Hi all,

I'm wondering if the nexus settings[1] in the nexus book is not quite correct. (be carefull if you google nexus book!)

Let me explain, by default this enables snapshot plugins, so you can get arbitrary quality plugin if you run a plug-in from the command line where there is no pom to lock down the plugin (e.g. mvn archetype:generate), or you are using an obscure plugin that you wouldn't think to lock down in your corporate pom.

Our corporate pom defeines most of the plugin versions however you can't cover all cases - and even if you could you have the issue where you don't have a pom.

I first tried setting snapshots enabled to false on the plugin repo however as nexus returns the merged metadata with the latest version being the snapshot maven then tries to download x.x.x-SNAPSHOT and fails (as there is no repostiroy for plugins that can hold snapshots!)

I found a solution and I'm attaching it. I was wondering though if

1) anyone can see any potential pitfalls with this (apart from not getting snapshot plugins which IMHO is a good thing and what maven does out of the box)

2) if this is ok should it replace the example in the nexus book so it more closely mimics the standard out of the box maven behaviour?

Regards,

/James
