因为我很想在我的 Play 2 项目中使用 Elastic Search，所以我通读了 http://www.elasticsearch.org/guide/reference/java-api/和 添加依赖:
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 Play 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。我不是 甚至可以导入它。
我在这里错过了什么？
最佳答案
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。
它将为包含新依赖项的 Eclipse 生成一个新的 .classpath 文件。
关于Eclipse 不更新我的 Play 框架应用程序的引用库，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12727510/
