New issue 453 by zwel...@gmail.com: onebusaway-gtfs-module fails to compile
http://code.google.com/p/onebusaway/issues/detail?id=453

I tried to compile a copy of onebusaway-gtfs-modules, but failed.

I used:
svn co http://onebusaway.googlecode.com/svn/onebusaway-gtfs-modules/trunk
onebusaway-gtfs-modules
mvn package

Which caused errors because of a maven 3 dependency:

After which I was greeted by yet another friendly error:

Which I'm hoping that you will be able to fix...

I'm using:
Apache Maven 2.2.1 (rdebian-4)
Java version: 1.6.0_18
Java home: /usr/lib/jvm/java-6-openjdk/jre
Default locale: en_US, platform encoding: UTF-8

Sorry for not responding to this sooner. I've upgraded to requiring Maven
3 to build OneBusAway. I will take a look about specifying the site module
version to see about Maven 2 backwards compatibility. Any chance you could
use Maven 3?

I had feeling maven 3 was being used...

Debian doesn't have packages for maven 3 (yet). But, maven.apache.org has
executables for download, so there isn't anything blocking me from using
maven 3.

After downloading the executable, things seems to run fine. But I still get
the errors mentioned previously compiling the source. It's probably another
OpenJDK generics "problem" like #254.

I think it's easier to keep this compatible with Maven 3. I'm going to
close this bug for now.
