How to reuse the same SVN resource in multiple places

Question

In SVN I have following folders:

• some_path/solution_A/some_project
• some_path/solution_B

There is some project inside solution_A that I want to reuse in solution_B. It's not a problem in ClearCase or Perforce where I can map this project to any folder inside solution_B within the workspace. But how can I solve this problem (checkout some_project within solution_B workspace) in SVN without creating duplicates in my SVN tree?

Answer 1

• Read about SVN Externals
• Map some_path/solution_A/some_project as target of external folder definition in some_path/solution_B: you'll see nothing (except new commit appeared) changed in repository for solution_B, but when you'll checkout solution_B with externals into WC (or update existing WC) - you'll get new folder in tree. identical to solution_A/some_project
