如何使用scala + play + sbt复制资源

我正在使用sbt [0.13]使用scala [2.10.3]编译play [2.2]项目。我有用于数据库迁移的.sql文件和scala文件。目录结构如下所示:

app
|-> db
     |-> migration
           |-> V1__init.scala
           |-> V2__newTable.sql

当我从播放控制台(REPL)运行编译时,scala文件(V1__init.scala)被编译为.class并复制到classes文件夹。但是.sql文件没有被移动。

我尝试添加unmanagedResourceDirectories in Compile <++= baseDirectory { dir => Seq(dir/"app/db/migration") ++ Seq(dir/"db/migration") },但它没有复制文件。整个块看起来像:

val main = play.Project(appName, appVersion, appDependencies).settings(
    scalaVersion := "2.10.3",
    scalacOptions ++= Seq("-feature"),   // enable feature warnings
    unmanagedResourceDirectories in Compile <++=  baseDirectory { dir => Seq(dir/"app/db/migration") ++ Seq(dir/"db/migration") }
)

我也尝试使用copyResources,但无法使用它。这里描述:http://www.playframework.com/documentation/2.0/SBTSettings

那么有谁知道如何将sql文件复制到classes文件夹中?

谢谢!

更新

我有IO.copyDirectory(new java.io.File("app/db/migration"), new java.io.File("target/scala-2.10/classes/db/migration"), true)来复制文件,但目的地是硬编码的,并且会在我更新scala时更改

答案 0 :(得分:0)

  val main = play.Project(appName, appVersion, appDependencies).settings(
    scalaVersion := "2.10.3",
    scalacOptions ++= Seq("-feature"),   // enable feature warnings
    unmanagedResourceDirectories in Compile <+= scalaSource in Compile,
    excludeFilter in unmanagedResources in Compile := "*.scala" || "*.java"
  )

您可以使用以下命令轻松检查类文件夹中的内容:

 sbt clean full-classpath && ls target/scala-2.10/classes/db/migration/
