Data management cli doesn't read settings.xml

DMC doesn't read settings.xml file (proxy + Continuum beta-4 stage repository)

settings.xml file is located under $

/.m2/

Here is what I get when I try to execute DMC and then dependency:resolve with DMC pom file.

DMC alone :

[robot@CC ~]$ java -jar data-management-cli-1.1-beta-4-app.jar ...
0 [main] INFO org.apache.maven.continuum.management.DataManagementCli

• Processing Continuum database...
  Exception in thread "main"
  org.apache.maven.artifact.resolver.MultipleArtifactsNotFoundException:
  Missing:
  ----------
  1) org.apache.maven.continuum:data-management-jdo:jar:1.1-beta-4

Try downloading the file manually from the project website.

Then, install it using the command:
mvn install:install-file -DgroupId=org.apache.maven.continuum
-DartifactId=data-management-jdo \
-Dversion=1.1-beta-4 -Dpackaging=jar -Dfile=/path/to/file

Path to dependency:
1) dummy:dummy:pom:1.0
2) org.apache.maven.continuum:data-management-jdo:jar:1.1-beta-4

<= same session, same maven 2, same settings.xml =>

Then, with DMC pom file :

[robot@CC ~]$ mvn dependency:resolve

Maven itself finds settings.xml and its configuration, but DMC fails.
