TwirlCompiler NullPointerException on Win7. #175

Open jccode opened 6 years ago

jccode commented 6 years ago

I write a extremely simple demo, which works well on my OSX. When I run it on Win7, it gives me a NPE. I don't know where I'm doing wrong or it's a bug on Windows.

plugins.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.6.12")

build.sbt

name := "play-demo1"

version := "0.1"

scalaVersion := "2.12.5"

lazy val `play-demo1` = (project in file(".")).enablePlugins(PlayScala)

libraryDependencies ++= Seq(
  guice, specs2 % Test,
  "org.webjars" % "bootstrap" % "4.0.0-2"
)

The demo I used is accessable via: https://github.com/jccode/play-demo1

Error trace as belows:
