Jenkins is an open source continuous integration tool written in Java. The project was forked from Hudson after a dispute with Oracle, which claims the right to trademark the Hudson name and has applied for such a trademark as of December 2010.
意 思就是，Jenkins的前身是Hudson（Sun开发），2010年从Hudson分支出来。由于Sun被Oracle收购，后者声称拥有 Hudson的商标所有权，前者被迫这样做的。分支出来的Jenkins将继续走open source道路，而Hudson可能会用于商业用途，二者都在继续开发中。
