I see your point, although I don't know how often you need to add this option to the commandline to be able to build your project. I would expect almost every time once you're hitting this issue.
Still I have my doubts if it should be a new option.

From the CLIManager:
options.addOption( OptionBuilder.withLongOpt( "simple-local-repository-manager" ).withDescription( "Use a simple Local Repository Manager, ie no use of _maven.repositories. Can be activated using -Dmaven.simpleLocalRepoMan=true" ).create(
            SIMPLE_LOCAL_REPOSITORY_MANAGER ) );

'mvn <phase> -Dmaven.simpleLocalRepoMan' would be good enough for me if it only happens now and then.
(but this should be changed to -Dmaven.legacyLocalRepo ...)

I like the "legacy" advertising (both for cli and system property), which
helps people understand this option should be avoided: with the later warning
during execution, they should report until we understand and document
sufficiently conditions where it is needed and options to fix the build in a more
reliable way

I'm less inclined to removing mvn argument: only supporting MVN_OPTS will
force users to set the system property, then have the option enabled for every
builds
I think this would have the counter effect of using the option more than
necessary

Hi,

I have my doubts if this should be exposed as a mvn argument. This would
also mean that we cannot remove it in the future. It would also suggest
that it is a valid solution, but in fact it makes your build more
unreliable.
Users hitting this issue have often enough Maven knowledge to discover
this option, so I don't see the need for this mvn commandline argument.
Instead I would only use the MAVEN_OPTS option, and rename it to
LegacyLocalRepository instead of SimpleLocalRepository to encourage not to
use it.

WDYT?

Robert
