Re: [tycho-user] tycho dependency resolution problem 
All recent orbit builds provide corresponding p2 repositories on their
download pages, see [1] for example. These p2 repositories can be
directly used to resolve Tycho project dependencies. If you are using
implicit target platform configuration, you can add something like this
to your pom.xml


<repositories>
  ...
  <repository>
    <id>orbit</id>
    <layout>p2</layout>

<url>http://download.eclipse.org/tools/orbit/downloads/drops/R20110523182458/repository/</url>
  </repository>
  ...
</repositories>

ok I believe I found my issue. I was missing the tycho plugins section
in the main/pom.xml.....now I have other issues related to not being
able to find
a suitable org.apache.commons.logging dependency that spring core has.

Is there a way to get maven/tycho to use an eclipse orbit repository to
fetch osgi versions of jars?

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.
