Re: [tycho-user] Trouble building an RCP product
I was probably unclear.  Unless your edu.illinois.mobius:edu.illinois.mobius.update project also builds everything, I don’t think that it will find its dependencies unless they’re part of the target platform, available in your project’s p2 update site repositories, or installed to your local maven repository. 

Therefore, I suspect that you’ll either need to build the plugins and feature and create the update site as part of a single Maven reactor, 
Or 
You’ll need to use the “install” goal while building the plugins, features, and products.  That way, when you later run Maven on your update project that builds the update site, it will find the plugins, features, and other artifacts that you just built in the maven repository.

mvn clean install gives me the same error.

Did you try to do an install instead?

I switched to trying update site part of the vogella tutorial: http://www.vogella.com/tutorials/EclipseTycho/article.html#run-the-build

I get the same sort of error saying it cannot resolve the dependencies. I decided to change the category.xml file around to see if I could narrow down the problem. I ended up removing all of my features and adding one of the features in the build target (I randomly picked org.eclipse.cvs). This builds correctly and I can see the new p2 repository with the cvs feature and its plugins looking all correct. 

When I remove that cvs feature and add just one of my features, it goes back to the same error. Is there something I need to do to tell Maven where to find my features? They are built just prior to it trying to create the update site. I'm using the directory structure that vogella suggests, so my recently constructed feature lives in features/edu.illinois.mobius.feature/target/ .

To initiate the maven build, I am using "mvn clean verify".

Thoughts?

I wrote a few days ago about trouble building features and that is working now. I'm on to the next task of trying to get my RCP product constructed from those features. It looks like Maven is saying it can't find the product. I don't understand how Maven/Tycho can put the project name defined by the artifactId in the pom to the product definition file (called core.project) file. I kept waiting for somewhere in the tutorial or other tutorials for a place to identify the product definition file, but it never came.

Any help in debugging this problem would be greatly appreciated. Here is the pom from the product project:
