SBT项目定义文件的弃用和功能警告

编译SBT项目定义（即

项目

目录中的文件）时，我收到了弃用和功能警告。SBT版本为0.13.0

通过设置

scalacOptions:=Seq（“-feature”，“-deprecation”）

，我无法获得关于这些的更多信息，这似乎只适用于项目源文件，而不适用于项目定义文件

有人知道我如何在编译器编译项目定义时为它设置弃用和警告吗

[info] Loading project definition from /home/xxx/website/project
[warn] there were 2 deprecation warning(s); re-run with -deprecation for details
[warn] there were 4 feature warning(s); re-run with -feature for details
[warn] two warnings found

---

创建具有以下内容的

project/build.sbt

项目定义文件：

scalacOptions := Seq("-feature", "-deprecation")

由于

project

下的任何

*.sbt

文件都属于元（构建）项目，因此它为构建配置而不是构建中项目的环境设置Scala编译器

使用sbt多项目样本进行了测试：

[info] Compiling 1 Scala source to /Users/jacek/sandbox/so/multi-0.13.1/project/target/scala-2.10/sbt-0.13/classes...
[warn] /Users/jacek/sandbox/so/multi-0.13.1/project/Build.scala:4: method error in object Predef is deprecated: Use `sys.error(message)` instead
[warn]   lazy val e = error("Launcher did not provide the Ivy home directory.")
[warn]                ^
[warn] one warning found

…当它编译以下

项目/Build.scala

时：

import sbt._

object Build extends Build {
  lazy val e = error("Launcher did not provide the Ivy home directory.")
}
