Subject: [PATCH] [AURON #2459] Resolve build info paths relative to
 auron-build.sh

auron-build.sh resolved both the build info file and the Maven used to
look up project.version relative to the caller's working directory. Run
from anywhere other than the project root it wrote
auron-build-info.properties outside the project, so the build never
picked it up, and project.version was dropped from the file because the
lookup failed into /dev/null and empty values are skipped.

Resolve SCRIPT_DIR from BASH_SOURCE and use it for the build info file,
reuse the already resolved MVN_CMD instead of a hardcoded ./build/mvn,
and pass -f so Maven reads the project pom rather than falling back to
its standalone pom, which reports version 1. Fail with the captured
Maven output when the version cannot be resolved, rather than shipping a
jar with no version in it.
