Eclipse logical directory grouping

Question

Is there any way, with the Eclipse IDE, to have a "master" folder containing several related projects?

The reason I want this is because I have several Maven webapps. With Maven it is convention to have a "master" project which builds all the dependent projects. Without the ability to logically group these projects in Eclipse my project structure looks something like this:

--master-proj1
--proj1-core
--proj1-dep
--master-proj2
--proj2-core
--proj2-dep

And of course these will be sorted alphabetically making it even worse. I'd rather have a couple folder where I can store each project:

--project1
  --master
  --core
  --dep
--project2
  --master
  --core
  --dep

Is this possible?

Answer 1

You could create working sets for your top-level groups like project1 and project2 (Package Explorer View Menu -- little triangle in the upper right corner > Configure Working Sets...), configure the package explorer to view these as top-level elements (Package Explorer View Menu > Top Level Elements > Working Sets), and add the dependent projects into them (using drag and drop or Configure Working Sets...).

Answer 2

A Workspace is considered to be a logical grouping of many related projects.
Right now i have 3 workspaces, one for a work in Python, one for a work with Servlets, and a "playground" :-)

Any time i run out of ideas for one work, i go File -> Switch Workspace, and do the other.
