Jeremy Boynes of GlueCode / Apache Geronimo says:
To all those who have been making “improvements” to the build over the last month, can we please please get back to a situation where it works reliably, every time on Windows, Linux and OSX.
No magic, no mystical plugin downloads, no arcane sequences to rebuild, no patches to apply, simply:
* Clear instructions on building on a clean machine
* Clear instructions on rebuilding a working copy
* The ability to build online without taking hours
AND THEN STOP MESSING WITH IT!
I am on the Geronimo lists, and have seen that 80% of the emails are about the damn build :)
If you were thinking of using Maven, being part of this list would REALLY freak you out about it! ;)
