Scala 将play2 elasticsearch模块与play2.2.1一起使用时出错，

我正在尝试将play2 elasticsearch模块与scala中的play2.2.1一起使用。My Build.scala看起来像：

object ApplicationBuild extends Build {

val appName         = "play-elastic"
val appVersion      = "1.0-SNAPSHOT"

val appDependencies = Seq(
    "com.clever-age" % "play2-elasticsearch" % "0.8-SNAPSHOT" 
)

val main = play.Project(appName, appVersion, appDependencies).settings(
    resolvers += Resolver.url("play-plugin-releases", new URL("http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns),
    resolvers += Resolver.url("play-plugin-snapshots", new URL("http://repo.scala-sbt.org/scalasbt/sbt-plugin-snapshots/"))(Resolver.ivyStylePatterns)
)
}

play.plugins：

9000:com.github.cleverage.elasticsearch.plugin.IndexPlugin

在application.conf的末尾添加了以下内容

elasticsearch.local=false
elasticsearch.client="127.0.0.1:9300"
elasticsearch.index.name="play2-elasticsearch"
elasticsearch.index.settings="{ analysis: { analyzer: { my_analyzer: { type: \"custom\",      tokenizer: \"standard\" } } } }"
elasticsearch.index.clazzs="indexing.*"
elasticsearch.index.show_request=true

我使用了示例scala弹性搜索示例，并将代码添加到Application.scala中的index方法中。我第一次访问应用程序时出现以下错误：

Caused by: java.lang.NullPointerException: null

任何帮助都将不胜感激

你能发布你的Application.scala文件吗？如前所述，我使用的是示例中给出的文件，你仍然有这个错误吗？我刚刚试着启动这个示例，它运行得很好（我只需要在

project/build.properties

和

project/plugins.sbt

中调整play和sbt版本）。
