RDF2Go/Building From Source
From semanticweb.org
RDF2Go (as well as RDFReactor) use Maven 2.0.9 for building from source.
Once Maven is installed (unzipped and on the path) go
org.semweb4j.rdf2go.api
and type
mvn install
It will run the JUnit tests, compile the code, package as a jar and put the result in the /target folder.
Now, do the same with
org.semweb4j.rdf2go.impl.base.test
and then
org.semweb4j.rdf2go.impl.sesame20 or sesame22
