Why might Nexus 2.0 not cache remote artifacts?
Not sure if you can help. And if you can recommend a better place, please inform me.
I downloaded and installed Nexus 2.0 under 64-bit ubuntu. Nexus starts up and is available on default port 8081. I enabled "Download Remote Indexes" for repositories. The "Browse Index" tab for each repository shows the index tree.
However, when I try to hit the repo from a maven goal (e.g. mvn clean) it is unable to find any artifacts in the Nexus 2.0 cache.
$ mvn clean
