Re: [tycho-user] Trouble building an RCP product
Here is mine that has been working for months.

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:

<project>

  <groupId>edu.illinois.mobius</groupId>
  <artifactId>edu.illinois.mobius.releng</artifactId>

 </parent>

    <groupId>edu.illinois.mobius</groupId>
 <artifactId>edu.illinois.mobius.product.core</artifactId>
 <packaging>eclipse-repository</packaging>
 <version>1.0.0-SNAPSHOT</version>

 <build>

    </executions>
   </plugin>

</project>

Here is the error output from maven:
