Quick diagnostic summary tied to the posts above: the combination of "Unable to read repository" and the Java socket error "Cannot assign requested address: connect" usually means Eclipse's JVM cannot open an outbound TCP connection to the update host (network/route/DNS issue, local host mapping, or something on the machine intercepting Java traffic), not that the repository itself is definitely down. and were right to ask for the exact address, and correctly pointed toward network/permission causes — below are focused, practical steps to narrow it down.

Try these quick tests outside Eclipse (replace <host> with the hostname shown in your error message):

ping <host>
nslookup <host>
tracert <host>
curl -I http://<host>/     # or open the same address in a web browser

What the results mean:

  • DNS/ping/tracert fail → routing or DNS problem (or hosts file mapping). Check your hosts file for accidental entries and any active VPN/virtual adapters.
  • Browser reaches the site but the above tools (or Eclipse) fail → something is intercepting JVM/HTTP traffic (corporate proxy, security appliance or endpoint AV that hooks Java).
  • Browser also fails while other sites work → broader routing/DNS issue on the machine or network.

A couple of practical, non-duplicate notes not yet in the thread: double-check the URL you typed for trailing punctuation or spaces (forum output sometimes shows a trailing dot after content.xml), and if Eclipse is installed under a protected folder, try a fresh portable copy extracted to a writable folder (e.g., C:\eclipse) to rule out permission/UAC write-protection without needing to change system ACLs.

Next useful info to paste here if you want more help: the tail of workspace/.metadata/.log around the timestamp of the failure, the OS, the output of java -version used by Eclipse, and the exact results of the commands above. If you need a short workaround while debugging, download the update-site archive with a browser (if reachable) and install from local archive or use the dropins folder.

ehm ... you may have given a wrong url. there may be problems with your internet connection, ....
but without giving a bit more information, it's pretty difficult to give a more profound answer.

Nobody can help unless you are prepared to give a lot more information. Eg Which version of Eclipse? Is this all plugins? Just one plugin? Which one, exactly? Ignoring peoples' questions will get you nowhere.

OK, that helps to narrow it down!

  1. Check Eclipse's proxy settings - should use system default
  2. Check firewall isn't blocking Eclipse
  3. Try running Eclipse as administrator
  4. Could be an IPv6 problem, Try updating eclipse.ini
    under line -vmargs add this line:
    -Djava.net.preferIPv4Stack=true
  5. Update to the current release (Juno SR1) and try again

when i edit the eclipse.ini file..
it says "ACCESS DENIED"

now what ?

Member Avatar for JamesCherrill

Is Eclipse open? If not, this looks like an access privileges problem - try running as administrator, or change the security on the eclipse folder to allow full control for all users.
