Add warning when checkouts contain project versions not matching declared dependencies

[hugoduncan]

When working with checkouts that are symlinks, it is very easy to checkout out a branch in your sub-project's canonical directory, or otherwise modify it, and forget that the sub-project is symlinked. This can lead to a top level project misbehaving for non-obvious reasons.

Please add a warning when a subproject in checkouts contains a project.clj file with a version different to that listed in the top level project's :dependencies.

I ran into a case where I had forgotten about some checkouts and then saw odd behavior and didn't put the two together. Phil and I discussed it some. A warning would have been very helpful.

I support Hugo's request above.

Perhaps an additional situation should trigger a warning:

• warn if there exists an available release version (non-snapshot) identical to the version specified in the checkout's project.clj.

This covers the case where I've checked out a dep, put it in the checkouts dir, made some tweaks to its code, but haven't bothered to update the main project's :dependencies or the dep's project.clj.

Warning: using my.great.lib version 2.0.4 from checkouts/my-great-lib, not the released version.

Gonna give it a shot. This'll be my first open-source Clojure work, though (I use it at work).

@j-po: thanks for looking into this!

If there's anything you wonder about, want to be reviewed or similar, feel free to ask in this issue – or me directly if you prefer that.

Is this already done? I can see a commit but this issue is still open.

It's not yet, sorry. My life got complicated and I haven't gotten s chance to finish it.

@j-po Would you mind if I fixed this issue? I took a look at it as an entry point to learning the leiningen code base and have a working solution ready for review.

@hyPiRion If so, I've committed my changes, but I have a few questions about the implementation / wouldn't mind a review. My primary concern is for the second warning case:

• warn if there exists an available release version (non-snapshot) identical to the version specified in the checkout's project.clj.

I implemented this by calling aether/resolve-artifacts* for each checkout project to check if there is an available release that matches the declared version. However, I don't like that this is doing a request for each checkout project individually, but if I try all at once and any project isn't found in the remote repositories, an ArtifactResolutionException is thrown and I may mess correctly printing a warning.
