Compose with cds-plugins

[danjoa]

[DanSchlachter]

do we need to copy from server.js to cds-plugin.js and vice versa to allow using the same project as composed and directly? Are we aiming for cds w to behave similar to cds build (i.e. looking at the same files) ? Currently that's not the case

[DanSchlachter]

I think now cds w compose and cds w bookstore lead to the same result (Fiori Apps working with local launchpage, swagger UI, OData v2, same files loaded...)
