sbt-git
The sbt-git
plugin offers git command line features directly inside sbt as
well as allowing other plugins to make use of git.
Maintenance status
This plugin is community maintained. See https://github.com/sbt/sbt-git/issues/182 if you'd like to help.
Installation
As of 1.0.0
this plugin requires at least Java 8.
The latest version supporting Java 7 was 0.9.3
, while the latest version supporting Java 6 was 0.8.5
.
Latest:
Add the following to your project/plugins.sbt
or ~/.sbt/1.0/plugins/plugins.sbt
file:
addSbtPlugin("com.github.sbt" % "sbt-git" % "<version>")
Prior to sbt 0.13.5:
Add the following to your project/plugins.sbt
or ~/.sbt/0.13/plugins/plugins.sbt
file:
addSbtPlugin("com.typesafe.sbt" % "sbt-git" % "0.7.1")
additionally, use one of the older README.md files: (https://github.com/sbt/sbt-git/blob/v0.7.1/README.md)
JGit
JGit is a Java interface to git that allows some git operations to be performed in the JVM without invoking an external git executable. By default, this plugin uses JGit for read-only operations such as inspecting HEAD; for write operations, it assumes a git executable is present and on the PATH and it uses that.
In certain circumstances you may want to force the use of JGit or an executable for both read-only and read-write operations; for example, if no git executable is present (e.g. you use windows and you haven't installed git or it's not on your PATH) you need to disable the console interface, or if you rely on a git feature that JGit does not support (e.g. worktrees) you need to disable the JGit interface.
The following settings will force the use of only JGit or a git executable, respectively:
useJGit
useReadableConsoleGit
These settings can be included in your project's git.sbt
or in
~/.sbt/1.0/git.sbt
-- for example, if no git executable is installed,
either file can have the following contents:
useJGit
Or you can set
the appropriate setting in the sbt prompt:
> set useReadableConsoleGit
[info] Reapplying settings...
[info] Set current project to scala-arm (in build file:...)
> session save
[info] Reapplying settings...
[info] Set current project to scala-arm (in build file:...)
Versioning with Git
You can begin to use git to control your project versions.
enablePlugins(GitVersioning)
The git plugin will now autogenerate your version using the following rules, in order:
- Looks at version-property setting (default to
project.version
), and checks thesys.props
to see if this has a value. If so, use it. - Otherwise, looks at the project tags. The first to match the
gitTagToVersionNumber
setting is used to assign the version. The default is to look for tags that begin withv
and a number, and use the number as the version. If there are multiple version tags, it will pick the highest. - If no tags are found either, look at the head commit. We attach this to the
git.baseVersion
setting: "<base-version>.<git commit sha>" - If no head commit is present either (which means this is a brand-new repository with no commits yet), we append the current timestamp to the base version: "<base-version>.<timestamp>".
The git.baseVersion
setting represents the in-development (upcoming) version you're working on.
You can alter the tag-detection algorithm using the git.gitTagToVersionNumber
setting. For example, if we wanted to alter the default version tag detection so it does not require a "v" at the start of tags, we could add the following setting:
git.gitTagToVersionNumber := { tag: String =>
if(tag matches "[0-9]+\\..*") Some(tag)
else None
}
You can turn on version detection using git describe
command by adding:
git.useGitDescribe := true
This way the version is derived by passing the result of git describe
to the gitTagToVersionNumber
function. The describe
version is built from the last tag + number of commits since tag + short hash. We recommend adopting the git describe approach.
You can enhance the git describe approach with glob
pattern matching, to match only relevant tags (as per git describe --match
functionality). This may be useful if, for example, your repository contains multiple types of tag.
git.gitDescribePatterns := Seq("module-name-*")
Additionally, you can also customize the version number generated by overriding one of the following keys:
git.formattedShaVersion
- Should look upgit.gitHeadCommit
key and generate a version based on it.git.formattedDateVersion
- The version we'll use if git is unavailable on this repository, for some reason.
As an example, you can alter the default sha-based versions using the following code
git.formattedShaVersion := git.gitHeadCommit.value map { sha => s"v$sha" }
Prompts
You can use the git plugin to add the project name + the current branch to your prompt. Simply add this setting to every project:
enablePlugins(GitBranchPrompt)
Usage
In an sbt prompt, simply enter any git command. e.g.
> git status
# On branch main
# Changes not staged for commit:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: build.sbt
# modified: project/plugins/project/Build.scala
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# src/site/
no changes added to commit (use "git add" and/or "git commit -a")
Known issues
When running sbt, you will see the following warnings in console:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
To get rid of them, you can force the SLF4J no-op binder by adding libraryDependencies += "org.slf4j" % "slf4j-nop" % "1.7.21"
to ~/.sbt/0.13/plugins/plugins.sbt
