DataNucleus can be easily developed using Maven2.
You also require JDK1.6 and an SVN client (to download DataNucleus) and an editor.
DataNucleus is split into several Maven2 projects and you need these building in a particular
order due to dependencies.
If building DataNucleus up to and including 2.2 you require the "local.repository" project.
The "local.repository" project (in SVN under "platform/local.repository/trunk") provides all
jars required by DataNucleus in a Maven1 style repository layout. It is referenced by all
DataNucleus projects and so you need this to be present. You don't need to build anything here.
Note that if using Maven2 you can refer to this repository specifying the repository layout
as
legacy
.
In DataNucleus 3+ this project is not needed
and the DataNucleus Maven2 repository contains all
necessary jars to build the project.
The DataNucleus "core" (in SVN under "platform/core/trunk") project is the root of all
DataNucleus projects and is the primary requirement for development. You then simply type
(from this project)
This builds the jar under "target" and installs it into your Maven2 repository.
The "api.{xxx}" project (in SVN under "platform/api.{xxx}/trunk") provides persistence
using {xxx} API, and builds on top of "core".
To build the "api.{xxx}" using Maven2, you simply type (from this project)
This builds the jar under "target" and installs it into your Maven2 repository.
The "store.{xxx}" project (in SVN under "platform/store.{xxx}/trunk") provides persistence
to {xxx} datastores, and builds on top of "core".
To build the "store.{xxx}" using Maven2, you simply type (from this project)
This builds the jar under "target" and installs it into your Maven2 repository.
When building "enhancer" (in SVN under "platform/enhancer/trunk") using Maven2, you need
"core" to be built. You then simply type (from this project)
This builds the jar under "target" and installs it into your Maven2 repository.
When building other DataNucleus projects (in SVN under "platform") you follow the same
instructions as shown above. That is, download the project, and type (from that project)
This builds the plugin jar under "target" and installs it into your Maven2 repository.
