I've been trying to build the hornetq project and having issues when it gets to building the docs. any hints on the maven error below? it says it timed out but the jar is accessible at the specified url and even though it says unresolvable build extension, the jdocbook extension is defined.
[ERROR] The build could not read 2 projects -> [Help 1]
