下面是我的多项目结构:
myApp
+ build.sbt
+ sub-prj-1
+ build.sbt
+ sub-prj-2
+ build.sbt
+ project
+ Build.scala
我用来在 project/Build.scala
中定义通用设置,如下所示:
import sbt._
import Keys._
object ApplicationBuild extends Build {
val defaultScalacOptions = Seq(
"-unchecked", "-deprecation", "-feature", "-language:reflectiveCalls", "-language:implicitConversions",
"-language:postfixOps", "-language:dynamics", "-language:higherKinds", "-language:existentials",
"-language:experimental.macros", "-encoding", "UTF-8", "-Xmax-classfile-name", "140")
val defaultResolvers = Seq(
"Typesafe releases repository" at "http://repo.typesafe.com/typesafe/releases/"
)
val defaultSettings = Defaults.defaultSettings ++ Seq(
scalaVersion := "2.10.4",
scalacOptions ++= defaultScalacOptions,
resolvers ++= defaultResolvers
)
}
... 然后我在每个 build.sbt
文件中引用这些通用设置:
name := "myapp"
organization := "Test, Inc."
version := "1.0"
ApplicationBuild.defaultSettings // it looks like common settings defined in
// project/Build.scala are not read...
scalacOptions += "-feature" // already defined in ApplicationBuild.defaultSettings...
// but if I don't define it here, it doesn't work
lazy val `sub-prj-1` = project.in(file("sub-prj-1"))
lazy val `sub-prj-2` = project.in(file("sub-prj-2"))
lazy val brix = project.in(file(".")).settings(
publishArtifact := false
).aggregate(
`sub-prj-1`,
`sub-prj-2`
)
例如,scalacOptions += "-feature"
已经在 Build.scala
中定义了...但是如果我没有在 build 中定义它.sbt
我总是收到以下警告:
[warn] there were 1 deprecation warning(s); re-run with -deprecation for details
[warn] one warning found
有什么想法吗?我错过了什么吗?这个问题是我安装sbt 0.13.5后第一次出现的。
编辑
这是scalacOptions
的内容:
[info] sub-prj-1/*:scalacOptions
[info] List(-unchecked, -deprecation, -feature, -language:reflectiveCalls, -language:implicitConversions, -language:postfixOps, -language:dynamics, -language:higherKinds, -language:existentials, -language:experimental.macros, -encoding, UTF-8, -Xmax-classfile-name, 140)
[info] sub-prj-2/*:scalacOptions
[info] List(-unchecked, -deprecation, -feature, -language:reflectiveCalls, -language:implicitConversions, -language:postfixOps, -language:dynamics, -language:higherKinds, -language:existentials, -language:experimental.macros, -encoding, UTF-8, -Xmax-classfile-name, 140)
[info] myapp/*:scalacOptions
[info] List(-unchecked, -deprecation, -feature, -language:reflectiveCalls, -language:implicitConversions, -language:postfixOps, -language:dynamics, -language:higherKinds, -language:existentials, -language:experimental.macros, -encoding, UTF-8, -Xmax-classfile-name, 140)
最佳答案
我只能猜测(并指望在错误时纠正其他信息),但 warn
消息来自构建项目(在 project
下)而不是你的。
我使用的是 sbt 0.13.6-SNAPSHOT(今天从源代码构建)所以你的里程可能会有所不同。
➜ myApp xsbt

[info] Loading project definition from /Users/jacek/sandbox/common-settings/myApp/project

[warn] one warning found

当我尝试重现您的案例时,我最终得到了 project
下构建定义的消息:
[warn] there were 1 deprecation warning(s); re-run with -deprecation for details
[warn] one warning found
它们是您想要摆脱的东西吗?如果是这样,请继续阅读。否则向您的问题添加其他信息。谢谢。
对于 sbt is recursive ,project
下的是另一个构建定义(等等)。
为了摆脱这些消息,您应该听从他们的建议并在相应项目的构建定义中添加-deprecation
。将以下内容添加到 project/build.sbt:
scalacOptions += "-deprecation"
有了这个,重新加载
,谜团就揭开了。

要解决这个问题,应该阅读文章 Preview of upcoming sbt 1.0 features: Read about the new plugins .
关于scala - 为什么 sbt 一直告诉我添加 -deprecation 到 scalacOptions ?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/24223839/
