Proxying Maven central [message #1537372]

Hello,

First of all, to avoid misunderstandings : I didn't solve my proxy-problem yet (as mentionned in my previous post). I'm just trying at home and there no proxy is used.

When trying to map Maven Central, I encounter a quite curious phenomenon: b3 only recognizes a very small subset of available projects (see attached screenshot).

When building the aggregate site and trying to install software from it, the available software gets even more reduced : only the groups acegisecurity, activemq and cocoon are available. I don't know why (and anyway I don't need those).

Has anyone an idea 1) what is happening here and 2) what I'm doing wrong ?

Thanks in advance,

Thomas

The b3 aggregator aggregates only p2 repositories, not maven
repositories. Is that the answer to your question?<br>

It answers my question indeed : the documentation of b3 aggregator left me puzzled about this ("p2 and maven2 support -- the aggregator can aggregate from and to both p2 and maven2 repositories").

Thanks for the clarification,

Thomas

That's correct in practice. In theory, there is actually a 'maven2' nature that can be set for a mapped repository. When
set, b3 will make an attempt to pull from a repository with maven2 layout. If the "Nexus Indexer for Maven" feature is
installed, and if the repository in question is indexed, it might succeed in doing so but without it, you're probably
out of luck.

In any case, the 'pull from maven' functionality needs more work and I wouldn't recommend building a solution on it as
it stands today (unless you're also willing to contribute to b3 to improve that situation of course).
