scala – 即使文件清楚存在,SBT也无法在存储库中找到

导读：存储库 http://teleal.org/m2返回的内容有什么问题吗？这是我的build.sbt -file： organization := "org.messy"name := "mess"version := "1-SNAPSHOT"scalaVersion := "2.9.1"libraryDependencies ++= Seq( "org.teleal.cling" % "cling-core" % "1.0.5","o

存储库 http://teleal.org/m2返回的内容有什么问题吗？这是我的build.sbt -file：

organization := "org.messy"

name := "mess"

version := "1-SNAPSHOT"

scalaVersion := "2.9.1"

libraryDependencies ++= Seq(
  "org.teleal.cling" % "cling-core" % "1.0.5","org.teleal.cling" % "cling-support" % "1.0.5"
)

resolvers ++= Seq(
  "cling" at "http://teleal.org/m2"
)

……这就是我得到的错误.这里的teleal.org-URL可以直接在浏览器中打开,现在出现问题：

更新

差点忘了;我在Mac OS X上使用sbt-0.11.0.

摘要

存储库teleal.org通过返回响应状态204来回复来自sbt的头部请求.响应状态应该与获取请求200相同.因此,sbt得出结论,这里没有什么可看的.

如果teleal.org选择不支持像maven central那样的头部请求,那么这样做会很好;它认为:-)

边注; sbt使用这个有趣的接受标题：’接受：text / html,image / gif,image / jpeg,*; q = .2,/; Q = 0.2′

解决方法

要从更新任务中查看调试级别日志记录：

> set logLevel in update := Level.Debug
> update

或者,在运行更新后,您可以显示调试日志记录,该日志记录已保留到磁盘但未显示：

> last update

你会看到的：

[debug]      trying http://teleal.org/m2/org/teleal/cling/cling-core/1.0.5/cling-core-1.0.5.pom
[debug]         tried http://teleal.org/m2/org/teleal/cling/cling-core/1.0.5/cling-core-1.0.5.pom

该URL的HTTP响应包括HTTP重定向：

常春藤可以遵循重定向,但让我们直接使用新的存储库来消除任何疑问.仍然不起作用,我们仍然得到204错误.

该服务器返回HTTP 204(无内容),但Ivy,版本2.2.0,is unable to handle.

解决方法是代理存储库. free version of Sonatype Nexus可以做到这一点,并且很容易设置.
