even though I haven't been active in jmeter in a while, I am still a jmeter committer.
quite honestly, I've seen maven work first hand. 1. the claim it reduces maintenance has not truth. My first hand experience is that it creates a much bigger burden. 2. changing the directory structure of jmeter to fit maven is wrong for several reasons. due to maven's "suggested structure" it's common to run into path length issues on windows platforms. When i was responsible for maintaining maven builds, we often had to rename unit tests because it exceeded 255 characters. Forcing everyone to use and build on linux or unix is not acceptable in my book. 3. not everyone wants or cares to install maven. 4. maven 1 and 2 are both slow 5. maven repositories are notoriously unreliable. when maven repositories go down, maven builds fail until that repository comes back. A few years back codehaus went down due to hardware failure. people that relied on codehaus + maven ended up having build issues 6. maven 1 & 2 repositories are poorly designed and do not support versioning properly from first hand experience. Back when I maintained maven builds, we ended up creating multiple maven repositories internally so that we could support multiple releases. bottom line is, maven is poorly designed and not worth the hassle. Plenty of people find it works fine for them, and there's lots of people who love maven. I am not one of those people.
