I'm just trying to use IDEA as the editor for some Scala code files already in existence here at my office. I have never written Scala before nor used IDEA for Scala, though plenty for Java.
To do this I used 'New Project', selected Scala with SBT and created the project within the existing code directory. Note that the file structure around the code is like
| - a/
| - A.scala
| - B.scala
| - b/
| - C.scala
| - c/
| - D.scala
First problem: in any file whenever the code references a class later in the file IDEA shows a code error "wrong forward reference". Ok actually it's often an object, not a class.
Second: In directory a, for example, where there are multiple scala files. The code often references classes in adjacent files in the directory. But every time IDEA shows a code error 'Cannot resolve symbol <class or method name>'.
Any advice? I think the IDE is using the Scala that I installed via Ports which is 2.10.
