sbt - 为什么 sbt updateClassifier 无法下载 org.scala-sbt#precompiled？

Question

在 unix shell 中试试这个:

git clone git@github.com:jsuereth/sbt-in-action-examples.git
cd sbt-in-action-examples/chapter11/scalastyle-plugin/
sbt updateClassifiers

使用 sbt 0.13.7，我得到了这个:

[warn]  [FAILED     ] org.scala-sbt#precompiled-2_8_2;0.13.7!precompiled-2_8_2.jar:  (0ms)

这些警告正常吗？

我注意到 SBT 试图寻找这些工件的 URL 与发布的工件的 URL 不匹配。

也就是说，sbt 正在寻找这些工件:

https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_8_2/0.13.7/jars/precompiled-2_8_2.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_2/0.13.7/jars/precompiled-2_9_2.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_3/0.13.7/jars/precompiled-2_9_3.jar

但实际上，可用的工件是这些:

https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_8_2/0.13.7/jars/compiler-interface-bin.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_2/0.13.7/jars/compiler-interface-bin.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_3/0.13.7/jars/compiler-interface-bin.jar

似乎上面的“compiler-interface-bin.jar”工件对应于此处的“源”工件:

https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_8_2/0.13.7/srcs/precompiled-2_8_2-sources.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_2/0.13.7/srcs/precompiled-2_9_2-sources.jar
https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/precompiled-2_9_3/0.13.7/srcs/precompiled-2_9_3-sources.jar

我猜测这些是由 https://repo.typesafe.com/ 的不稳定性引起的。 (重定向代理)或 Bintray。我不认为他们是正常的。

对于它的值(value)，我能够运行 updateClassifiers美好的。
