This is one of the issues we need to avoid: having an unneeded ripple effect. GlamourCore was updated, making it necessary to update everything that has a hard version dependency on it. Even worse is that there is actually no change in GlamourCore 3.0.4. This problem gets worse the more configurations we have. ConfigurationOfGTInspectorCore>>version203: spec <version: '2.0.3' imports: #('2.0-baseline' )> spec for: #'common' do: [ spec blessing: #'stable'. spec description: 'version 2.0.3'. spec author: 'AndreiChis'. spec timestamp: '12/07/2014 13:58'. spec package: 'GT-Inspector' with: 'GT-Inspector-EstebanLorenzano.271'; package: 'GT-InspectorExtensions-Core' with: 'GT-InspectorExtensions-Core-TudorGirba.86'; package: 'GT-Tests-Inspector' with: 'GT-Tests-Inspector-AndreiChis.24'. spec project: 'GlamourCore' with: '3.0.3'. ]. ConfigurationOfGTInspectorCore>>version204: spec <version: '2.0.4' imports: #('2.0-baseline' )> spec for: #'common' do: [ spec blessing: #'stable'. spec description: 'version 2.0.4'. spec author: 'AndreiChis'. spec timestamp: '12/09/2014 12:08'. spec package: 'GT-Inspector' with: 'GT-Inspector-EstebanLorenzano.271'; package: 'GT-InspectorExtensions-Core' with: 'GT-InspectorExtensions-Core-TudorGirba.86'; package: 'GT-Tests-Inspector' with: 'GT-Tests-Inspector-AndreiChis.24'. spec project: 'GlamourCore' with: '3.0.4'. ]. The same happens with the subconfigurations of GT, a change in GTInspector leads to a change in the playground. ConfigurationOfGTPlayGround>>version106: spec <version: '1.0.6' imports: #('1.0-baseline' )> spec for: #'common' do: [ spec blessing: #'stable'. spec description: 'version 1.0.6'. spec author: 'AndreiChis'. spec timestamp: '10/06/2014 11:42'. spec project: 'GTInspector' with: '1.0.6'. spec package: 'GT-Playground' with: 'GT-Playground-TudorGirba.38'. ] ConfigurationOfGTPlayGround>>version107: spec <version: '1.0.7' imports: #('1.0-baseline' )> spec for: #'common' do: [ spec blessing: #'stable'. spec description: 'version 1.0.7'. spec author: 'AndreiChis'. spec timestamp: '10/12/2014 19:56'. spec project: 'GTInspector' with: '1.0.7'. spec package: 'GT-Playground' with: 'GT-Playground-TudorGirba.38'. ] And this means that we are better of with configurations having high cohesion and low coupling. And tool support for groups. Stephan
