Question

我想知道是否有人在尝试运行SBT时遇到java.io.FileNotFoundException的任何经验。

当我尝试让SBT运行时，我得到以下错误。这在我尝试加载项目定义时输入sbt后立即发生。

我检查了它说它无法访问的文件，它们肯定在那里，我完全不知道它为什么会这样做。

堆栈跟踪如下：

Answer 1

(Permission denied)错误表明您可能正在运行sbt命令，该用户对您输入sbt的项目没有权限。

使用chown -R youruser:youruser /path/to/project更改文件夹权限，它应该修复它。

Answer 2

问题可能是您以root身份运行sbt并且目标文件夹中的几个目录变为root（因此权限被拒绝问题）。您只需运行sudo rm -rf target/，然后sbt clean compile即可重新获得您帐户下的已编译文件。为我工作。

Answer 3

答案都没有帮助，但是@Priyatham提出了一个好主意：我还删除了project/project和project/target文件夹-并且可以正常工作。

SBT在项目文件夹上抛出java.io.FileNotFoundException :(权限被拒绝）
