I need to build the mozilla source in my Windows 7 machine. I used the following command line code to pull the source using mercurial
hg clone http://hg.mozilla.org/mozilla-central/ D:\FFsrc\src20
but the process always stop in the middle, with the following error.
requesting all changes adding
changesets transaction abort! rollback
completed abort: premature EOF reading
