Hi,

I'm packaging some Java packages for guix https://www.gnu.org/software/guix/, a functional package manager (much like nix).

I would appreciate some assistance for understanding how to leverage Xmvn in this case.

Guix installs each package into a prefix of it's own, e.g.:

/gnu/store/...-plexus-io/share/java/plexus/io.jar
/gnu/store/...-dom4j-1.6.1/share/java/dom4j/dom4j.jar

Thus Xmvn shall pick up artifacts and meta-data from all prefixes belonging to the current profile/environment. Each prefix could contain a .../xmvn/configuration.xml and $XDG_DATA_DIRS could be used to get a list of these.

I tried this and it worked different then expected.

I tried to use the "prefixes" (according the the Xmvn configuration reference [1]) as shown below. But the Xmvn does not even try to access these prefixes. Can somebody explain why, please?

<configuration>
  <resolverSettings>
    <prefixes>
      <prefix>/gnu/store/...-plexus-io</prefix>
    </prefixes>
  </resolverSettings>
</configuration>

I learned that I need to define <metadataRepositories>, which worked. But I'm wondering what are the <prefixes> then used for and how to test whether my set-up is correct.

Thanks in advance for any answer.
