Camel: Unresolved dependency exception for Camel Component

I am creating a Maven based Camel Component. I have added relevant dependencies in POM.xml but still I get below exception:
Unresolved dependency: (&(component=FileFormatConversion)(objectClass=org.apache.camel.spi.ComponentResolver))
I was able to build & run the Maven project. My component jar is however present in the component Folder:
Component Folder
Can anyone advise if there is some issue with my POM or the reason behind this exception. Here is my POM.

What is this?
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-component</artifactId>
<version>1.4.0</version>
</dependency>
That does not look correct as its some old stuff from Camel 1.x. You should remove that.
And you need to tell more how you run this? It seems like you use OSGi/Karaf or something. But take a look at how any of the existing components as an example to build custom components, or the Camel Maven archetype for component.

I resolved the issue myself. The Problem was in below Statement:
${import.packages}

How to run maven web application through cmd

I am a newbie in making web application development and I'm trying to make a website that plays video using embedded Tomcat and maven. I have only one static jsp file and I can run the program on intellij on localhost but I am finding extreme difficulties to run this project in cmd with the command line (mvn exec). My main goal is to run this program on a server I rented and then using the domain name I registered to access the website. Here is my pom.xml file

Add this dependency to your pom.xml
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>9090</port>
<path>/</path>
</configuration>
</plugin>
And then you can run the maven task provided by this new plugin like this
mvn tomcat7:run

#piy26
Thanks for the solution.
But it is useful when we want to test the application on local where web server is not installed.
#Karan, for local you can use above solution.
But for running the code on the server, I will suggest to run mvn clean package command and as described in your pom.xml it will build a war and this you can keep in web server directory and start the web server.
This has to be done on the server you rented. I will suggest go with AWS free tier for now.
I know this a long process and to avoid this you can use Spring Boot where no need to deploy war files web server is embeded.
Hope this helps:)

DynamoDB mapper class missing in dynamodb client

I want to use dynamodb client by declaring following artifacts in my project
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>dynamodb</artifactId>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>dynamodbmapper-v1</artifactId>
<version>1.0.0</version>
</dependency>
Both of the above jars not contain classes related to dynamodb.
But if see the artifacts downloaded by using following GAV then i see the classes in extracted jar.
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-dynamodb</artifactId>
Whats the difference between group com.amazonaws and software.amazon.awssdk and where is there a difference?
Why is the mapper missing in the first GAV.
Amazon mentions following in the first artifact
<artifactId>dynamodbmapper-v1</artifactId>
<name>AWS Java SDK :: Test :: Amazon DynamoDB Mapper v1</name>
<description>DynamoDB Mapper largely unchanged from v1. The v1 Mapper is kept for testing purposes only. All classes are in the test directories to prevent use in application code.</description>
<url>https://aws.amazon.com/sdkforjava</url>

Personally I don't like the amazon documentation - I'm not sure if this is your case but, for me, most of the time the material there is outdated.
I'm using the aws client and the Lavelle community dynamo library to make some queries into DynamoDB via annotations / querydsl.
Below follows my pom.xml for a spring-boot/spring-data/dynamodb/swagger micro service.
I hope it helps.

Compilation failure child package does not exist

I am trying to create simple Rest API app and I want to check it with jbehave framework, everything worked fine until I added dependency for image_capture project in my service_tests project.
In my code everything fine, my service_tests recognize image_capture classes but when I am trying to mvn clean install for parent app I am getting
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project service_tests: Compilation failure: Compilation failure:
for all packages from my image_capture project.
I am using IntelliJ, java 8 and spring boot for Rest API app.
I saw many answers from stackoverflow and did not succeed with one of them.
Thanks for help in advance.

I found a reason: Spring Boot classes is not accessible via dependencies as I understood. That a reason that my test app does not see spring boot classes while compiling via Maven. The solution is to use additional app, not spring boot app, that has class that represents spring boot Entity class.
I found some reference in this article: https://www.toptal.com/spring/top-10-most-common-spring-framework-mistakes
The solution that I used here is a Common Mistake number 2 from the article.

The method neo4jServer in the file DatabaseConfiguration.java of type DatabaseConfiguration must override or implement a supertype."

I want to develop a java application on top of a Neo4j graph database.
For this application I want to reuse the boiler plate code from Mr. Vlastaridis on Github via https://github.com/jhipster/jhipster-neo4j-app/tree/2a6fa89f8c8aa13dc7ea7856b4ee521efceeb7c7
This Neo4j example is developed for the old 2.xx version of Neo4j. I want to update the database to version 3.xx. Therefore I have to update the Spring Data Neo4j project implementation in this application.
I have therefore modified the necessary entries in the POM.XML file. I used the properties and dependencies of https://github.com/neo4j-examples/movies-java-spring-data-neo4j-4 as an example for the modifications in my POM.XML file.
To my knowledge this top POM.XML implementation should result using Spring Boot into an inclusion of all other dependancies including the necessary Spring Data Neo4j dependencies. This seems not to be the case however.
As a result of the modified POM.XML I end up with an error in Eclipse and Maven: "The method neo4jServer in the file DatabaseConfiguration.java of type DatabaseConfiguration must override or implement a supertype."
Question: how do I modify the POM.XML in the boiler plate code in order to remove the error message?
The implementation of DatabaseConfiguration.java looks like this:
package com.mycompany.myapp.config;
import org.neo4j.ogm.session.Session;
import org.neo4j.ogm.session.SessionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.repository.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.server.Neo4jServer;
import org.springframework.data.neo4j.server.RemoteServer;
import org.springframework.data.repository.query.QueryLookupStrategy;
#Configuration
#Profile("!test")
#EnableNeo4jRepositories(basePackages = "com.mycompany.myapp.repository", queryLookupStrategy = QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND)
public class DatabaseConfiguration extends Neo4jConfiguration {
private final Logger log = LoggerFactory.getLogger(DatabaseConfiguration.class);
#Override
#Bean
public Neo4jServer neo4jServer() {
log.info("Initialising server connection");
return new RemoteServer("http://localhost:7474", "neo4j", "1234");
}
#Override
#Bean
public SessionFactory getSessionFactory() {
log.info("Initialising Session Factory");
return new SessionFactory("com.mycompany.myapp.domain");
}
#Override
#Bean
public Session getSession() throws Exception {
log.info("Initialising session-scoped Session Bean");
return super.getSession();
}
}
My POM.XML file looked like this. Due to the limitations of Stackoverflow I removed most of the non-Neo4j related properties and dependencies in this POM.XML.

You are using spring-data-neo4j in version 4.1.1.RELEASE. In your DatabaseConfiguration class you are extending Neo4jConfiguration. Your problem is, like the error says, you want to override a method which is not existing in the superclass. In version 4.1.1.RELEASE of SDN there is no method called neo4jServer what you can override (This method was removed something about 4.1.0.RELEASE)
So what you can do is to change your configuration suitable on the SDN version you are using - remove the neo4jServer method and use a configuration like this:
#Bean
public SessionFactory getSessionFactory() {
return new SessionFactory(getConfiguration(), "com.mycompany.myapp");
}
#Bean
public Neo4jOperations neo4jTemplate() throws Exception {
return new Neo4jTemplate(getSession());
}
#Bean
public org.neo4j.ogm.config.Configuration getConfiguration() {
org.neo4j.ogm.config.Configuration config = new org.neo4j.ogm.config.Configuration();
config.driverConfiguration().setDriverClassName("org.neo4j.ogm.drivers.http.driver.HttpDriver")
.setURI("http://localhost:7474")
.setCredentials("neo4j", "1234");
return config;
}
#Bean
#Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return super.getSession();
}
Another option (what i would not recommend) is to change the version of SDN in your pom.xml to
<spring-data-neo4j.version>4.0.0.RELEASE</spring-data-neo4j.version>
