I have projects populated with settings, as include paths, and definitions. If I want to create a new configuration of the same project it is necessary to rewrite all of them by hand. Or probably there is a way to export the settings, maybe writing by hand a file, whatever is faster then rewriting one by one in the settings windows.
You can easily add a new configuration to your existing project, see https://mcuoneclipse.com/2016/05/19/build-configurations-in-eclipse/
If you want to make a new project with your settings, the easiest way is to copy the project:
There is just one thing you need to consider: the launch configurations.
You can export and import projects in the following way: https://mcuoneclipse.com/2012/05/07/exporting-and-importing-projects-in-eclipse/
If using KDS: it is even simpler: copy the project in the Eclipse Project Explorer, then paste it and give it a new name.
I hope this helps,
It helps. If at a time I change the settings in the active project and I want to export the changes to the other non active, what do You suggest???
