I think ivy-local should require maven-local otherwise the xmvn resolver in /etc/ivy/ivysettings.xml is non-functional.

Without maven-local:

[ivy:resolve]
[ivy:resolve] :: problems summary ::
[ivy:resolve] :::: WARNINGS
[ivy:resolve]   [XMvn] No XMvn configuration files were found. Using default embedded configuration.
[ivy:resolve]           module not found: xmlenc#xmlenc;0.52

[ivy:resolve]           module not found: commons-codec#commons-codec;1.4

With maven-local:

ivy-resolve:
