Benjamin, thanks for correction.
My understanding is that it may take time for sync to actually occur, and if one doesn't want to wait for that, one should add codehaus repo as (plugin) repo to access not-yet-synced-to-central artifacts. But it's not the case here, seems sync happened day before announcement, 5h after release on codehaus repo (if clocks are in sync).
Also, only releases are synced to central, so if one want's to access snapshots too, one should add the codehaus repo definition. Since 2.0 is not a snapshot, this wasn't the case here.
So it leads me to that either Takanori didn't specify plugin dependency well, or has problems accessing central, ...

Stevo.
