An SBT plugin that add some basic git data to the artefact's MANIFEST.MF file.

We cannot take the credit for the idea of this plugin as the source is a fork from Patrick Kaeding's creation

A plugin including some basic information about the state of the repository that the artifact was built from, at the time it was built. This information includes:

• Head revision
• Branch name
• Whether or not there were uncommitted changes
• Build date

This information is included in the MANIFEST.MF file in the jar produced by the package (or assembly) tasks. This can help you track down where a build came from.

Since major version 6, this plugin is cross compiled for sbt 1.x (specifically 1.3.4).

Add the following to your project/plugins.sbt:

resolvers += Resolver.url("hmrc-sbt-plugin-releases",
  url("https://dl.bintray.com/hmrc/sbt-plugin-releases"))(Resolver.ivyStylePatterns)
  
addSbtPlugin("uk.gov.hmrc" % "sbt-git-stamp" % "INSERT_VERSION")

Add the following near the top of your build.sbt file (if you are using a full build config, I'm sure you can figure it out):

import uk.gov.hmrc.gitstamp.GitStampPlugin._

Then, add this lower down:

Seq( gitStampSettings: _* )

Then, just build as normal. This plugin won't add any tasks, or otherwise change the way you interact with SBT.

Your artifacts will just come out with a MANIFEST.MF file that looks something like this:

Manifest-Version: 1.0
Implementation-Vendor: My-Company
Implementation-Title: My Project
Implementation-Version: 0.1
Implementation-Vendor-Id: My-Company
Specification-Vendor: My-Company
Git-Repo-Is-Clean: false
Git-Branch: gitstamp
Specification-Title: My Company
Git-Build-Date: 2013-04-26T17:22:58.538-07:00
Specification-Version: 0.1
Git-Head-Rev: b0d5a67d59dc7c0133aecce2e2ceb18fc8d23597
Git-Describe: release/0.3.5-b0d5a67

The entries starting with Git- were added by this plugin.
