Eclipse fails to update Maven index while behind company proxy
Eclipse Mars m2e plugin fails to download repository index updates on startup. I run Eclipse behind a company firewall but the proxy settings work fine for "check for updates", "eclipse marketplace", and eclipse's built-in browser. I have tried the following: Deleting the cache directory \eclipse\p2\org.eclipse.equinox.p2.repository\cache and then refreshing the repositories. Preferences -> Install Update -> Available Software Sites => select the entry and click "Reload" Adding -Djava.net.preferIPv4Stack=true to -vmargs in eclipse.ini Edit: Proxy configurations are correctly set in $HOME/.m2
