问题
The path from SBT to Scala-IDE is well described in many places:
- Start with an SBT project
- Add the SBT plugin definition: addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0-RC1")
- Run the 'eclipse' command from within SBT
- Open Eclipse with an installed Scala-IDE add-on
- Import the project
What is the reverse for this? If I start a new project in Scala-IDE, can I just add a build.sbt file and somehow tell Eclipse to use this when running the application?
Apologies if this seems obvious to some, but I've recently moved from ItelliJ Idea to Scala-IDE and I'm not certain about setting up Scala-IDE to use SBT and my sbt config files.
回答1:
No, you cannot do this. The way to do it is as you described. Then, whenever you make changes to build.sbt (e.g., new jar dependency), rerun the eclipse command from sbt and refresh the project in Eclipse so that the newly generated files are reloaded.

As a seasoned Eclipse user, I wondered the same thing. Amazed that no one seemed to be going that direction, I decided to roll my own project.

Install plugin, create or modify build.sbt and dependencies are fetched, project files updated.
It works for me, I use it every day. But it's not perfect or finished, and I'm not putting in a lot of effort in it at the moment. But do feel free to contribute!
