Re: [mdt-papyrus.dev] Use of org.eclipse.jdt.annotation in Papyrus

["Christian W. Damus" <give.a.damus@xxxxxxxxx>]

Hi, Camille,

The work-around worked for me.

I do think the team should agree on the external tooling dependencies (such as these annotations) that it will use in the sources.  We need to have consistent set-ups of our development environments so that we don't introduce problems in the builds or in other developers' workspaces, as has happened before with inconsistent Java source/binary compatibility compiler settings etc.  We should either encourage the use of these annotations in the API signatures across the Papyrus codebase or remove them from this project that uses them.

BTW, this reminds me that one task I would like to volunteer to undertake is to develop an Oomph model for Papyrus.  Does the team have any interest in this?  (I wouldn't want to expend the effort if it won't be used)

Thanks,

Christian
