如何在IntelliJ IDEA中更改Ivy home

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

我想对IntelliJ IDEA的Scala扩展做同样的事情（我的C盘上的磁盘空间不足）。因此，我按以下方式修改了SBT设置：文件 - ＆gt;其他设置 - ＆gt;默认设置 - ＆gt;构建，执行，部署 - ＆gt; BuildTools - ＆gt; 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具有相同的效果。

当我创建一个新的基于 sbt 的Scala项目（并添加一个打印出消息的Scala对象）时，一切似乎都很好用。我可以构建并运行该程序。但是在对源代码进行更改并使项目（ Build - ＆gt; Make Project ）两次或三次之后，我发现以下错误：

重建项目（ Build - ＆gt; Rebuild Project ）有效。但是在一些 make 迭代之后，上面的错误再次出现。 我想念的任何想法？

答案 0 :(得分：0)

检查库，在我的情况下，我使用的是2个不同版本的测试库
