为Scala / SBT设置IntelliJ IDEA Ultimate

Question

I' ve been struggling with setting up IntelliJ IDEA Ultimate for use with Scala/SBT for the past couple of hours and currently i am facing an error that i dont even know how to look up properly. Googleing the error code didnt help unfortunately :(.

So, everytime i set up a new project or import an existing one, following the instructions found here:

https://scala-lang.org/documentation/getting-started-intellij-track/building-a-scala-project-with-intellij-and-sbt.html

and

https://www.jetbrains.com/help/idea/creating-and-running-your-scala-application.html

i am getting the following error msg as soon as the project has finished loading:

Error:Error while importing SBT project:

I have properly installed SBT 1.0.3 and the scala plugin 2.1.14.

Do you have any idea what i can do about this? I need to hand in the project in 2 weeks and our teacher specifically requires us to use IntelliJ IDEA.

Answer 1

Lorenz I had exactly the same problem. When reading the whole error message i found https://dl.bintray.com/sbt/sbt-plugin-releases/org.apache.logging.log4j where sbt seems to search for an update, but it is not available.

My solution was, to use older SBT and Scala plugins: I'm now using SBT 0.13.13 and Scala 2.12.0 and everything is working fine so far. (JDK version should be 1.8)

I hope it will work for you too.
