[Eulergui-user] Split EulerGUI code in Maven modules

[Jean-Marc V. <jea...@gm...>]

Hi


Currently EulerGUI is big monolithic piece of code, with lotsof
dedendencies.

It's not suitable for deployment of applications built the framework, or of
the server, etc.

So we want to split EulerGUI code into Maven modules.


Dependencies will be:

eulergui_core -> eulergui_api -> eulergui
eulergui_core -> eulergui_api -> eulergui_server
eulergui_core -> eulergui_eye -> eulergui_minimal -> eulergui

cf
http://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Inheritance_vs_Project_Aggregation

There will be both Project Inheritance and Project Aggregation, with
eulergui_parent being the parent and module owner.

Directory structure will be:

trunk
├── eulergui
│   └── pom.xml├── eulergui_api
│   └── pom.xml
├── eulergui_core
│   └── pom.xml
├── eulergui_eye
│   └── pom.xml
├── eulergui_minimal
│   └── pom.xml
├── eulergui_parent
│   └── pom.xml
└── eulergui_server
    └── pom.xml

The green ones will be created.

Migration path:

   1. in eulergui/

   extract parent POM (currently pom.xml ) into ../eulergui_parent/pom.xml ;

   current pom_jar.xml becomes pom.xml ;

   ../eulergui_parent/pom.xml becomes module owner
   2. trunk/eulerscala will disappear, and Scala build will become regular
   build

   changes in pom.xml
   3. create empty eulergui_core, eulergui_api, eulergui_eye,
   eulergui_minimal

   each with a small POM, declaring the dependencies above
   4. eulergui_server will become child of eulergui_parent , and dependent
   of eulergui_api
   5. the code is still in eulergui/ ;

   I can begin to move some packages to eulergui_core, eulergui_api,
   eulergui_eye, eulergui_minimal ;

   I can begin to add Scala code, of replace some Java with Scala

Maven module instead of just having dependency

What's the point of having module instead of just having dependency to
other projects , that I also manage ?

I got my answer here :
http://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Aggregation

Comment welcome !
