a little too minimal a test case :) None of the source seems to be included, nor maven.xml or project.properties...

Description:
I'm trying to generate "1.4 friendly" compiled classes. I'm getting failures on the assert keyword. Here's a rundown of my multiproject structure:

root/
    project.xml (extends root/service/project.xml)
    project.ent
    common/
        maven/
            project.properties
            project.xml (Parent)
            entities/
                versions.ent
                dependencies.ent
                developers.ent
    service/
        maven.xml
        project.properties
        project.xml (extends root/common/maven/project.xml)
    ejb/
        project.ent
        project.properties
        project.xml (extends root/project.xml)

I have the maven.compile.source and maven.compile.target properties set in root/service/project.properties. Yet when I run "maven multiproject:install" from my root directory I get a warning and error regarding the assert keyword. If I put these properties in a root/project.properties file it works fine. Can anyone tell me if this is a bug or if I'm doing something wrong?

----------------------------------

Just to follow up with some more info that I discovered...

I created a root/maven.xml to echo the maven.compile.* properties during the build. Somewhere along the way my property values are being lost:

build:
    [echo] maven.compile.source=1.4
    [echo] maven.compile.target=1.4
multiproject:install:
multiproject:projects-init:
    [echo] Gathering project list
Starting the reactor...

<snip>

xdoclet:ejbdoclet:

java:prepare-filesystem:

java:compile:
    [echo] maven.compile.source=1.3
    [echo] maven.compile.target=1.1


So is the problem in the property inheritance, the java plugin, or the multiproject plugin? Your help is greatly appreciated.

-----------------------------------

I've been doing a lot of trial and error with this problem and I've narrowed it down to what I think is a problem in multiproject environments with inherited properties. It is *not* an issue strictly with the maven.compile.* properties as I've previously mentioned. I'm attaching a jar file of my stripped down example to demonstrate. In my example, I'm demonstrating the problem with the maven.repo.remote property. To replicate the problem, do the following:

* Edit project.properties under test/ and change maven.repo.remote to something other than ibiblio.
* Edit test/service/myservice/ejb/project.xml with a dependency (something NOT on ibiblio, but on the remote repo specified previously)
* Remove this dependent jar from your local repository so it's forced to download it again
* From test/service/myservice, execute a maven goal (I generally do clean)

This should fail to download. Strangely, if I run the same maven goal from test/service/myservice/ejb, it DOES download! Anyone have a clue what's happening here?
