Maven Plugin not loading application properties

I have a problem when i try to Run my own maven plugin,
I need my maven plugin to load properties file, from the module that execute this plugin.
I have a Maven project with 2 modules
Module A which I create the plugin
#Mojo(name = "Test", defaultPhase = LifecyclePhase.COMPILE)
public class Test extends AbstractMojo {
#Value("${user}")
String user;
public void execute() throws MojoExecutionException, MojoFailureException {
System.out.println("user "+ user);
}
}

I'm completely lost

Maven plugin external dependencies are not resolved

I am writing a maven plugin using Mojo classes. The plugin requires a dependency called jcifs and included it in the pom.xml of the plugin. I am able build the plugin and it is deployed into my local repository. I can find the jar file and pom.xml in my local repository.
When I use this plugin in another project in my local system, when executing the plugin goal, I am getting an exception saying the class not found. But the class is coming from the jcifs jar and it is included as part of the dependency for my plugin.
I am not able to figure out what I am missing here. Any help is appreciated
Following is the plugin pom.xml

Error I am getting is class not found exception from the library jcifs

You can do this way, if you want:
**Step 1:**Download the jar file to you local machine
**Step 2:**Moving you jar to you maven repo:Run as shown bellow
Example:
<dependency>
<groupId>org.mock-server</groupId>
<artifactId>mockserver-netty</artifactId>
<version>3.10.1</version>
</dependency>
mvn install:install-file -Dfile=C:\Users\username\Desktop\mockserver-netty-3.10.1.jar -DgroupId=org.mock-server -DartifactId=mockserver-netty -Dversion=3.10.1 -Dpackaging=jar

Maven sibling dependency issue in a multi module project

I have a multi module project with 1 main module (engine) and 2 sub modules (client and server)

- Server
When I try to use the server module in the client, It throws a compilation error that indicates that the server package was not found.

Your modules need
<packaging>jar</packaging>
to overwrite the
<packaging>pom</packaging>
from the parent file.

I have a similar project set-up, but your solution worked just fine for me.
Still one way that could maybe have solved it in your case, would be to define the version in the parent pom using the dependencyManagment
<dependencyManagement>
<dependencies>
<dependency>
<groupId>${groupId}</groupId>
<artifactId>server</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
</dependencyManagement>

The dependency to the server has "test" scope: this means that is will be not included in the runtime package
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>server</artifactId>
<scope>test</scope> <!-- remove this tag -->
<version>${project.version}</version>
</dependency>
for more information on dependency scopes see: here

Ran into a similar problem. This seems to be caused by spring boots' packaging of jar. The Spring boot create an executable jar, sending the classes into BOOT-INF folder inside the jar.
Adding the following into the build\plugins section of the pom resolves the issue (client pom in the case here)
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<forceCreation>true</forceCreation>
</configuration>
</execution>
</executions>
</plugin>
An alternative solution is here : Maven Multi-module dependency package not found

Maven module as dependency on a Web Application

ich have tree modules for my projec, server,client and core. Core module should be imported as jar dependency in other modules.
On eclipse i see no warnings, but if i'm starting the application i'm getting following error :
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [at.ac.tuwien.inso.verteilte.service.HelloServiceImpl] for bean with name 'helloServiceImpl' defined in ServletContext resource [/WEB-INF/appContext.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: at/ac/tuwien/inso/verteilte/services/IHelloService
Caused by: java.lang.ClassNotFoundException: at.ac.tuwien.inso.verteilte.services.IHelloService
this interface is imported on a HelloServiceImpl. HelloServiceImpl is created on the beans as following :
<jaxws:endpoint id="helloService" implementorClass="at.ac.tuwien.inso.verteilte.service.HelloServiceImpl">
i have removed the namespaces because of link protection of stackoverflow :)
By the way, my pom.xml's are :

Thanks you very much for your helps :)
Thank your for your help, i've removed it but the error is the same
<dependencies>
<dependency>
<groupId>at.ac.inso.tuwien.verteiltepraxen</groupId>
<artifactId>core</artifactId>
<version>1.0-SNAPSHOT</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
</dependencies>

I'm not sure what this would actually do, but in the server's POM you are listing core as a dependency and then also excluding it:
<dependency>
<groupId>at.ac.inso.tuwien.verteiltepraxen</groupId>
<artifactId>core</artifactId>
<version>1.0-SNAPSHOT</version>
<type>jar</type>
<scope>compile</scope>
<exclusions>
<exclusion>
<artifactId>core</artifactId>
<groupId>at.ac.inso.tuwien.verteiltepraxen</groupId>
</exclusion>
</exclusions>
</dependency>
Why would you do this? Exclusions are used to tell Maven to ignore some dependencies dragged in by other dependencies in your build.Try removing the exclusion.

You likely just need a mvn clean install in the parent directory to get a fresh war file. Otherwise, clarify what you mean by "if i'm starting the application": using the maven jetty plugin? Deploying to Tomcat? Something else?
