Integrated an maven project to an existing maven project

I have a existing db Maven Java project in eclipse. And the second is also in Maven project with a global pom and subdirectory pom. What is the easiest way to integrate both projects into one project ? I tried to add these subfolders with the pom file. But i got the failure modules is an invalid element. Maybe there is another way to add the second project. The first project is an embedded neo4j db and the seconde project is the jung frame work. Which has also sub pom files.

running mvn package -e didn't give any noticeably different output and mvn package -X didn't give me anything I could understand. How would I go about fixing it? Looking in the pom.xml file, the only release related thing I could see was the <release>10<\release> but idk what to change that to if that is the problem. I'm assuming I have to change things in the file to fit what versions of java and maven I have but I'm pretty new to the both of them and don't really know what I'm looking for.

Maven Surefire Test Rerun Parameter Does Not Re-Run Failing Tests

Maven surefire does not rerun failing tests. I tried to change the surefire version to 3.0.0-M4, 3.0.0-M5. Use commandline option -Dsurefire.rerunFailingTestsCount=3, added <surefire.rerunFailingTestsCount>2</surefire.rerunFailingTestsCount> to the pom file, and added 2 to the configurations of surefire plugin; ran mvn install multiple times. However, nothing seems to work and Surefire runs failing tests just once. The pom file of the project I am working with is:

I am a little bit lost what might be causing the failing tests to be executed multiple times as I tried a lot of different suggestions on stackoverflow.
Thanks in advance!

There are some missing configurations under maven-surfire-plugin. Please, have a look at the working configuration:

java.lang.NoClassDefFoundError when jndi lookup for API

I am having a NoClassDefFoundError exception when I execute a jndi lookup for an API in an EJB. Here is what my project looks like :
java project
In my project I have 2 APIs, 2 EJBs and 2 Clients. Both my clients work. What I am trying to do is make a function of EJB ejb-admin-bean call ejb-31-entity-bean-exemple-bean by calling ejb-31-entity-bean-exemple-api.
Here is the code that :
package admin.entity_bean_ejb;
import javax.ejb.Stateless;
import javax.naming.InitialContext;
import admin.entity_bean_api.StatelessSessionAdmin;
import enterprise.entity_bean_api.StatelessSessionLocal;
/**
* The stateless session bean.
*/
#Stateless
public class StatelessSessionAdminBean implements StatelessSessionAdmin {
#Override
public String helloWorld() {
return "the room is called " + getShowRoomName();
}
//test d'appel de l'api d'encheres
public String getShowRoomName() {
StatelessSessionLocal sb;
try {
InitialContext ic = new InitialContext();
sb = (StatelessSessionLocal) ic.lookup("java:global/ejb-31-entity-bean-example-bean/StatelessSessionBean!enterprise.entity_bean_api.StatelessSessionLocal");
final String roomName = sb.getShowRoomName(1);
return roomName;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
The class not found is StatelessSessionLocal from ejb-31-entity-bean-example-api
Here is the stackTrace :
javax.ejb.EJBException
at com.sun.ejb.containers.EJBContainerTransactionManager.processSystemException(EJBContainerTransactionManager.java:752)

You need to add the cobertura goal to your pom.
