This works at the commandline build.

In Eclipse (once):

1. change editor/Main.esv commenting out first line and uncommenting second line:

  provider : target/metaborg/Scalaproject-0.1.0-SNAPSHOT.jar // use this for commandline maven build
//  provider : ../Scalaproject/target/Scalaproject-0.1.0-SNAPSHOT.jar // use this in Eclipse (bypasses the copying step by using a relative path, but only works inside eclipse)

(though, do not commit this)

2. in the Scalaproject use the maven-build with package -DskipTests to generate a jar fast

In Eclipse (every build):

1. build scalaproject with maven (generates jar)
2. build spoofax project with spoofax (cmd+alt+b), reloads language with new jar.

Note: after a spoofax clean the scala-library will not be there anymore, so run the full maven build in the parent pom file.

Suggestion:

• bind Run Maven Build to shortkey, for example Ctrl+Alt+B (on mac)
