I recently treid to compile the DBPedia Extraction Framework. What was not immediately clear to me is whether I have to have Scala installed. It turns out that having Scala installed natively is not necessary, seeing as the scala-maven-plugin is sufficient.

The steps to compile DBPedia Extraction Framework from the command line are:

1. Ensure you have the JDK 1.8.x installed.
2. Ensure Maven 3.x is installed.
3. mvn package

Steps to compile DBPedia Extraction Framework from the Scala IDE (which can be downloaded from Scala-ide.org) are:

1. Ensure you have the JDK 1.8.x installed.
2. Ensure you have the Scala IDE installed.
3. mvn eclipse:eclipse
4. mvn package
5. Import existing Maven project into Scala IDE.
6. Run mvn clean install from within the IDE.
