播放子项目无法编译 [英] Play sub-projects do not compile
问题描述
这是我的多项目Play 2.2应用程序的布局-我仍在尝试转换为build.sbt:
Here is the layout of my multi-project Play 2.2 application - I'm still trying to convert to build.sbt:
myApp
+ app
+ build.sbt
+ conf
| + routes
+ project
| + build.properties
| + Build.scala
| + plugin.sbt
+ modules
+ myModule
+ app
+ build.sbt
+ conf
+ routes
myApp/build.sbt:
myApp/build.sbt:
name := "myApp"
version := "1.0-SNAPSHOT"
organization := "com.mydomain"
lazy val myModule = project.in(file("modules/myModule"))
lazy val main = project.in(file(".")).dependsOn(myModule).aggregate(myModule)
play.Project.playScalaSettings
resolvers ++= Seq(
Resolvers.typesafe,
Resolvers.sonatype
)
myApp/projects/Build.scala:
myApp/projects/Build.scala:
import sbt._
object Resolvers {
val sonatype = Resolver.sonatypeRepo("snapshots")
val typesafe = "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
}
myApp/modules/myModule/build.sbt:
myApp/modules/myModule/build.sbt:
name := "myModule"
libraryDependencies ++= Seq(
"com.typesafe.play" %% "play" % "2.2.1" % "provided",
"org.reactivemongo" %% "reactivemongo" % "0.10.0-SNAPSHOT",
"org.reactivemongo" %% "play2-reactivemongo" % "0.10.0-SNAPSHOT"
)
resolvers ++= Seq(
Resolvers.typesafe,
Resolvers.sonatype
)
在尝试编译上面的项目时,我面临两个问题:
I'm facing with two problems when trying to compile the project above:
1)即使仅子项目具有依赖项(主项目只是许多子项目的容器),我也必须在主构建文件myApp/build.sbt
中指定resolvers
;如果我不这样做,该项目将无法编译.这不是一个阻塞性问题.但是我想了解原因.
1) Even if only the sub-project has dependencies (the main project is just a container for many sub-projects), I have to specify the resolvers
also in the main build file myApp/build.sbt
; if I don't, the project doesn't compile. This is not a blocking problem.. but I'd like to understand why.
2)然后,一旦我尝试编译项目,我总是会收到以下错误:
2) Then, as soon as I try to compile the project, I always get the following error:
[error] /home/j3d/Projects/myApp/conf/routes:9: not found: value myModule
[error] -> /myModule myModule.Routes
[error] /home/j3d/Projects/myApp/conf/routes: not found: value myModule
[error] /home/j3d/Projects/myApp/conf/routes:12: not found: value myModule
[error] GET /assets/*file controllers.Assets.at(path="/public", file)
[error] /home/j3d/Projects/myApp/conf/routes:9: not found: value handler
[error] -> /myModule myModule.Routes
[error] four errors found
[error] (main/compile:compile) Compilation failed
[error] Total time: 12 s, completed Dec 1, 2013 6:34:55 PM
这是myApp/conf/routes ...
Here is myApp/conf/routes...
GET / controllers.Application.index
-> /myModule myModule.Routes
GET /assets/*file controllers.Assets.at(path="/public", file)
...,最后是myApp/modules/myModule/conf/myModule.routes:
... and finally here is myApp/modules/myModule/conf/myModule.routes:
GET /myModule/greetings controllers.myModule.Greetings.hello
我想念什么吗?
推荐答案
弄清楚如何使其工作,下面是我的解决方案.首先,我为所有项目[myApp/project/Build.scala]定义了默认设置和解析器:
Figured out how to make it work and here below is my solution. First of all I've defined default settings and resolvers for all projects [myApp/project/Build.scala]:
import sbt._
import Keys._
object ApplicationBuild extends Build {
val defaultResolvers = Seq(
Resolver.sonatypeRepo("snapshots"),
"Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
)
val defaultSettings = Defaults.defaultSettings ++ Seq(
scalacOptions += "-language:reflectiveCalls",
resolvers ++= defaultResolvers
)
}
然后我刚刚将ApplicationBuild.defaultSettings
导入到每个build.sbt
中.这是主要的项目构建文件[myApp/build.sbt] ...
Then I've just imported ApplicationBuild.defaultSettings
into every build.sbt
. Here is the main project build file [myApp/build.sbt]...
name := "myApp"
version := "1.0-SNAPSHOT"
lazy val auth = project.in(file("modules/myModule"))
lazy val main = project.in(file(".")).dependsOn(myModule).aggregate(myModule)
ApplicationBuild.defaultSettings
playScalaSettings
...以及此处的子项目构建文件[myApp/modules/myModule/build.sbt]:
... and here the sub-project build file [myApp/modules/myModule/build.sbt]:
name := "myModule"
ApplicationBuild.defaultSettings
playScalaSettings
libraryDependencies ++= Seq(
"org.reactivemongo" %% "play2-reactivemongo" % "0.10.0-SNAPSHOT",
"org.reactivemongo" %% "reactivemongo" % "0.10.0-SNAPSHOT"
)
它可以正常工作,希望对您有所帮助;-)
It just works and hope it helps ;-)
