java.lang.NoClassDefFoundError using Wildfly, Maven, Rest? - eclipse

Question

I have 2 Maven projects, and let's say I'm using Project2 as a dependency in Project1.
Project2 is using Java Security and has some encrypting methods.
I ran the command mvn install in Project2 and then this is how I am adding the dependency in Project1:
<dependency>
<groupId> myProject2groupId </groupId>
<artifactId> myProject2artifactId </artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>compile</scope>
<type>jar</type>
</dependency>
And I added this in Project2 pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<goals>
<goal>test-jar</goal>
</goals>
</execution>
</executions>
<configuration>
<finalName>ProjectJARs/project</finalName>
</configuration>
</plugin>
The import of the classes and methods of Project2 in Project1 are perfectly working, giving me no errors when I try to compile as a Java Application and printing in console.
But when I'm running it on the Wildfly server and applying GET/POST methods from my rest endpoints, it gives me this error:
org.jboss.resteasy.spi.UnhandledException: java.lang.NoClassDefFoundError: simmetricClasses/SimmetricCriptography
(In Project1 Maven Dependencies I can see Project1's folder with this [without test code])
Can someone help me with this error?
Thanks a lot

This is the pom.xml of the project I want to use as a module:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>mygroupId</groupId>
<artifactId>myartifactId</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<plugins>
<plugin>

<artifactId>maven-surefire-plugin</artifactId>

</configuration>

</executions>
<configuration>

</plugin>
</plugins>
</build>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
</project>
Is this correct?
