[jbosstools-issues] [JBoss JIRA] (JBIDE-12475) Split JBoss Tools into several functional groups of components for migration to Github

[Max Rydahl Andersen (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-12475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718121#comment-12718121 ] 

Max Rydahl Andersen commented on JBIDE-12475:
---------------------------------------------

thinking about this we need to keep the exact scripts we do for this since we'll be seeing commits in svn until the very last minute so we'll need to be able to rerun these again and again.

You say runtime lost its history - how did you "move it" ?

> As part of the planned migration to git [0] it's been suggested that we combine some of the existing components into larger groups [1] so that it's more manageable in terms of checking out sources and tagging/branching [2]. 
> Because 25 is a large number, and 1 is a small number, and we need some happy compromise.
> Here's my proposal for how to divide the JBT 4.0 sources into 7 github repos (chunks), comprising 4 tiers of dependency. This is akin to the +0, +1, +2, +3 labels assigned to projects within the annual Eclipse release trains [3], used to define delivery times based on dependencies between projects.
> {code:title=TIER 0: no upstream JBoss.org chunks}
> Base = tests + common + usage
> {code}
> {code:title=TIER 1: 1 upstream chunk, Base}
> AppServer = openshift + as + archives + jmx + ws
>   -> depends on Base
> Hibernate/Birt/Freemarker = hibernate + birt + freemarker
>   -> depends on Base
> Visual Editing = vpe + xulrunner + gwt + struts + jsf + jst + cdi
>   -> depends on Base
> Forge = forge
>   -> Depends on Base
> {code}
> {code:title=TIER 2: 4 upstream chunks}
> Seam/Runtime = Seam + Runtime 
>   -> depends on Hib + Vis + AppServer + Base
> {code}
> {code:title=TIER 3: 5 upstream chunks}
> Central/Examples/Maven/Portlet = central + examples + maven + portlet
>   -> depends on Seam/Runtime + Hib + Vis + AppServer + Base
> {code}
> I'm not thrilled with the names of the chunks, as something like "Central/Examples/Maven/Portlet" doesn't exactly roll off the tongue. If you have better names for the chunks, please suggest them.
> But regardless of name, I think the above separation of concerns, and the implied build sequence workflow makes a lot of sense.

> [3] http://wiki.eclipse.org/Juno/Simultaneous_Release_Plan#Milestones_and_Release_Candidates - "These delivery times are based on the dependencies between projects. They are labeled +0, +1, +2, and +3, with +0 coming first (the Platform) and +3 coming last (EPP). Projects themselves decide if they are +0, +1, +2, or +3."
