> The problem is caused by a slightly obscure sequence, in this example, I use two projects, Server & Common. Server depends on Common:
> Alice updates Server to depend on Common-1.2-SNAPSHOT instead of 1.1-SNAPSHOT and commits that change.
> Bob syncs that change and attempts a build of Server, maven checks for Common-1.2-SNAPSHOT in the local repo, finds it missing and checks the global repo, where it is also missing. Maven records this information in a cache and fails the build.
> Alice deploys Common-1.2-SNAPSHOT to the global repo.
> Bob attempts to build Server again, maven checks it's cached information and finds that Common-1.2-SNAPSHOT wasn't in the global repo last time, so fails the build.
> Maven should not fail the build due to missing dependencies simply because the cache says the dependency was missing last time. It should check the configured repos before failing.
