eclipse - 调试不适用于 play 框架激活器、scala 和 eclipse

Question

有很多关于此的帖子，说明很简单，但在我的一生中，我无法让调试器在断点处停止。

我的环境是

eclipse 4.4.1

斯卡拉 2.11

Scala IDE 4.1.0.nightly

Play Framework 2.3.3

在 Scala IDE 0.4.6 中 Play 支持

我按如下方式启动激活器

activator -jvm-debug 9999 run

我已经设置了一个带有标准套接字连接的远程 Java 应用程序调试配置。调试配置运行，附加到远程并启动一堆 sbt 线程。

但是，它不会在调试器中停止!看起来并不难，我做错了什么？

编辑:
我在一个我已经工作了一段时间的项目和一个全新的、未受影响的 play-anguale-require-seed 项目实例中遇到了这个问题。这是该项目的 build.sbt:

import WebKeys._

// TODO Replace with your project's/module's name
name := """play-angular-require-seed"""

// TODO Set your organization here; ThisBuild means it will apply to all sub-    modules
organization in ThisBuild := "your.organization"

// TODO Set your version here
version := "2.3.7-SNAPSHOT"

// Scala Version, Play supports both 2.10 and 2.11
//scalaVersion := "2.10.4"
scalaVersion := "2.11.4"

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

// Dependencies
libraryDependencies ++= Seq(
  filters,
  cache,

)

fork in run := true

克里斯的评论有答案!从 build.sbt 中删除 fork in run 或将其设置为 false。我不确定是否会有下游后果。
