workspace.load_schemes() not finding schemes in a project that is in a group

[loufranco]

If I have a workspace with a project that is inside a group, the schemes in that project are not found with workspace.load_schemes()

This is causing problems in fastlane, which cannot access these schemes.

This zip has a workspace with 2 projects, one in a group, and one at root.

WorkspaceWIthProjectInGroup.zip

I have the following script (using xcodeproj 1.7.0)

require 'xcodeproj'
project_path = './WorkspaceWIthProjectInGroup.xcworkspace/'
workspace = Xcodeproj::Workspace.new_from_xcworkspace(project_path)
workspace.load_schemes(project_path)
print workspace.schemes.to_s.gsub(",", "\n")

This prints

{"DummyRootProject-WORKS"=>"/Users/lfranco/src/WorkspaceWIthProjectInGroup/DummyRootProject/DummyRootProject.xcodeproj"
 "DummyRootProject"=>"/Users/lfranco/src/WorkspaceWIthProjectInGroup/WorkspaceWIthProjectInGroup.xcworkspace/DummyRootProject/DummyRootProject.xcodeproj"
 "DummyProject"=>"/Users/lfranco/src/WorkspaceWIthProjectInGroup/WorkspaceWIthProjectInGroup.xcworkspace/DummyProject/DummyProject.xcodeproj"}

But DummyProject has another shared scheme (DummyProject-NEW). Here is the result of a find for xcscheme files

$ find . -name '*.xcscheme'
./DummyProject/DummyProject/DummyProject.xcodeproj/xcshareddata/xcschemes/DummyProject-NEW.xcscheme
./DummyProject/DummyProject/DummyProject.xcodeproj/xcshareddata/xcschemes/DummyProject.xcscheme
./DummyRootProject/DummyRootProject.xcodeproj/xcshareddata/xcschemes/DummyRootProject-WORKS.xcscheme
./DummyRootProject/DummyRootProject.xcodeproj/xcshareddata/xcschemes/DummyRootProject.xcscheme

And here is xcodebuild -list

$ xcodebuild -list
Information about workspace "WorkspaceWithProjectInGroup":
    Schemes:
        DummyProject
        DummyProject-NEW
        DummyRootProject
        DummyRootProject-WORKS

It really looks to me like FileReference.absolute_path is wrong for type=group -- it doesn't take the group location into account. Here is the relevant Group/FileRef node from the workspace

   <Group
      location = "container:DummyProject"
      name = "DummyProject">
      <FileRef
         location = "group:DummyProject/DummyProject.xcodeproj">
      </FileRef>
   </Group>

The path to the project is ./DummyProject/DummyProject/DummyProject.xcodeproj

This is called from Workspace.load_schemes
