由于我渴望在我的 Play 2 项目中使用 Elastic Search，我已经阅读了 http://www.elasticsearch.org/guide/reference/java-api/并添加了依赖项：

构建.scala：

import sbt._
import Keys._
import PlayProject._

object ApplicationBuild extends Build {

    val appName         = "test"
    val appVersion      = "1.0-SNAPSHOT"

    val appDependencies = Seq(
      // Add your project dependencies here,
      "mysql" % "mysql-connector-java" % "5.1.18",      
      "org.elasticsearch" % "elasticsearch" % "0.19.10"
    )

    val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(
      // Add your own project settings here
      resolvers += Resolver.url("GitHub Play2-elasticsearch Repository", url("http://cleverage.github.com/play2-elasticsearch/releases/"))(Resolver.ivyStylePatterns)      
    )
}

找到并下载依赖项，检查播放依赖项：

Here are the resolved dependencies of your application:

但是在eclipse中我不能使用elasticsearch，因为它找不到库。我什至无法导入它。

我在这里想念什么？

添加新依赖项后（即更新文件后） ，您必须eclipsify在 Play 控制台中重做。Build.scala

它将.classpath为 Eclipse 生成一个包含新依赖项的新文件。

如果 Build.scala 设置正确，并且在新生成的 .classpath 文件中找到了有关所需库的信息，则尝试运行play eclipsify如果它不起作用，只需重新启动 Eclipse。它对我有用。
