I am actually going to say the contrary. You should, at I'd even say, you *must* wipe out Maven repositories on a regular basis. If you don't, and you have static (persistent) agents, very bad things will happen at some point. So, yeah, redownloading it is going to add some time to build, but this is a matter of speed vs. reproducibility, so better target reproduciblity/non flakiness then see how to optimize, not the contrary. And obviously, *NEVER, EVER share that .m2/repository between running builds*. > > > > Thanks > > Rice. > > > > > -- > Guang <http://javadevnotes.com/java-string-to-integer-examples/> >
