Scala 生成版本时SBT编译时间慢

scala playframework sbt

Scala 生成版本时SBT编译时间慢,scala,playframework,sbt,Scala,Playframework,Sbt,我有一个多模块播放（scala）项目 Scala版本2.11.7 SBT版本0.13.8 项目看起来是这样的，非常简单，build.sbt lazy val root = project.in(file(".")) .aggregate(lib1, lib2, lib3, lib4, web) .settings(scalaVersion := "2.11.7") lazy val lib1 = Project( "lib1", file("libs/lib1") )

我有一个多模块播放（scala）项目

Scala版本2.11.7

SBT版本0.13.8

项目看起来是这样的，非常简单，build.sbt

lazy val root = project.in(file("."))
    .aggregate(lib1, lib2, lib3, lib4, web)
    .settings(scalaVersion := "2.11.7")

lazy val lib1 = Project( "lib1", file("libs/lib1") )
    .settings(
        name := "lib1",
        version := "0.0.1-SNAPSHOT"
    )

lazy val lib2 = Project( "lib2", file("libs/lib2") )
    .settings(
        name := "lib2",
        version := "0.0.1-SNAPSHOT"
    )

lazy val lib3 = Project( "lib3", file("libs/lib3") )
    .dependsOn(lib1)
    .settings(
        name := "lib3",
        version := "0.0.1-SNAPSHOT"
    )

lazy val lib4 = Project( "lib4", file("libs/lib4") )
    .dependsOn(lib1, lib2)
    .settings(
        name := "lib4",
        version := "0.0.1-SNAPSHOT"
    )

// Play framework (2.4.0)
lazy val web = Project( "web", file("modules/web") )
    .dependsOn(lib4, lib3)
    .settings(
        name := "web",
        version := "0.0.1-SNAPSHOT"
    )

当我想要发布这个项目时，我首先将所有子模块版本更新为非快照版本

我遇到的问题是当我做一件事时；清洁的从项目的根目录开始编译需要很长时间（web模块相当大）。但是，如果我从除modules/web/build.sbt之外的所有版本中删除-SNAPSHOT部分，编译时间就会短得多

当我在web模块中删除版本的-SNAPSHOT部分时，为什么编译需要更长的时间

更新

我在Wercker中浏览了构建历史，我注意到每次构建发行版（非快照版本）时，编译所需的时间都要长得多。我现在对此作出反应的原因是，由于项目不断发展，我最终在Wercker达到了超时限制

更新2

我使用以下命令对使用快照版本和不使用快照版本的编译进行了分析：在ThisBuild++=Seq（“-ystatics”）中设置scalacOptions

每次测试前，我都会：

sbt
> ;clean;cleanFiles;update
> set scalacOptions in ThisBuild ++= Seq("-Ystatistics")
> compile

测试1，子模块
web
，版本为0.0.1-SNAPSHOT
