I have Eclipse 3.6 with m2eclipse (Maven's plugin for Eclipse) 1.1, it works.
And now I want to try m2eclipse version 1.4, I upgrade it directly and find I cannot see Maven in any menu. Then I try to uninstall and re-install it but I always get this message and Eclipse doesn't install anything.
Your original request has been modified.
"m2e - Maven Integration for Eclipse" is already present because other installed
software requires it. It will be added to the installed software list.
Finally, I try to search all files contain "m2e" and delete them from Eclipse's directory, but still get the same message, any suggestion to un-install m2eclipse?
ps: I use Eclipse Help > About eclipse > Installation details to un-install and restart to make sure m2e is not in Eclipse before re-install. I also use -clean parameter but still the same.
