Question

我最近在migration guide之后从版本2.2.x升级到Play Framework 2.3.6（Java版本）。在本地，我的应用程序按预期工作，但在部署到Heroku时，/assets/缺少javascripts和样式表。我的javascripts位于public/javascripts/，我的样式表是从app/assets/stylesheets/中的LESS文件生成的。

切换到Play Framework 2.3.x后，plugins.sbt和build.sbt都发生了很大的变化，所以我在下面都包含了这两个内容。也许错误在那里可以找到？

我的plugins.sbt：

// Comment to get more information during initialization
logLevel := Level.Warn

// The Typesafe repository
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.6")

// Use LESS
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.0.4")

// Use JSHint to validate javascript
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.1")

// Use RequireJS to (among other things) minify javascript
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.5")

addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.0.0")

addSbtPlugin("com.typesafe.sbt" % "sbt-gzip" % "1.0.0")

addSbtPlugin("com.typesafe.sbt" % "sbt-uglify" % "1.0.3")

我的build.sbt：

import com.typesafe.sbt.less.Import.LessKeys
import play.PlayJava

name := "myApp"

version := "1.0-SNAPSHOT"

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

pipelineStages := Seq(rjs, digest, gzip)

scalaVersion := "2.11.1"

val appName = "myApp"
val appVersion = "1.0-SNAPSHOT"

javaOptions ++= Seq("-Xms128m", "-Xmx384m", "-Xss512k", "-XX:+UseCompressedOops")

)

includeFilter in (Assets, LessKeys.less) := "*.less"

excludeFilter in (Assets, LessKeys.less) := "_*.less"

LessKeys.compress in Assets := true

dependencyOverrides += "org.avaje.ebeanorm" % "avaje-ebeanorm" % "3.3.3"

dependencyOverrides += "org.avaje.ebeanorm" % "avaje-ebeanorm-agent" % "3.2.2"

    Resolver.url("Objectify Play Repository", url("http://deadbolt.ws/releases/"))(Resolver.ivyStylePatterns),
    Resolver.url("Objectify Play Snapshot Repository", url("http://schaloner.github.com/snapshots/"))(Resolver.ivyStylePatterns),
    "play-easymail (release)" at "http://joscha.github.com/play-easymail/repo/releases/",

Answer 1

将pipelineStages := Seq(rjs, digest, gzip)替换为pipelineStages := Seq(uglify, digest, gzip)。不知道为什么会这样，但它对我有用。
