Updating ecore resource slows down build process [message #1832450]

During each build process in Eclipse 4.16, the progress view stalls for minutes with the message 'Building myProject: Updating resource myModel.ecore', which sums up during an office day. That file is about 188kB large.
Is there anything I can do to accelerate the build process, e.g. preven that resource update unless it actually changed? (Is this the right forum?)
Thank you in advance.

Does this project have an Xtext nature? I.e., this in the .project file:

<nature>org.eclipse.xtext.ui.shared.xtextNature</nature>

You can make .* files visible via the view menu's Filters... and uncheck the .* resources item.

Nothing in EMF itself does such building...

Ed, thanks for the hint. Yes, it has Xtext nature, because we use an Xtext based DSL as a boiler plate code generator in the project. I'm checking what happens when it is disabled. Maybe I'll just have to move the Ecore file to a separate project without Xtext.

That is a helpful workaround indeed: Keep Ecore files and 'actual' Xtext stuff in separate projects. Ecore code generation to the same project is no problem via the genmodel's settings.

Hi

See https://www.eclipse.org/forums/index.php?t=msg&th=1105235&goto=1832475&#msg_1832475 on the Xtext forum for clearer guidance. The *.ecore can live with its built editor and NO Xtext nature, it is only the developer's build stuff that needs to be kept separate with an Xtext nature.

Regards
