks as though you are referencing both google-collections and guava. Since guava is a superset of google-collections you actually only need to reference guava. Remove the reference to google-collections and you should find the problem is resolved.
