由于WebJarAssets资源初始化失败，我在运行应用程序时遇到NoSuchMethodError有点问题。 我希望在我的scala.html文件
中使用如下的WebJarAssets<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("react", "react.js"))'></script>
<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("react", "react-dom.js"))'></script>
<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.fullPath("jquery", "jquery.js"))'></script>
我的build.sbt如下
name := "myApp"
version := "1.0"
lazy val root = (project in file(".")).enablePlugins(PlayJava, SbtWeb, PlayEbean)
scalaVersion := "2.11.8"
JsEngineKeys.engineType := JsEngineKeys.EngineType.Node

)
resolvers += Resolver.url("Typesafe Ivy releases", url("https://repo.typesafe.com/typesafe/ivy-releases"))(Resolver.ivyStylePatterns)
fork in run := false
如您所见，我尝试过几个不同的webjar库 我的应用程序的plugin.sbt如下
// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.12")
// Web plugins
addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.4")
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.8")
addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.1.1")
addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")

//addSbtPlugin("com.github.stonexx.sbt" % "sbt-babeljs" % "1.0.5")
// Play enhancer - this automatically generates getters/setters for public fields
// and rewrites accessors of these fields to use the getters/setters. Remove this
// plugin if you prefer not to have this feature, or disable on a per project
// basis using disablePlugins(PlayEnhancer) in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")
// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using
// enablePlugins(PlayEbean).
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "4.0.0-M2")
//sbt plugin for eclipse
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.1.0")
运行应用程序后，我得到以下堆栈跟踪

任何有关可能导致此问题的见解都会非常有用。
答案 0 :(得分：1)
您正在使用Play 2.5，因此请使用以下依赖项：
"org.webjars" %% "webjars-play" % "2.5.0-4"
并确保您已定义路线：
GET /assets/*file controllers.Assets.at(path="/public", file)
