We have been faced with the choice of going with Hudson or Jenkins as our CI enviroment for our ADF build.
Oracle backed Sonatype supported. More structured.
More OSS style, larger comunity majority of the orginal developer community.
Really very similar.
Guess the safest thing to do is go with Hudson and upgrade to Jenkins if need be. So we will be going with Hudson, head decision not heart decision. This is also consistent with the ADF community.
