【问题描述】：

为sbt 的命令行版本更改Ivy 主目录非常简单。您只需将选项-Dsbt.ivy.home=<new ivy home dir> 添加到$SBT_HOME/conf/sbtconf.txt。

我想对 IntelliJ IDEA 的 Scala 扩展做同样的事情（我的 C 驱动器上的磁盘空间不足）。因此，我通过以下方式修改了 SBT 设置：File -> Other Settings -> Default Settings -> Build, Execution, Deployment -> BuildTools -> SBT。在 VM 参数 下，我添加了条目 -Dsbt.ivy.home=<new ivy home dir>。这应该与命令行工具中的效果相同。

当我创建一个基于 sbt 的新 Scala 项目（并添加一个打印消息的 Scala 对象）时，一切似乎都运行良好。我可以构建和运行程序。但是在对源代码进行更改并制作项目（Build -> Make Project）两三次之后，我观察到以下错误：

重建项目（Build -> Rebuild Project）有效。但经过一些 make 迭代后，上述错误再次出现。 有什么我想念的想法吗？

【问题讨论】：

你怎么知道这是 ivy 的问题？？

当我删除选项 -Dsbt.ivy.home=<new ivy home dir> 时，我不再收到构建错误。我认为这是 IntellJ Scala 插件的问题，因为从命令行使用 sbt 效果很好。

【参考方案1】：

检查库，就我而言，我使用了 2 个不同版本的测试库
