The Project is split into several maven modules.

1. Intro : basic Java 9 module demo.
2. Address: small module required by Person
3. Person: small module showing module dependency between each other
4. Relect: example of open module
5. Reflect: module using deep reflection to open module
6. Prime: service module
7. PrimeFast: provider of prime
8. PrimeGeneric: provider of prime
9. PrimeProbable: provider of prime
10. PrimeClient: client of Prime Service
11. Version: showing correct and incorrect version strings for JDK 9
12. Resources: resources to be accessed from ResourceAccess module
13. ResourceAccess: shows access to resources from another module
14. ModuleApi: shows usage of modular API.
15. ModuleAnnotation: annotated module example
16. LayerInfo: module which has class printing layer info. Used in ModuleApi
17. JshellDemo: module showing usage of Jshell API
18. ProcessDemo: Process API examples
19. CollectionsDemo: Updates to Java Collections
20. HttpDemo: HTTP/2 demo usage
21. StackWalking: new stackwalker api usage
22. StreamDemo: Reactive streams and updates to streaming api

ModuleApi includes:

• FindModule: find module by path
• LayerTest: show layer information for required module
• LoadClass: load class from required module
• Module: print module for module and required ones
• QueryModule: check if module open and exported
• ReadModuleContents: show resources of specified module

ProcessDemo includes:

• CurrentProcessInfo: show info about current process
• Job: a job which sleeps at a regular interval up to a max duration.Interval and duration can be set as parameters on start
• StartProcess: run a new process (uses Job class)
• ProcessStats: obtain a process handle and show some stats
• ManagingProcessPermission: working with permissions

CollectionsDemo includes:

• ListDemo: new way of creating unmodifiable lists
• SetDemo: new way of creating unmodifiable sets
• MapDemo: new way of creating unmodifiable maps

StackWalking includes:

• StackWalker: shows stack walking though the stack of function calls
• GetCallerCallerClass: get the name of a class which calls a method
• PermissionCheck: instantiate stackwalker before and after installing a SecurityManager

StreamDemo includes:

• NumberPrinter: simple pub-sub usage.
• PeriodicPublisher: pulisher which publishes items periodically to custom subscribers instantiated to items
• ProcessorDemo: fitler processor usage
• StreamDemo: new streaming API features
• CollectorsDemo: new collectors features

Build and run Java 9 module:

      mvn clean install 
      
      java --module-path <path-to-target>/<maven-module-name>.jar -m <jigsaw-module-name>/<package-name>.<main-class>
      
      or if there are many modules
      
       java --module-path <path-to-target>/<maven-module-name>.jar:<path-to-target>/<maven-module-name>.jar
        -m <jigsaw-module-name>/<package-name>.<main-class>

As far as I understand one maven module can have only one java module

Classic biuld and run:

   mvn clean install
   
   java -jar <path-to-target>/<jar-name>.jar

Before build change main class name in pom for the demo you want to run
