Hi, I'm trying to define a dependency on a group of BaselineOf. specifically #core of github://pharo-graphics/Bloc/src. I've looked at this https://github.com/Metacello/metacello/blob/master/docs/GettingStartedWithGi... which recommends using import:provides: baseline: spec <baseline> spec for: #common do: [ "Sample defines the group 'default'" spec baseline: 'Sample' with: [ spec repository: 'github://dalehenrich/Sample:master' ]. spec import: 'Sample' provides: #('default'). "OtherSample *also* defines the group 'default'" spec baseline: 'OtherSample' with: [ spec repository: 'github://dalehenrich/Sample:master' ]. spec import: 'OtherSample' provides: #('default'). "'default' can now be successfully resolved, even though both projects define the same name" spec package: 'OtherProject-Core with: [ spec requires: 'default' ] ]. However this code is confusing... both Sample & OtherSample provide `default`, so on what does `OtherProject-Core` actually depend? In the examples here https://github.com/Metacello/metacello/blob/master/docs/LockCommandReference... there are groups with the name of the project in them ('External Core' 'External Tests'), but this won't work if I don't control the project I am loading, plus it feels like a hackish workaround. Also, can it be unified with the way ConfigurationOf works? Thanks, Peter
