Re: [tycho-user] [WARNING] The following locally built units have been used to resolve project dependencies

Reactor projects are expected to "mask" locally installed artifacts and
artifacts available from remote repositories. I believe the warning
is only printed for project dependencies installed locally by other builds.

Generally, though, when you run "mvn install", you explicitly tell Maven
to share build results in the local repository. If you don't want to
share the build results, then you run "mvn package". If you want to
share results among some builds but not others, you use separate local
repositories. This is how Maven has worked since at least 2.0 and there
is no reason Tycho should deviate from this. There are some talks among
Maven developers to separate "remote artifact cache" from "locally
installed artifacts" and we may want to implement something similar in
Tycho, but I am not sure if and when this is going to happen.

Would it be possible for Tycho - when the dependency is in the current
reactor build and in your local Maven repository - to prefer the
components in the current build to alleviate this problem?

Or is the concern that this will preclude Tycho's use of cached
artifacts from previous builds?

Thanks,
Matt

    Yes, this would prevent cross-talk between the different builds, and
    is probably what you want.
