How to start?

  1. start the sbt console with ./activator or activator.bat

  2. In the sbt console, compile the project with compile. The project should compile without any errors.

  3. In the sbt console, let the tests run with test. No surprise, the tests are not successful.

More commands:

  • run runs a program (main class)
  • test launches the tests
  • testOnly *.MyTest launches only the tests with the full name matching *.MyTest
  • testQuick launches only the tests that failed and the tests impacted by the changes
  • ~<command> trigger the each time the code is changed. For example, ~testQuick is a good way to practice TDD.

  2. create a new project from existing sources by selecting the file build.sbt.

Scala IDE (based on Eclipse)

In Scala IDE:

  1. Start the sbt console

  2. Enter eclipse with-source=true

  3. Open the generated project with Scala IDE.
