Eclipse没有更新我的Play框架应用程序的引用库

Question

由于我渴望在我的Play 2项目中使用弹性搜索，我已经通读了一遍http://www.elasticsearch.org/guide/reference/java-api/和添加了依赖项：

Build.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:

但在eclipse中，我不能使用弹性搜索，因为它找不到库。我不是甚至可以导入。

我在这里错过了什么？

Answer 1

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

它将为Eclipse生成一个新的.classpath文件，其中包含您的新依赖项。

Answer 2

如果Build.scala设置正确，并且在新生成的.classpath文件中找到了关于所需库的信息，则尝试运行播放Eclipse，如果不起作用，只需重新启动Eclipse。它对我有效。
