我在使用Scala的Play2应用程序中遇到意外异常。与this问题
中提到的错误相同这是我在浏览器中获得的内容:
scala.MatchError:java.lang.StackOverflowError(类 java.lang.StackOverflowError的) play.PlayReload $$ anonfun $ taskFailureHandler $ 1.适用(PlayReload.scala:44) play.PlayReload $$ anonfun $ taskFailureHandler $ 1.适用(PlayReload.scala:44) scala.Option.map(Option.scala:145) play.PlayReload $ .taskFailureHandler(PlayReload.scala:44) play.PlayReload $ .compileFailure(PlayReload.scala:40) play.PlayReload $$ anonfun $编译$ 1.适用(PlayReload.scala:17) play.PlayReload $$ anonfun $编译$ 1.适用(PlayReload.scala:17) scala.util.Either $ LeftProjection.map(Either.scala:377) play.PlayReload $ .compile(PlayReload.scala:17)
我的堆栈跟踪非常大。其中一部分如下:
scala.tools.nsc.typechecker.Typers $ $ Typer.scala工具$ $ NSC $ typechecker $ Typers $$打字员typedInternal(Typers.scala:5332) 在scala.tools.nsc.typechecker.Typers $ Typer.body $ 2(Typers.scala:5279) 在scala.tools.nsc.typechecker.Typers $ Typer.typed(Typers.scala:5283) 在 scala.tools.nsc.typechecker.Typers $打字员$$ anonfun $ 93.apply(Typers.scala:4440) [error](编译:编译)java.lang.StackOverflowError [错误] 申请 -

我已经尝试了更改堆和堆栈大小的答案但是当我运行jconsole时它显示它不起作用。
我还尝试从this链接更改其堆大小,但它也无法正常工作,我仍然遇到同样的错误。
这是我的build.sbt文件:
name := """myproject"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayScala)
scalaVersion := "2.11.1"
fork in run := true
javaOptions in run ++= Seq(
"-Xms1G", "-Xmx2G", "-XX:MaxPermSize=1024M", "-XX:+UseConcMarkSweepGC")
//SBT_OPTS=-Xss8m
//JAVA_OPTS="-Xms512m "
//val buildSettings = Defaults.defaultSettings ++ Seq( javaOptions += "-Xms1G -Xmx2G"
//)
libraryDependencies ++= Seq("org.scalatest" %% "scalatest" % "2.2.1" % "test"withSources() withJavadoc(),
"com.esotericsoftware.kryo" % "kryo" % "2.10",
"org.mongodb" %% "casbah" % "2.8.0",
"org.slf4j" % "slf4j-api" % "1.6.4",
"org.elasticsearch" % "elasticsearch" % "1.5.0",

"ch.qos.logback" % "logback-core" % "1.0.9",
"ch.qos.logback" % "logback-classic" % "1.0.9"
)
请指导我。

更改堆栈大小对我有用
我用这个命令来运行项目
激活器运行-J-Xss4M -server
