问题
Following the Vogella Maven-Tycho tutorial, I have ran into a runtime error.
After exporting my project I am unable to launch it. The following error occurs after my headless build, and also after an eclipse export wizard build.
It triggers the following runtime error:
!SESSION 2018-08-23 13:42:44.875 -----------------------------------------------
eclipse.buildId=unknown

I believe this might be triggered because the tutorial has you move the rcp.product file into a new directory. I have already tried to go to Run -> Run Configurations and have added the rcp plugin.
Here is my project structure. The missing product file was moved from ./bundles/com.voglla.tycho.rcp/ -> ./releng/com.vogella.tycho.product/
Project Structure
Please let me know if you need more information.

You need to add the "com.vogella.tycho.rcp" plug-in to the feature "com.vogella.tycho.feature". That is, the feature should contain both com.vogella.tycho.plugin1 & com.vogella.tycho.rcp.
The com.vogella.tycho.rcp plugin was missing, since the product is configured to be based on features, and that missing plugin is not part of a feature.
So this is a bug in the instructions, but it is unfortunate that one cannot make comments on the original site http://www.vogella.com/tutorials/EclipseTycho/article.html#exercise-tycho-build-for-products.
