At my current client the internet connection works thru a firewall / proxy server.
If I want to install or update the
- ABAP Development Tools for SAP NetWeaver
- SAP HANA Tools
- UI Development Toolkit for HTML5
Eclipse always told me, that it can’t find the update site, even though I’ve followed the instructions on http://scn.sap.com/docs/DOC-28325.
On Stackoverflow I finally found the solution: it seems, that it’s simply an Eclipse bug ( http://stackoverflow.com/questions/5857499/how-do-i-have-to-configure-the-proxy-settings-so-eclipse-can-download-new-plugin ). This is an old question, but the solution still works in Eclipse Kepler.
What you have to do if you also have the problem to connect to the update sites:
As always,follow the instructions on https://tools.hana.ondemand.com/#abap
Next go to Window -> Preferences.
In the section General -> Network Connection, highlight the SOCKS entry and press CLEAR (even if there is NO data yet!). It works on my side without even entering any Proxy settings now.
Restart your Eclipse and try again to install / update the tools.
