When trying to follow the Create Addons tutorial (
https://github.com/eclipse/capella/wiki/Create-Addons), the building of the add-on is straight forward (enough) through the Extension Points; when it comes to implementing the Command Handler, it is either so vague as to make it easy to mess up (which I may have done) or it is broken. When implementing the two classes in CommandHandler.java and Command1Hanlder.java files respectively there are a number of errors inherently.
In the CommandHandler class:
- org.eclipse.core.expressions.IEvaluationContext so shouldnt need to be imported
In the Command1Handler class:
- The overridden createCommand method extended from CommandHandler doesnt implement the same inputs, and as written is also not abstract as in CommandHandler.
- ICommand, IProgressMonitor, AbstractReadWriteCommand, EObject, and more are undefined
^ It seems that the way I did it just didnt grab the necessary resources for the above definitions which could be my bad, however, I would recommend more clarity on the second half of the tutorial to at least make the quality of the first half.
