> The situation is quite complex to explain. I've a parent pom that defines dependencies
in depMgmt. There's two projects in the multimodule project, the second depending on the first.
> Excerpt (parent/depMgmt):
> {code:xml}<dependency>
>   <groupId>ch.qos.logback</groupId>
>   <artifactId>logback-classic</artifactId>
>   <version>${logback.version}</version>
>   <scope>runtime</scope>
> <optional>true</optional>{code}
> First child (redefines scope only):
> {code:xml}<dependency>
>  <groupId>ch.qos.logback</groupId>
>  <artifactId>logback-classic</artifactId>
>  <scope>compile</scope>
> </dependency>{code}
> Second child:
> {code:xml}<dependency>
>  <groupId>org.slf4j</groupId>
>  <artifactId>slf4j-api</artifactId>
> </dependency>
> <dependency>
>  <groupId>m3pb</groupId>
>  <artifactId>subproject1</artifactId>
>  <version>${project.version}</version>
> </dependency>{code}
> When running with maven 2, it works. When ran with maven 3, it fails on the second project,
with a NoClassDefFoundError on the logback jar.
> I seem to understand this is actually a bug in maven 2: as the depMgmt defines optional=true,
it shouldn't have been working in maven2 without redeclaring the dependency in the second
project. 
> From my understanding:
> * With maven 2, the transivity is taken in account and gives logback through the subproject1
link (from the second)
> * With maven 3, this just doesn't work and this is the correct behaviour.
> Please excuse my basic analysis. 
> I'm attaching a test project to let see more precisely the problem.
> If you need any help, please let me know.
> Cheers
