【问题描述】:
我尝试从 play 2.1.1 迁移 Java play 框架项目。到 2.2.0。我遵循了迁移指南 (https://www.playframework.com/documentation/2.2.0/Migration22),但在应用更改后出现以下编译错误:
.../Global.java:38: cannot find symbol
symbol : method schedule(scala.concurrent.duration.FiniteDuration,
scala.concurrent.duration.FiniteDuration,akka.actor.ActorRef,
parser.ParserActor.MensaName,scala.concurrent.ExecutionContext)
location: interface akka.actor.Scheduler
.schedule(Duration.create(diff, TimeUnit.MILLISECONDS),
^
.../controllers/Parsers.java:24: cannot find symbol
symbol : method scheduleOnce(scala.concurrent.duration.FiniteDuration,akka.actor.ActorRef,parser.ParserActor.MensaName,scala.concurrent.ExecutionContext)
location: interface akka.actor.Scheduler
.scheduleOnce(Duration.create(0, TimeUnit.SECONDS),
^

2 errors
(compile:compile) javac returned nonzero exit code
我尝试用 typesafe-activator 和 play 命令编译它,都不起作用。当我使用旧的播放版本时,编译适用于这两种工具。
我想我在某些地方缺少依赖项。例如。自新版本以来,我是否必须手动将 Akka 添加到依赖项中?还是我监督了其他一些常见错误?
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" % "2.2.0")
build.properties
sbt.version=0.13.0
构建.scala
import sbt._
import Keys._
import play.Project._
object ApplicationBuild extends Build {
val appName = "mensa-server"
val appVersion = "1.0-SNAPSHOT"
val appDependencies = Seq(
// Add your project dependencies here,
javaCore,
javaJdbc,
javaEbean,
"org.jsoup" % "jsoup" % "1.7.2",
"net.sf.flexjson" % "flexjson" % "3.0",
"postgresql" % "postgresql" % "9.1-901.jdbc4",
"org.apache.commons" % "commons-lang3" % "3.1",
"com.typesafe" %% "play-plugins-mailer" % "2.1.0",
"org.apache.pdfbox" % "pdfbox" % "1.8.2"
)
val main = play.Project(appName, appVersion, appDependencies).settings(
// Add your own project settings here
)
}
