vertx stack cache aether infos

[vietj]

• snapshot : cached for one day
• info should be cached in $VERTX_HOME/something_that_makes_sense

I'm not sure we should cache snapshots. It's probably better to let Aether deal with snapshot caching.

[vietj]

if we don't do it for snapshot, we cannot really test this feature with SNAPSHOT when trying the stack ourselves, right ?

[cescoffier]

I've test using vertx-core 3.1 explicitly to test released artifacts. So test would use this too.
In addition I can build a stack using whatever release artifact from Maven central.

I'm trying the tool and usability and how people are going to use it, howe it goes etc..., we need to have a --cache-snapshot configuration or something like that ?

or as an env variable
