I have now tested other types of models and always get this same exception. This seems to be a general bug with Papyrus. Thank you. I can't reproduce with the current code (neither master/neon nor for mars SR1) The described NPE does not depend on your diagrams, but may depend on the exact sequence of your actions. Can you please provide step by step way for you to invoke the export? These are the steps to reproduce this exception (Eclipse 4.5.0 with Papyrus 1.1.0): 1. Open the project containing the model 2. Navigate in the Project Explorer to the folder containing the model 3. Right click on the model and select "Export All Diagrams..." 4. Optionally change the output format 5. Click OK I have Eclipse set up to send exceptions. You may access the last one I submitted here: https://dev.eclipse.org/recommenders/community/confess/#/incidents/Ngz8jQw3ehVzJ64ro4nlzVvKT1btRBRuGIC05i9jckWnuYtwHDyRqf1OJC3EUNjd Thank you. I've just verified that the bug is not reproduced anymore in the most recent version 1.1.1, available at http://download.eclipse.org/modeling/mdt/papyrus/updates/releases/mars/. Please update I am sorry, but the bug is still there with Papyrus 1.1.1. Here is the latest submission: https://dev.eclipse.org/recommenders/community/confess/#/incidents/lLXEy9tlu8kMkIFKliI6s6qnF7f2rQEQ0n3yBW4rv4X7uaWWxQb0pMmoVj6OkJBi Thank you. I struggled with a problem like this for a short while because my model directory is not inside my eclipse workspace directory. If your setup is the same, then you can work around this by [not optionally] browsing to and selecting the exact same output directory that the "Export All Diagrams" dialog says it will use. I have a code fix that alleviates this annoyance, I will attach it presently. Created attachment 255870 [details]
Code Fix for "Export All Diagrams" issue.
I, Fred Eckertson, wrote 100% of the code changes I am providing.
This code contains no cryptography
I have the right to contribute code to Eclipse.
I contribute this content under the EPL.
The fix consists of the addition of lines 170-183.
Without this fix, Papyrus fails to export the diagrams if the model directory is not in the eclipse workspace directory unless one first browses to and selects an output directory manually. This is despite the fact that a valid output directory (which will typically be the desired output directory) is displayed by default in the "Export All Diagrams" dialog.
I am out of the office these days, I cannot try Fred's suggestion right away. However, I would like to note that by default versioning plug-ins such as EGit store all assets outside the workspace. This is a recommended practice and greatly facilitates migration between Eclipse versions. In a properly organised development environment workspaces contain solely metadata. The contrary is the exception rather than rule. Fred: I doubt this is the correct place to submit a code fix. I advise you to seek guidance on this. And thanks for sharing. Regards.

I bumped on it today with Eclipse Neon, and even opened a dupe bug. It seems all Papyrus versions from 1.1.0 to 2.0.0 are affected. The workaround suggested by Ulf Olsson works in some cases. Sometimes re-initialising Eclipse before trying it helps. New Gerrit change created: https://git.eclipse.org/r/77996 Gerrit change https://git.eclipse.org/r/77996 was merged to [master].
