升级到sbt 0.13.9；现在我无法启动sbt

Question

我将sbt从0.13.8升级到0.13.9。我们有Nexus代理了许多存储库。现在，当我发出sbt命令时，我得到了未解决的依赖项。

scala-library
scala-compilre
scala-reflect 

这一切都是由于sha1与计算结果不同。有没有绕过sha1验证的方法？仅供参考。在checksums in update := Nil中设置build.sbt并不能解决这个问题。我甚至试着把<property name="ivy.checksums" value=""/>放进~/.ivy/ivysettings.xml，但还是失败了。

以下是控制台输出：

D:\Temp\test>sbt -v update
Getting org.scala-sbt sbt 0.13.9 ...

Answer 1

结果是我们的Nexus代理存储库出现了排序问题。当oss.sonatype.org被放置在maven Central之前时，它引起了一个问题。移除oss.sonatype.org maven存储库解决了这个问题。
