SBT 可以刷新 git uri 依赖项(总是或按需)? [英] Can SBT refresh git uri dependency (always or on demand)?

问题描述

我有以下 sbt 代码来添加对 git uri 的插件依赖:

I have the following sbt code to add a plugin dependency on a git uri:

import sbt._

object Plugins extends Build {
  lazy val username = ("git config --global user.bitbucket" !!).trim

  lazy val root = Project("root", file(".")) dependsOn(
    uri(s"https://$[e-mail]/team/build.git#build_0.1")
  )
}

这很好，但是我发现如果我对 build_0.1 进行更改并推送它，当我再次 compile 项目时，sbt 不会拉我所做的更改，所以我有一个过时的插件.

This works fine, but I find that if I make changes to build_0.1 and push it, when I come to compile the project again, sbt does not pull the changes I've made so I have an out of date plugin.

如何让 SBT 始终对它所依赖的依赖项执行 git pull?

How can I get SBT to always do a git pull on the dependencies it depends on?

推荐答案

SBT 最高 0.13.2-M1 支持 git clone 和 git checkout 仅.

SBT up to 0.13.2-M1 supports git clone and git checkout only.

git clone 用于当 URL 不包含 # 以指向分支或提交时，例如

git clone is used when the URL doesn't contain # to point at a branch or a commit, e.g.

git:file:///Users/jacek/sandbox/so/sbt-git/git-repo

git checkout 在 URL 中有 # 指向分支或提交时执行，例如

git checkout is executed when the URL has # in the URL that points at a branch or a commit, e.g.

git:file:///Users/jacek/sandbox/so/sbt-git/git-repo/#a221379c7f82e5cc089cbf9347d473ef58255bb2

当我 commit 对 git 存储库进行更改时，我还必须更新 build.sbt 中的提交哈希，以便在SBT 项目(下面的 val v).

When I commit'ed a change to a git repo, I had to update the commit hash in build.sbt, too, to have the change referenced in the SBT project (the val v below).

lazy val v = "a221379c7f82e5cc089cbf9347d473ef58255bb2"

lazy val g = RootProject(uri(s"git:file:///Users/jacek/sandbox/so/sbt-git/git-repo/#$v"))

lazy val root = project in file(".") dependsOn g

随着 git 存储库中的更改，必须对 SBT 项目进行重新加载，以便可以运行新的签出并刷新项目.

With changes in the git repository, the SBT project has to be reload'ed so a new checkout can be run and the project gets refreshed.

[root]> reload
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Loading project definition from /Users/jacek/sandbox/so/sbt-git/project
Cloning into '/Users/jacek/.sbt/0.13/staging/24535507588417c1c2dc/git-repo'...
Checking connectivity... done
[info] Set current project to root (in build file:/Users/jacek/sandbox/so/sbt-git/)
[root]>

这很痛苦，但可以解决问题(并让您使用远程 git 存储库跟踪您的位置).

It's painful, but does the trick (and let you track where you are with the remote git repo).

您可能还会发现 GIT 中的多项目可以用作 SBT 依赖项吗? 很有用.
