构建SBT项目时，原点位置必须是绝对错误的，IntelliJ

Question

我正在尝试使用IntelliJ构建简单的hello world SBT-Scala项目。

在安装scala/ SBT插件之后，当我第一次尝试创建项目时，我得到了以下错误：

Error:Error while importing SBT project:<br/>...<br/><pre>[info] Resolving org.scala-lang#scala-reflect;2.11.8 ...

有没有办法解决原点位置一定是绝对误差的问题？

请注意，我能够找到文件scala-reflect-2.11.8.pom，这与错误说明: file:/root/.m2/repository/org/scala-lang/scala-reflect/2.11.8/scala-reflect-2.11.8.pom不同

我的build.sbt文件：

name := "SuperSimpleRootScalaSBT4"

version := "1.0"

scalaVersion := "2.11.8"

我的sbt版本是0.13.15。

Answer 1

删除我的~/.ivy2对我有帮助

Answer 2

删除~/.ivy2是可行的，但不是最好的选择，然后你必须重新下载所有缓存。而是从缓存中删除您面临问题的特定目录。

在您的示例中，它应该是~/.ivy2/cache/scala.lang并重新构建

Answer 3

我也面临着同样的问题：

不用删除.ivy文件夹，只需备份它(将文件夹.ivy2重命名为.ivy2.backup in instance)，然后再次测试，例如

$ sbt new scala/hello-world.g8

现在应该可以正确创建和设置项目了
