The Jenkins community is promoting a number of bellwethers that would indicate that Hudson is losing the game when it comes to both mindshare and adoption. 85% of upgrades go to Jenkins. Jenkins GitHub repositories outnumber Hudson by a ratio of sixty to one. Jenkins 'ticket activity' is significantly higher than that of Hudson. "It all adds up to the fact that Jenkins is where the community is - they are committed and enthusiastic," says Steve Harris, CloudBees' SVP of Products, in his October 18th blog posting on the topic. "The numbers really speak for themselves."
But it's far too early to declare a winner in this debate. The Jenkins/Hudson split is only about six months old, and with Oracle and Eclipse behind Hudson, the Hudson horse is hardly even out of the gate. More time is definitely needed before any player is counted out of the continuous integration (CI) fight.
