  #     -Dmaven.test.skip=false => Enable DSpace Unit Tests
  #     -DskipITs=false         => Enable DSpace Integration Tests
  #     -P !assembly            => Skip assembly of "dspace-installer" directory (as it can be memory intensive)
  #     -B                      => Maven batch/non-interactive mode (recommended for CI)
  #     -V                      => Display Maven version info before build

# After a successful build and test (see 'script'), send code coverage reports to coveralls.io
# These code coverage reports are generated by jacoco-maven-plugin (during test process above).
