multiproject of multiprojects site generation - infinite loop
I know (from reading the list archives) that the Multiproject plugin
doesn't support multiproject nesting. From my understanding if one has a
project structure like:
projectA
\
projectB
\
- projectC1
|
- projectC2
and you try to run maven multiproject:site from projectA, it will
invoke maven site in projectB instead of maven multiproject:site.
So I tried to override projectB's site goal in the maven.xml with this:
goal name=site
attainGoal name=multiproject:site/
/goal
However, this causes an infinite loop. This is an example of the
transcript:
Starting the reactor...
Our processing order:
projectB1
projectB2
+
| Generating site for projectB1
| Memory: 3M/4M
+
multiproject:site-init:
multiproject:site:
build:start:
site:
.
.
.
multiproject:projects-init:
[echo] Gathering project list
Starting the reactor...
Our processing order:
projectC1
projectC2
+
| Generating site for projectC1
| Memory: 16M/24M
+
multiproject:site-init:
multiproject:site:
build:start:
.
.
.
+
| Generating site for projectC2
| Memory: 30M/36M
+
.
.
.
build:end:
[echo] Now building reactor projects: [projectC1, projectC2]
.
.
Our processing order:
projectC1
projectC2
and over and over.
Is there any way to get this to work?

The problem here is that C1 and C2 inherit B's settings, so the site goal there is actually the site goal from B, which calls multiproject:site. You should wither override the site goal again in C1 and C2 to just attainGoal site:site, or add a check to B's site goal to see if it's being called on B (or on a subproject). I don't know if the first solution will work, though. -- Greetings, Kenney I know (from reading the list archives) that the Multiproject plugin doesn't support multiproject nesting.

Re: multiproject of multiprojects
Hi Dominik,
this is the code fragment I use to clean multi projects.
maven.xml of the main project:
util:available file=${maven.multiproject.basedir}
j:set var=multiproject.exists value=true/
/util:available
postGoal name=clean
j:if test=${context.getVariable('multiproject.exists')}
j:set var=goal value=clean/
attainGoal name=multiproject:goal/
/j:if
/postGoal
Only the main project sets maven.multiproject.basedir in project.properties.
If the 'clean' goal of main project is called all subprojects are also
cleaned.
Don't know if this is the best way to go -- but it's working.

Hi all,
I've been thinking about how to support a multiproject of multiprojects
and couldn't find a working solution to it. I'm facing two problems:
(1) If I could find out whether a project is a multiproject or not, it
would be possible to just delegate the original command (e.g.
multiproject:goal -Dgoal=test) to the multiproject. Otherwise, maven
test on a normal project. Are there mechanisms in maven which allow to
do that?
(2) If I overwrite the site goal in maven.xml of the multiproject to
attain the site goal on each of its components the components themselves
would inherit the overwritten site goal which ends up in an infinite
build loop.
Any help is appreciated.
Thanks,
Dominik

Re: multiproject of multiprojects
Hi Chris, thanks for your advice. As long as there are no native mechanisms implemented in maven your way looks like a feasible solution to me. It'll bring me closer to what I'm trying to achieve.

Re: multiproject of multiprojects
Hi Michal, I'm working at the moment on a maven 1.1 snapshot. It would be nice to have this feature available in maven 1.1. I'll keep my eyes open to when it is going to be introduced in maven 1.1.

The indicator if project is multiproject exists in m2 and will be most likely introduced in maven 1.1 This will be implemented by addition of the new tag in the POM named type. At the moment some plugins are using maven.multiproject.type property of multiproject plugin. But this is not a good thing - but unfortunately the best which curenntly exists. (2) If I overwrite the site goal in maven.xml of the multiproject to attain the site goal on each of its components the components themselves would inherit the overwritten site goal which ends up in an infinite build loop. I will try to fix this particular problem pretty soon (requires minor changes in site and multiproject plugins) But we will need to define common contract which needs to be implemented by plugins in case of multiprojects goal. Possibly this contract can be partially built in into core so for example delegation to given goal/plugin may be sensitive to project's type.
