I had really bad experiences with this repositories. They are often outdated with current releases. ie: few days ago, in the repositories i was not able to find log4j version 1.2.9. I am not sure if now the 1.2.9 is there. I bet is still missing.... Until some charitative soul will take care of that. Is supposed that Apache jars are automatically in the repos, but this is not true currently. The situation is worse with non-apache libraries.
Well, I also needed to get the eclipse compiler updated (javaflow uses maven). And I've put the library into jira. To be honest it took a few days. ...I got some things wrong and stuff. But it wasn't *that* bad. I really like the repository idea.
BTW: there is an apache repository where you can copy apache jars into. It will be synched automagically!
Another problem is with what version are compiled the jars. We need to make sure that for 2.1.x branch they need to run in java 1.3 and 1.4 for 2.2.0 branch. And this is not the case with some jars you find in the repositories.
Well, this is of course a good point :-/
