Question

我想用Play Framework 2.5构建一个多应用程序项目，但我不明白为什么项目的一部分从未编译

这是项目的结构：

build.sbt (main sbt file)
common/ (common code shared by apps)
     build.sbt
     app/
     conf/
     public/
apps/
     app1/
         build.sbt
         app/
         conf/
         public/
     app2/
         build.sbt
         app/
         conf/
         public/
     ...

common/和appX/是具有自己的build.sbt文件的Play Framework应用。

主要build.sbt文件：

lazy val common = (project in file("common"))

lazy val app1 = (project in file("apps/app1"))

lazy val app2 = (project in file("apps/app2"))

lazy val root = (project in file("."))
  .dependsOn(common, app1, app2)
  .aggregate(common, app1, app2)

常见的build.sbt文件：

import WebJs._
import RjsKeys._

scalaVersion := "2.11.11"

lazy val common = (project in file("."))
  .enablePlugins(PlayJava, PlayEbean, SbtWeb)

// Add dependencies from Maven
libraryDependencies ++= Seq(
  filters,
  javaCore,
  javaJdbc,
  cache,
  javaWs
)

// Enable JavaScript uglifying
pipelineStages := Seq(rjs, uglify, digest)

// Enable CSS optimization
buildProfile := JS.Object("optimizeCss" -> "standard")

// Disable strange behavior in local run
fork in run := false

// Configure the Eclipse project as a Java project
EclipseKeys.projectFlavor := EclipseProjectFlavor.Java
EclipseKeys.createSrc := EclipseCreateSrc.ValueSet(EclipseCreateSrc.ManagedClasses, EclipseCreateSrc.ManagedResources)
EclipseKeys.preTasks := Seq(compile in Compile)

// Remove eviction warnings
evictionWarningOptions in update := EvictionWarningOptions.default.withWarnTransitiveEvictions(false)

app1 build.sbt文件：

name := """app1"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.11"

lazy val common = (project in file("../../common"))
lazy val app1 = (project in file("."))
  .enablePlugins(PlayJava)
  .dependsOn(common)

app2 build.sbt文件：

name := """app2"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.11"

lazy val common = (project in file("../../common"))
lazy val app2 = (project in file("."))
  .enablePlugins(PlayJava)
  .dependsOn(common)

等

通常，我具有通用源代码的路由（例如：用户控制器），并且每个应用程序都有一个路由文件。

当我尝试使用sbt compile进行编译时，我得到以下输出：

我的结构部分基于以下项目：https://github.com/josh-padnick/play-multiproject-template和SBT文档：https://www.scala-sbt.org/1.x/docs/Multi-Project.html 通用应用程序根本无法编译。为什么？这是实现我目标的好方法吗？

谢谢。

编辑： 如果我做sbt; project common; compile，则什么也没发生：

[info] Updating {file:/myProject/}common...
[info] Resolving jline#jline;2.14.3 ...
[info] Done updating.

我通过在主要sbt文件中移动enablePlugins来解决此问题：

lazy val common = (project in file("common"))
  .enablePlugins(PlayJava, PlayEbean, SbtWeb)

lazy val app1 = (project in file("apps/app1"))
  .enablePlugins(PlayJava)
  .dependsOn(common)

lazy val app2 = (project in file("apps/app2"))
  .enablePlugins(PlayJava)
  .dependsOn(common)

lazy val root = (project in file("."))
  .dependsOn(common, app1, app2)
  .aggregate(common, app1, app2)

带有Play Framework 2.5的多应用项目
