Hi again, Chris. Well, for us, all the M1 artifacts go in $HOME/.maven/repository and M2 artifacts go in $HOME/.m2/repository. If the M1 artifacts have discrete metadata (that is to say, some difference of groupId, artifactId, and/or version) of your M2 artifacts, then every time you build with M2, the M1 repository will be checked for updates of those artifacts according to your updatePolicy. (Sounds like you'd want "always".) (If you use the same metadata in both M1 and M2, of course, Maven2 will overwrite any Maven1 file with the same information.) M2 will take each of those M1 artifacts and store a local copy in *its* repository. (Just as if you downloaded it from central.) Then let the M2 repo be the master repository. Since it's not simple to have M1 see your M2 repo, letting your M2 builds set the course for future development is key. If you choose to discontinue M1 builds, all you will have to do is remove the repository from your settings.xml. If you need M2 artifacts in your M1 build, I would discourage this practice -- it's very, very far from convention and will likely cause pain. To convert fully to M2 will likely cause less pain in the long run and you will see other benefits.

I do use the <layout>legacy</layout> element to access my M1 repo from maven2, but what do you mean by "specify a different folder for your Maven2 repository?" The only thing I can think of is to copy the contents of my $HOME/.m2 directory to my maven2 repo. Basically I need to keep both repo's in synch. I like the idea of a proxy that gives me different views of the same data, I haven't found one that does it (or has it documented.)

Maven2 can navigate Maven1 repositories well. I would define your M1 repo as a repository that your M2 build can use. Just specify <layout>legacy</layout> in your <repository> definition. If you specify a different folder for your Maven2 repository, the first time you run a Maven2 build, it will download all the relevant dependencies from the M1 repo and install them to the correct location in your M2 repo.

I would like to convert them to maven2, but I'd like my existing maven1 builds to keep working. How do I do this?
