Re: [m2e-users] unknown format version: -9 ?

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

The exception comes from reading local lucene index, which should be
unrelated to the transport format. Looks like your local lucene index
got corrupted.

m2e caches lucene index in two places. Per-workspace indexes are stored
under .metadata/.plugins/org.eclipse.m2e.core/nexus and there is also
global cache in ~/.m2/repository/.cache/m2e/${m2e.version}.

Try cleaning the caches and see if the problem goes away.
