Hi Nacho, thanks a lot for the overview.
As a start I have changed the way we generate the pom.xml. There is still the Gradle MavenPom object. But under the hood it configures a native Maven MavenProject object which we now also use to generate the pom.xml. This MavenProject object is exposed. You can access it by: pom.mavenProject Those changes are committed and will allow you to add all the pieces to your pom that you need. The MavenPom object has a couple of responsibilities. For one it provides convenient methods to configure the underlying native Maven object. It doesn't offer much in this respect yet but that will grow. One typical example would be an addDependency method as the MavenProject object only offers setDependencies(List ...). Another responsibility is to provide hooks. The hooks are not committed yet but should be done soon (today). They will allow you to hook in a listener that gets an instance of the MavenPom object after the autogeneration has happened. Another hook will provide access to the XML before it is written to disk. On Tue, Feb 23, 2010 at 5:22 PM, Nacho Coloma <[email protected]> wrote: > Good.
