我可以从代码中访问我的 Scala 应用程序的名称和版本(在 SBT 中设置)吗? [英] Can I access my Scala app's name and version (as set in SBT) from code?
问题描述
我正在使用 SBT (0.11.0) 使用 Scala 构建定义构建一个应用程序,如下所示:
I am building an app with SBT (0.11.0) using a Scala build definition like so:
object MyAppBuild extends Build {
import Dependencies._
lazy val basicSettings = Seq[Setting[_]](
organization := "com.my",
version := "0.1",
description := "Blah",
scalaVersion := "2.9.1",
scalacOptions := Seq("-deprecation", "-encoding", "utf8"),
resolvers ++= Dependencies.resolutionRepos
)
lazy val myAppProject = Project("my-app-name", file("."))
.settings(basicSettings: _*)
[...]
我将在过程结束时打包一个 .jar.
I'm packaging a .jar at the end of the process.
我的问题很简单:有没有办法从我的 Scala 代码中以编程方式访问应用程序的名称(my-app-name")和版本(0.1")?如果可以的话,我不想在两个地方重复它们.
My question is a simple one: is there a way of accessing the application's name ("my-app-name") and version ("0.1") programmatically from my Scala code? I don't want to repeat them in two places if I can help it.
非常感谢任何指导!
推荐答案
sbt-buildinfo
我刚刚写了 sbt-buildinfo.安装插件后:
lazy val root = (project in file(".")).
enablePlugins(BuildInfoPlugin).
settings(
buildInfoKeys := Seq[BuildInfoKey](name, version, scalaVersion, sbtVersion),
buildInfoPackage := "foo"
)
以上代码段已更新以反映 sbt-buildinfo 的更新版本.
The above snippet has been updated to reflect more recent version of sbt-buildinfo.
它通过自定义 buildInfoKeys
生成具有您想要的任何设置的 foo.BuildInfo
对象.
It generates foo.BuildInfo
object with any setting you want by customizing buildInfoKeys
.
我一直想为此制作一个插件,(我写了它)但这里有一个生成文件的快速脚本:
I've been meaning to make a plugin for this, (I wrote it) but here's a quick script to generate a file:
sourceGenerators in Compile <+= (sourceManaged in Compile, version, name) map { (d, v, n) =>
val file = d / "info.scala"
IO.write(file, """package foo
|object Info {
| val version = "%s"
| val name = "%s"
|}
|""".stripMargin.format(v, n))
Seq(file)
}
您可以通过 foo.Info.version
获取您的版本.
You can get your version as foo.Info.version
.
