Trying to set version from git tag

Trying to set version from git tag

[bchazalet]

It works for me with the following build.sbt

lazy val special = project.in(file("."))
.enablePlugins(GitVersioning, GitBranchPrompt)
.settings(
  git.gitTagToVersionNumber := { tag: String =>
    Some("special_tag")
  }
)

Then I get:

special(master)> git tag
[info] v0.1
special(master)> show version
[info] special_tag

Are you using windows? What version of sbt and sbt-git are you pointing to?
And have you reloaded sbt after the tag was created?

Okay, I think I see the problem. I was not originally forthcoming with the entire scope of the issue apparently. My original project is a multi-module project in which I share settings across multiple modules. I tried to simplify the example but I should have done a more exhaustive test. When I created a simple single project with a git tag, it worked as you have pointed out. If it add submodules as additional projects, it will continue to work UNLESS I 'enablePlugins' in one of the submodules, which causes it to reset my git-related settings under the context of that submodule. My original project uses shared settings and that was the root of my problem. Ultimately my ignorance of how sbt loads plugins proliferated this misconception. I should have reconstructed the issue from scratch before submitting it and I would have realized the mistake. Thank you for responding to this issue, and I'm sorry for wasting your time!

No problem, glad you've solved your issue!

Seems I spoke too soon. I tried out this project: https://github.com/mjcramer/sbt-git-test

and here's the output:

~/projects/data/sbt-git-test] (master^) sbt
[info] Loading global plugins from /Users/michael.cramer/.sbt/0.13/plugins

special(master)> git tag
[info] v1.0
special(master)> git branch
[info] * master
special(master)> exit

Now it's back to just printing the sha hash while ignoring my git tag...

[mjcramer]

The behavior came back shortly after I added a "develop" branch to my other project. Now I cannot get it to work at all, even after rolling back all my changes. I dunno if that has anything to do with it, but I'm just throwing it out there...

Your problem is that there is no tag associated with HEAD.

Your v1.0 tag points at some other commit:

special(master)> git show v1.0
[info] commit d76e631bfd524849266f25dcd328883e83be0af4
[info] Author: Michael Cramer <[email protected]>
[info] Date:   Tue Apr 7 09:27:04 2015 -0700
[info]
[info]     init
[info]

You can see the tags associated with HEAD commit in sbt:

special(master)> show git-current-tags
[info] List()

if you create a new tag pointing at HEAD, everything comes back into order:

special(master)> git tag v2.0
special(master)> reload
special(master)> show git-current-tags
[info] List(v2.0)
special(master)> show version
[info] v2.0-special

Ahhhhhh!!! Thanks so much!
