rebuilding claimed version snapshot from historic commit

[esz]

Currently, reckon doesn't allow me to rebuild historic snapshots from old commits (with clean repo) if the subsequent normal version has already been released. Let's assume the following project setup:

Plugin settings:

reckon {
    normal = scopeFromProp()
    preRelease = snapshotFromProp()
}

Repo:

                      0.2.0
                        |
0-------X-------0-------0----...
                |\
                | \-----0----...
                |       |
              0.1.0     |
                      0.1.1

Now I want to rebuild X from a clean repo state, but reckon complains, saying:

* What went wrong:
Could not determine the dependencies of task ':compileJava'.
> Could not resolve all dependencies for configuration ':compileClasspath'.
   > Reckoned target normal version 0.1.0 has already been released.

In my opinion it should be possible to rebuild 0.1.0-SNAPSHOT from X when there are no local changes present and the 0.0.1 Tag is the lowest normal version within the successor commits reachable from X.

Of course I can still use -Preckon.scope=major or -Preckon.scope=patch to build 1.0.0-SNAPSHOT or 0.0.1-SNAPSHOT in this example, if the subsequent normals have not been claimed yet.

But the behavior above can be particularly painful, since I am not able to import old revisions (e.g. when im git bisecting) of my project into Eclipse using buildship with the build failing.

I wrote a small (failing) test, illustrating the expected behavior: esz/reckon@dbe10e34ac53a514cb6b6b750e9209c6673c4d01

What do you think about that? Am I just overlooking some valid reason for this restrictive behavior? If you think this would be a useful addition, I'd contribute happily!

I've defaulted to being restrictive where I wasn't sure if the behavior should be allowed.

I agree with you that this should be allowed, though I don't know if it's a simple change.

My initial thoughts are that the behavior should be:

• For any significant tagged version in claimed you can only rebuild it if you're on the same commit.
• For an insignificant version you can rebuild it only if that commit is in the history of the claimed version.
• All other scenarios that currently fail should still fail.

If you want to check out 0.7.0-rc.1 this should work now. Thanks for opening and providing a test!

Hi, just tried 0.7.0 Works like a charm! Thank you!
