I try all solution on the internet but no result, it's seems that my eclipse won't connect to internet, every time i try to install for example new softwares i have error message:
Unable to read repository at http://download.eclipse.org/releases/luna/content.xml. Unable to read repository at http://download.eclipse.org/releases/luna/content.xml. Address family not supported by protocol family: connect
I spend hours on this problem :(
any help will be appreciated
The problem for me was that on apache-maven-3.2.5\conf\settings.xml i have a proxy, so i delete it and every thing works fine
