在Play Framework 2.3.0(Java)的build.sbt中定义JAVA_OPTS

我正在尝试在build.scala中定义JAVA_OPTS,以便为运行和测试任务指定调试端口和配置文件,但是它不起作用.我启动激活器,然后运行或测试.
这是我的build.sbt：

name := "machinchose"

version := "1.0-SNAPSHOT"

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

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  javaJdbc,
  javaEbean,
  cache,
  javaWs
)

Keys.fork in run := true

javaOptions in run ++= Seq(
    "-Xdebug",
    "-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9997",
    "-Dconfig.file=conf/developpement.conf",
    "-Xms128m",
    "-Xmx1024m"
)

Keys.fork in Test := true

javaOptions in Test ++= Seq(
    "-Xdebug",
    "-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9997",
    "-Dconfig.file=conf/test.conf",
    "-Xms128m",
    "-Xmx1024m"
)

我搞砸了什么？谢谢你的帮助.

解决方法:

Play并不真正支持分叉.可能只是忽略了该设置.因此,由于没有新的JVM,您的javaOptions将无法工作.您要做的就是使用这些选项启动激活器(或sbt)本身,或者设置环境变量JAVA_OPTS,SBT_OPTS或ACTIVATOR_OPTS之一.还有一个-jvm-debug到激活器以添加调试器.
