July 15, 2011 By Brian Fox

Sonatype is going through the archives and digging up articles that we think would be useful to developers using our tools. If you use Maven, keep reading the post below from Sonatype Vice President of Engineering Brian Fox on Maven best practices and how-tos.

We have a handful of Maven best practice and how-tos documented in the blogs. Over time they get buried by newer posts, but the content is still just as relevant. Learn more about Maven by checking out the following blogs:
