Did some experiment : For some reason -Dmaven.repo.remote=file:/// doesnt have any effect at all ( in maven 3.0 ) However the same can be given in settings.xml
However, it wont result in a read-only local repository, as the artifact gets copied from teh file:/// location to teh location designated as local repository ( But since it is a file to file copy, it is fast ) But thats fine, since the real problem is about the local repository being unsafe for concurrent access. So thanks for that. --sony On Fri, Apr 15, 2011 at 4:06 PM, Sony Antony <sony.ant...@gmail.com> wrote: > Thanks a real lot James : > I was not aware of maven.repo.local ( although I was aware of teh > setting.xml optio to specify the local repository ).
