为什么sbt updateClassifier不能下载org.scala-sbt#预编译？

Question

在中尝试这样做：

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，我了解到：

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：

2.jar 2.jar 3.jar

但事实上，可用的文物是：

2/0.13.7/jars/compiler-interface-bin.jar 2/0.13.7/jars/compiler-interface-bin.jar 3/0.13.7/jars/compiler-interface-bin.jar

上面的“编译器-接口-bin.jar”工件似乎与这里的“源”工件相对应：

2-sources.jar 2-sources.jar 3-sources.jar

Answer 1

我猜想这是由https://repo.typesafe.com/ (重定向代理)或Bintray的不稳定性造成的。我不认为他们是正常的。

不管它的价值是什么，我能够运行updateClassifiers罚款。
