fix(build): use maven with the wrapper script to build

[valters]

I could not track down a reliable source for prefuse and sdoc. For now to build locally one needs to put in into local Maven repo like this:

./mvnw install:install-file \
  -Dfile=lib/prefuse.jar \
  -DgroupId=prefuse \
  -DartifactId=prefuse \
  -Dversion=0 \
  -Dpackaging=jar \
  -DgeneratePom=true

./mvnw install:install-file \
  -Dfile=lib/sdoc-0.5.0-beta.jar \
  -DgroupId=com.github.vertical-blank \
  -DartifactId=sdoc \
  -Dversion=0.5.0-beta \
  -Dpackaging=jar \
  -DgeneratePom=true
