Question

How to initialize a new Scala project in sbt, Eclipse and github, so that it all plays together...

Answer 1

Previous answer/s is/are of high importance as well as the question since these tools are not self explanatory. Based on personal experience with this challenge which seemed impossible but when one acknowledges few key insurance policy reference points things will become reality:

1. Implementation of development environment may require radical re-installation as new tool is adopted (if you adopt GIT after you already had SBT in place you may need to empty SBT's working directory as GIT require the cloning process to have empty house on local working directory)
2. Keep really well updated backups especially when considering re-setting any of this "domino" environment layers as some of the GUI or command initiated cleansing operations truly take care of that sometimes with surprising effectiveness and without any regard to other tools / layers requirements
3. Keep really good documentation (including previous pragmatic answer) on key stages to make things a reality (again)
