Re: [tycho-user] Exception building RCP with local target definition 
Thank you for your response Tobias,
but your solution does not work for us, since we have some external employees who work on images that are not allowed to go online. I think i have a solution now, it seems that committing the whole export to svn was not a good idea (yes i know, committing 500 MB of binary data is never a good idea :-) ). When i export the target directly to a network drive, building offline works.

The error message points to p2 complaining about broken repository content. I know what exactly is wrong, but I would suppose your exported target definition is broken.

Can you not use the normal offline mode? Run the build once offline to allow Maven and Tycho to prime the local repository, and then run it with -o.

Regards
Tobias

Subject: [tycho-user] Exception building RCP with local target definition

Hello,

In our build environment, we have the need to have our target platform
available offline.
To achieve this, i have created an eclipse target file based on p2
update sites.
I exported this target definition with the eclipse built-in export
(target editor -> export) to a local directory.
After that i created a new target file using the exported repository.
This target file is used in the tycho build (version 0.15) of an rcp
project.
The build fails with an error when the dependencies of the repository
artifact are resolved:

What can i do to avoid this?
Using an exported target definition for a plug-in project worked fine.

Best regards,
   David
