[jira] Commented: (MNG-1916) Making it possible for plug-in to add
modules to the reactor programatically

Jason van Zyl commented on MNG-1916:
------------------------------------
You can use the same code the new site plugin is using in order to create your own plugin system for your particular domain.

> I would like to be able to specify a number of directories as plug-in directories, automatically discover every plug-in in those directories and include them in the reactor. As I understands it the reactor with it's modules ({{org.apache.maven.execution.ReactorManager}}) is created in {{org.apache.maven.DefaultMaven}}. If I understands this correctly maven plug-ins can't add projects to the reactor programatically.
> My proposition to solve this is to add a phase which will be executed after the pom.xml is parsed, but before the information stored in Model/MavenProject is used, and most importantly before the {{ReactorManager is created}}. Then you can add information to the MavenProject programatically, increasing the flexibility for plug-ins.
> I am not fluent in the maven2 code base, but it seems to me that this require quite a lot of changes to the code. As I understands it the life cycle starts after the {{ReactorManager}} is made, and therefore after the information in Model have started to be used.
