我很确定我设置了emacs，insime，sbt和scala可以正确工作。我可以编辑文件并在保存并成功尝试使用Ensime的自动归于工具时查看类型错误。
问题是当我尝试构建项目时。无论是否没有任何错误，按C-c C-b b都会给我这个输出：
Latest Compilation Results (q to quit, TAB to jump to next error)
----------------------------------------
0 errors, 0 warnings.
然后我注意到卧铺没有加载任何导致我问这个问题的东西，但是我发现，如果我通过从命令行调用sbt compile来构建我的项目，我可以构建我的项目，并且使用repp。
我还看到，在我用sbt compile成功构建项目后，然后尝试从事该项目并调用"增量构建"（C-c C-b r），我会得到：
Asynchronous RPC Aborted: Error occurred in incremental builder. Check the server log.
在迷你缓冲器中。这就是*inferior-ensime-server*缓冲区中出现的内容：

如果我尝试使用C-c C-b b进行完整构建，则我会得到原始的缓冲区没有显示错误或警告（无论是否曾经是这种情况），并看到原始类目录将被删除。p>为什么会发生这种情况？如何获得C-c C-b b和C-c C-b r正确构建项目？
编辑：
似乎正在安装ensime的目录内生成类文件，这对我来说似乎很奇怪...
编辑2 ：
我在启动时在*Messages*中获得以下内容。我不知道这是否相关：
Eager macro-expansion failure: (error "(ensime-builder-changed-files (ensime-connection)) is not a valid place expression") [3 times]
这些问题是由于insime中的错误造成的；两者都应固定在当前的git树中：
