Subject Re: issues when disabling settings.xml
Date Tue, 24 Sep 2013 13:49:54 GMT
Maven keeps track of the source of the artifacts that it downloads.

When you swap out your settings.xml, then the source changes from your
corporate proxy to maven central.

Thus Maven expects that the artifacts in the cache may no longer even exist
or may be different.

Maven therefore tries to re-download at least the checksums and potentially
the artifacts themselves.

The legacy-local-repository switch disables the origin checking, similarly
by putting a proxy between you and the actual source of the artifacts you
convince Maven that everything is coming from where it got them last time,
so it will remain happy trusting the artifacts are from the source it knows.
