Have been using the latest and greatest eclipse helios for quite some time, but recently had to switch back to eclipse ganymede because the latest flash builder 4 was not compatible with helios. Although I did had ganymede on my system, which was stuffed with too many plugins including the old version of m2eclipse, I thought of starting with a fresh installation of eclipse ganymede with the latest version of m2ecilpse over it. But as soon as I entered the m2eclipse update site ULR: http://m2eclipse.sonatype.org/sites/m2e, it started to give “No repository found at http://m2eclipse.sonatype.org/sites/m2e” error.
A little bit of googling and I found this:
http://blog.gmane.org/gmane.comp.ide.eclipse.plugins.m2eclipse.user/month=20100701
In short, use http://m2eclipse.sonatype.org/sites/archives/0.10.2.20100623-1649/
instead of:
http://m2eclipse.sonatype.org/sites/m2e
if you are using eclipse 3.4.x

thanks a lot posting FIX on how to install maven plug-in for eclipse 3.4
I’ve been frustrated not being able to install the plug-in with error “No repository found at http://m2eclipse.sonatype.org/sites/m2e”.
the official site http://m2eclipse.sonatype.org/installing-m2eclipse.html is toatally useless.
After using the URL you posted, I can able install in 5 minutes. Thanks for saving my day !!
