Submodules are repositories of their own, so their work tree is outside the superproject's work tree. You're attempting to have a submodule of the superproject inside another submodule of the superproject, but this won't work because it does not live in the superproject's work tree (as that doesn't include submodules and their subdirectories). To have nested submodules you must add "module" as a submodule of "framework1" and "module2" as a submodule of "framework2". Then git will handle them just fine (assuming you use the --recursive option for "git submodule update" and friends). Of course that means that if you want to record a new commit of a sub-submodule in the superpoject, you'll have to commit that in it's parent submodule first and then can record that commit in the superproject. (But if "framework1" wouldn't depend on a specific version of "module", there would be no reason to put it inside it in the first place, right?) > Limiting the traversal up the tree, etc.?

But at least since 1.6.2 git should issue a meaningful error message. With current master I get: $ git add sub/file fatal: Path 'sub/file' is in submodule 'sub' What version are you using? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
