scala无法将带有java项目的Play框架打包到war中

Question

大家好，我正在尝试在AWS EC2实例上部署我的应用程序。为此，我让tomcat服务器在那里运行。我想从这个游戏项目中创建一个war文件。eclipse中没有显示任何错误。我的项目目录是play userReg：

C:\playdemo>play war play-userReg -o myapp.war
~        _            _
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/
~
~ play! 1.3.x-1.3.0RC1, http://www.playframework.org

我的身材。sbt文件是：

name := """play-userReg"""

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
    "com.typesafe.play" %% "play" % "2.3.0" % "provided",
    "org.springframework" % "spring-core" % "3.2.2.RELEASE",
    "org.springframework" % "spring-context" % "3.2.2.RELEASE",
    "org.mongodb" % "mongo-java-driver" % "2.11.0",
    "org.springframework.data" % "spring-data-mongodb" % "1.2.0.RELEASE",
    "cglib" % "cglib" % "2.2.2",
    javaCore,
    javaJdbc,
    javaEbean
)

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

看起来你正试图用Play 1构建一个Play 2项目

你应该运行“激活器”而不是“播放”
