如何在IntelliJ IDEA中更改Ivy home

更改Ivy主目录的命令行版本为sbt很简单。您只需将选项-Dsbt.ivy.home=<new ivy home dir>添加到$SBT_HOME/conf/sbtconf.txt即可。如何在IntelliJ IDEA中更改Ivy home

我想用IntelliJ IDEA的Scala扩展（我的C盘上的磁盘空间不足）执行相同的操作。因此，我通过以下方式修改了SBT设置：文件 - >其他设置 - >默认设置 - >构建，执行，部署 - > BuildTools - > SBT。在虚拟机参数我添加了条目-Dsbt.ivy.home=<new ivy home dir>。这应该与命令行工具具有相同的效果。当我创建一个新的基于Scala项目（并添加打印出一条消息的Scala对象）时，一切似乎很好地工作。我可以构建并运行该程序。但对源代码进行修改，使该项目后（建设 - >使项目）两三次，我遵守以下错误：

重建项目（建设 - >重建项目 ）的作品。但在一些使迭代后，上面的错误再次出现。任何想法我想念？

你是如何知道这是常春藤的问题？ –

当我删除选项'-Dsbt.ivy.home = '我不再有构建错误。我认为这是IntellJ Scala插件的问题，因为从命令行使用* sbt *可以正常工作。 –

检查库，在我的情况下，我正在使用2个不同版本的测试库
