Hi everyone,

I am a complete beginner and I will need to use gmf for my bachelor thesis. I have been following the tutorial but I run into a problem when I reach the part where I need to generate teh diagram code. I get a weird error that I have not been able to solve, and I have not seen anything similar online. Is there anyone that knows how to fix this or can point me in the right direction? It seems to be something relating to the compiler, so I think it is relevant to mention that I have set the compliance level to 1.5, but I have had the same issue when it was at 17.

Hi,

Which tutorial are you refering to?

You mention "generating the diagram code", so it looks like you are trying to use GMF *Tooling* (https://projects.eclipse.org/projects/modeling.gmf-tooling), which is (was) a set of generators and associated tooling to produce Java code which targets GMF *Runtime* (https://projects.eclipse.org/projects/modeling.gmf-runtime).
GMF Tooling has been inactive/unmaintained for quite some times unfortunately; I think it can be considered abandonned (last commit was 7 years ago: https://gitlab.eclipse.org/eclipse/gmf-tooling/org.eclipse.gmf-tooling).

Hi,

This is the tutorial that I was referring to: https://wiki.eclipse.org/Graphical_Modeling_Framework/Tutorial/Part_1#Tooling_Definition

Your reply made me realize that I had overlooked some things in the "Setup" part of the tutorial, so I went and installed what was missing. This made the error from my previous post go away, but I am still at a dead end because I now have a different error at the same step (generate diagram code). I think that there is something wrong with my eclipse environment because I don't see what could have possibly gone wrong. Besides, the solution to this tutorial can be found online, and I am unable to run it, which also makes me think that there is something wrong with my eclipse environment. I will try to start over from scratch and see if that helps.

Hi again,

I have now uninstalled and reinstalled Eclipse as well as all of the required plugins. I am able to run the entirety of the tutorial (https://wiki.eclipse.org/Graphical_Modeling_Framework/Tutorial/Part_1#Setup ) until the very last step where I need to open the mindmap example. The problem I have is that the mindmap does not appear in "examples", and there are also numerous errors in the new Eclipse runtime that pops up when I run the application. Does anyone have any insight on what could be wrong? I have the same issue when I use the tutorial solution that is available online.
