Getting NoClassDefFoundError while running my Cucumber Automation

I am facing the following issue while running my automation. This is what I am getting on the console.

Hi I had the same problem when cucumber 7 came out, and just today I was able to solve it, basically what I did was to update the versions of some other frameworks that might be affected by the cucumber version as well (on my pom.xml file). These are the frameworks that I use in the stable version:

I hope this helps to solve your problem, best regards!

Ahh, this is a tricky one. From the 'PluginFactory' stacktrace, I guess its caused by this:
You have a class which contains step bindings ("Given I login" for example).
To create that class you require specflow to Inject some class into the constructor (dependancy injection). If THAT class is in another project, but the StepAssembly (see specflow.json or app.config) or project reference is not correct this can happen.
See code example (C# unfortunatly, but the point should be clear)
[Binding]
public class Test{
public Test(ThisClassNotInAssembly getMe){
getMe.SomeFunction();
}
}
Other option is that a step requires a transform (from string to MyNotDependancy class). Where again, the class is in another project and at runtime the dependancy fails.

To find out which class was loaded (and which was not, respectively), run Java in verbose mode but limited to classloading like so:
java -verbose:class ...
From that output you should be able to decide which exact class was missing. If again you are looking at GeneratedMessageV3, try to look at the source code of that class. It may be that some static initializer is throwing an exception that simply told the JVM that this class could not be loaded successfully.

Quarkus with Camel call external endpoint. Error: Map at least one servlet to a path using quarkus.camel.servlet.url-patterns

I'm trying to implement a Camel to supply microservices applications, I want to call a HTTP route with my own headers with token, alias & etc. firstly I want to call an external endpoint like "http://outside.endpoint.com" and recive the JSON Response to treat the object internally.

My route that there are the camel-rest call to execute the getCompanies bean:
package com.example.control;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.Response;
#ApplicationScoped
public class CompanyRouter extends RouteBuilder {
#Override
public void configure() {
restConfiguration().component("restlet")
.host("localhost").port("8056")
.bindingMode(RestBindingMode.auto);;
rest("/api/people")
// HTTP: GET /api
.get()
.outType(Response.class)
.to("bean:getCompaniesBean"); // This will invoke the bean
}
}
my bean to call the method listCompanies:
package com.example.control;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.Response;
#ApplicationScoped
public class GetCompaniesBean {
public Response listCompanies() {
return Response.ok("Joinha!").build();
}
}

If you are going to use the default CamelHttpTransportServlet, then you can supply a minimal configuration and just set quarkus.camel.servlet.url-patterns. For example:
quarkus.camel.servlet.url-patterns = /services/*
There's more information in the documenation here:
https://camel.apache.org/camel-quarkus/latest/reference/extensions/servlet.html#_additional_camel_quarkus_configuration
Unless you really need use servlets, it's probably better & simpler to use the platform-http component as your HTTP consumer:
https://camel.apache.org/camel-quarkus/latest/reference/extensions/platform-http.html

SingletonEhCacheRegionFactory is no longer available when upgrading from Hibernate 5.2 to 5.3

A project I work on is currently using Hibernate version 5.2.15.Final. When configuring the second-level cache, the project has been using org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory as the value for hibernate.cache.region.factory_class.
When I change the Hibernate version to 5.3.12.Final, SingletonEhCacheRegionFactory is no longer in that package. A class with that same name is available in the net.sf.ehcache.hibernate package, and I can use that with no compilation errors. But if I run it I get an error when it tries to build a session:
org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.cache.spi.RegionFactory]

If I dig deeper into the stack trace, the real error seems to be this:

Here's what my pom.xml dependencies look like:

Okay, I think I figured out the problem. Previously my code had been fetching the full class name and path by doing:
SingletonEhCacheRegionFactory.class.getCanonicalName()
But in Hibernate 5.3 the class had been moved to an internal package, which is why I could no longer find it. If I used a hardcoded string with the old package name ("org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"), I no longer get that exception.

Please help!! How can I find a bug?

It seems that you have multiple asm dependencies in your project. You can find them by executing mvn dependency:tree from root project, or by looking into artifact after project build.
For using with CXF 3.x you should have dependency org.ow2.asm:asm:jar:5.x.x and greater.
Hope that helps.
