I am trying to import this simple project to IntelliJ: https://github.com/Codemunity/akkahttp-quickstart I cloned the repo, and used "File -> Open" to open the project in IntelliJ.
Unfortunately, I get Extracting structure failed and IntelliJ seems not to recognise that my build.sbt is a sbt file (it highlights all sbt statements in red).
In fact I cannot import any sbt project that I download from GitHub. But on the other hand I can create a simple "hello world" project myself and I do not have any such problems with this.
What to do to import this project?
