If you have a multi-module project you need a structure like the following which will also be represented by the folder structure as well.

+-- root (pom.xml)
     +--- module-1
     +--- module-2
     +--- module-war 

Whereas the root module contains a thing like this:

  com.test.project
  parent
  1.0-SNAPSHOT

  
    module-1
    module-2
    module-war
  

In the module-1 your pom should look like this:

  
    com.test.project
    parent
    1.0-SNAPSHOT
  

  module-1

  dependencies for the module

in module-2 it look more or less the same..and in the war module it looks like:

  
    com.test.project
    parent
    1.0-SNAPSHOT
  

  war
  module-war

  dependencies for the module

If you have dependencies between the modules for example module-1 depends on module-2 it looks like the following in module-1:

  
    com.test.project
    parent
    1.0-SNAPSHOT
  

  module-1

  
    
      ${project.groupId}
      module-2
      {project.version}
    

    ..other dependencies..

  

To build and package your project you will go to parent folder and do simply a

mvn clean package
