Dependency download mechanism
Hi,
is the mechanism that downloads the dependencies specified in the
project object model a plugin or in some way adjustable?
I want to change the dependencies specified in the pom before their
download is tried. Is this possible?
Best regards,
Harald

ok, that looks promising. I will try that.
Thanks a lot,

yup. You would have to declare the 0.8 dependency as 0.8-SNAPSHOT. Then
it would check the timestamp of the remote file and download it if it's new.
That's the only workaround I know about. Non snapshots are never
downloaded when in the local repository.

I tried a similar approach first: Version 0.8 was a symbolic link that was
updated every time a new minor version was released. The problem with this
approach is that if somebody already downloaded a 0.8 version he will not
get future 0.8 versions as Maven won't download newer versions.

Why don't you simlpy replace the 0.8 version within the repo then and
archive the minors (0.8.x, 0.8.y) elsewhere?

the idea is to allow users to specify "partial" version numbers for
dependencies (at least for internal dependencies). So "0.8" means download
the artifact in version "0.8.x" with the highest available x. The
functionality should be similar to snapshots. If a new version of the
dependency appears, it should be used in future builds.

AFAIK is this part of the maven core.

Why do you want to do that? What do you want to achieve?
