Java 使用activator启动播放服务器时抛出application.conf not found错误

我有一个很奇怪的问题

我正在用play 2.3创建一个服务器。当我使用

activator run

启动它时，它工作得非常好。但是如果我使用

activator start

在部署模式下启动服务器，我会得到一个IOException:file not found for application.conf

Configuration error: Configuration error[application: application.conf: java.io.IOException: resource not found on classpath: application.conf, application.json: java.io.IOException: resource not found on classpath: application.json, application.properties: java.io.IOException: resource not found on classpath: application.properties]

当我运行activator windows:packageBin时，它会对退出的库发出警告：

[warn] There may be incompatibilities among your library dependencies.
[warn] Here are some of the libraries that were evicted:
[warn]  * com.typesafe.sbt:sbt-native-packager:0.7.4 -> 1.0.3
[warn] Run 'evicted' to see detailed eviction warnings

奇怪的是它几个月前就开始工作了

这是我的build.sbt文件：

name := """IdTabDriver"""
version := "1.0.0.1"

name in Windows := "IdTabDriver"

//packageSummary in Windows := "IdTabDriver"

//packageDescription in Windows := "IdTabDriver"

maintainer in Windows := "Access France"

organization := "Access France"

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

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  cache,
  javaWs,
  "commons-configuration" % "commons-configuration" % "1.10",
  "org.rxtx" % "rxtxcomm" % "2.0-7pre1"
)

resolvers += "Typesafe repository" at "https://repo.typesafe.com/typesafe/releases/"

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.8")

addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.3")

和我的plugin.sbt文件：

name := """IdTabDriver"""
version := "1.0.0.1"

name in Windows := "IdTabDriver"

//packageSummary in Windows := "IdTabDriver"

//packageDescription in Windows := "IdTabDriver"

maintainer in Windows := "Access France"

organization := "Access France"

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

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  cache,
  javaWs,
  "commons-configuration" % "commons-configuration" % "1.10",
  "org.rxtx" % "rxtxcomm" % "2.0-7pre1"
)

resolvers += "Typesafe repository" at "https://repo.typesafe.com/typesafe/releases/"

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.8")

addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.3")

编辑：我使用了

-Dconfig.file=conf/application.conf

选项来解决以前的异常，但是我得到了一个新的异常

Configuration error: Configuration error[Cannot initialize the custom Global object (controllers.Global) (perhaps it's a wrong reference?)]

你的问题是众所周知的

PlayFramework2.3.x并没有一直使用自动插件。当您混合使用AutoPlugin（sbt native packager 1.0.3）和非AutoPlugin构建（如play 2.3.x）时，这会导致奇怪的问题

此外，您正在使用JavaAppPackaging原型，但play已经启用了JavaServerAppPackaging原型。这也可能导致一些像你这样的奇怪行为

所以解决办法是

• 将play 2.3.x升级到2.4.x
• 或将sbt本机打包机降级为0.8.x

您还可以查看

如果您告诉activator像使用

-Dconfig.file=conf/application.conf

那样明确地使用此配置文件，会发生什么情况？@Kris编辑了这个问题，结果是我害怕这种问题。。。我无法升级到Play2.4，因为我没有Java8。。。我不知道你是否可以用sbt native packager 0.8制作windows installer？windows installer也可以用0.8.0制作。但是我不知道如何自定义配置文件？似乎无法导出添加的文件（证书）。文档可在此处找到：
