ClassNotFoundException while indexing data into elasticsearch org.elasticsearch.common.CheckedConsumer

I am using below stack to index a data into Elasticsearch:
Elasticsearch 7.15.1
Apache Camel 3.12.0
Spring 5.3.12
Spring Boot 2.5.6
While indexing the data into Elasticsearch [7.15.1] I am getting ClassNotFoundException: org.elasticsearch.common.CheckedConsumer
please have a look on the detailed error below:

I tried to lower the versions of all the above mentioned stack, but no luck.
Could you please help me to resolve the issue?

Spring Boot Integration Testing

I have been trying to write a integration test for a small Spring boot Project that I have written but for some reason seem unable to get integration tests to work. Here is what I am trying to do:
package au.azzmosphere.integration;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest(classes = {IntegrationTestConfiguration.class})
public class TestIntegration1 {
#Test
public void testDummy() {
}
}
the configuration class has the following:
package au.azzmosphere.integration;
import au.azzmosphere.configuration.RobotAppConfig;
import org.springframework.context.annotation.Configuration;
#Configuration
public class IntegrationTestConfiguration extends RobotAppConfig {
}
The code is consistently getting the following errors when I try to run the Integration Test from IntelliJ
14:54:01.537 [main] DEBUG org.springframework.test.context.junit4.SpringJUnit4ClassRunner - SpringJUnit4ClassRunner constructor called with [class au.azzmosphere.integration.TestIntegration1].

Worked it out, :) The problem was that I did not have any TransactionDefinition defined because I didn't use it. The default SpringBoot annotation attempts to inject it. The answer was to use #TestExecutionListeners({DependencyInjectionTestExecutionListener.class}) which overrides the defaults and gets things going.

ApplicationContext fails to Autowire in unit Test

I'm writing a test for my #Configuration class and it crashes when autowiring the ApplicationContext. There is only one Config class in the package. The beans work in a normal execution, oddly.
Here's the basis of the test.
#RunWith(PowerMockRunner.class)
#PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = AWSConfig.class)
#TestPropertySource(properties = {""})
#DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
#PowerMockIgnore({"javax.management.*", "sun.*", "javax.net.ssl.*"})
#PrepareForTest({AWSConfig.class})
#ComponentScan(basePackages = {"com.mycompany..."})
public class AppConfigTest {
#Autowired
private ApplicationContext context;
This fails with being unable to load the context, the root cause being a class not found.

Use #ComponentScan(basePackages = {"com.mycompany.*"}) instead of #ComponentScan(basePackages = {"com.mycompany..."})
Or
simply use #ComponentScan("com.mycompany.*")

JUnit test in Spring application

I want to test a function in spring application. Here is the structure of the project
and here is the service class i want to test
public class DepartmentServiceImpl implements DepartmentService {
#Autowired
private DepartmentDao departmentDao;
//... other functions
#Override
public Department getDepartment(int depid) {
return departmentDao.getDepartment(depid);
}
}
and here is the test unit class that i made
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = "sdnext-servlet.xml")
public class TestDepartmentDetails {
Department department = new Department();
DepartmentServiceImpl service = new DepartmentServiceImpl();
#Autowired
private DepartmentDao myDao;
#Test
public void testGetDepartment(){
assertEquals("lalalalalalala", service.getDepartment(98).getDepName());
}
}
but exceptions occur which are

Your testing classes is not running in a web server. That's why you cannot find WEB-INF in CLASSPATH. You need to use an absolute file path.
Can you please try this
#ContextConfiguration("file:WebContent/WEB-INF/config/sdnext-servlet.xml")

Usually when you need to do unit testing configuration files and resource should be separate from the deployment ones. So you need to have a copy of configuration file sdnext-servlet.xml or an other one that defines the resources and database configuration for testing purposes. Put this file in the same directory of testing class directory.
In your case you only need to write database and Dao configuration.

Unable to use Weld for Context and Dependency Injection (CDI) in my stand alone Java SE application

I am trying to make a standalone Java SE application with CDI. I followed this article and I am using Weld. However when I try to instantiate Weld weld = new Weld(); I am getting the following ClassNotFound error.

I checked the weld-se JAR an it doesn't contain this Interface. What is the issue here? Thanks in advance.
Following is my Test class org.agorava.socializer.Test
public class Test {
public static void main(String[] args){
Weld w = new Weld();
WeldContainer factory = w.initialize();
OAuthLifeCycleService service = factory.instance().select(OAuthLifeCycleService.class).get();
System.out.println(service.getCurrentService());
}
}

Seems your problem is related to version "org.jboss.weld.environment.ContainerInstanceFactory" interface is available in newer version (Weld 3)
refer https://github.com/weld/core/commit/36563d252a4a2375692d7669e7a523bb6ba89136
Try updating your version of weld-se.

I had this problem while writing unit tests.
Here is the answer on github and here is the related part in my pom file:
