[tycho-user] tycho dependency resolution problem 
Hey folks,
I'm having a problem getting tycho to build my project. I have created a sample version of my project that exhibits the same problems.
I basically have 2 eclipse plugins, core and main. main depends on core. core depends on org.springframework.core 3.0.6.RELEASE
when I mvn install from the top level (parent) I get an error saying that main depends on core, which depends on spring, which can't be resolved. 
when I build core by itself, it builds just fine.

Here is my sample project layout.

project/
project/core/
project/core/pom.xml
project/core/build.properties
project/core/META-INF/
project/core/META-INF/MANIFEST.MF
project/core/src/
project/core/src/main/
project/core/src/main/java/
project/core/src/main/java/foo.java
project/pom.xml
project/main/
project/main/pom.xml
project/main/META-INF/
project/main/META-INF/MANIFEST.MF
I have included the sample project.tgz as an attachment, but if this attachment doesn't work, you can find it at this url 

http://wx.hemna.com/tycho-project.tgz

Here is the error output I get.
