What I found is some library that cannot be found (i do not know who is needed it, but this is the only problem that I can see there):
org.osgi.framework.BundleException: The bundle "com.sap.it.nm.commands_1.11.0 [1456]" could not be resolved. Reason: Missing Constraint: Import-Package: com.sap.it.commons.command; version="[0.0.0,1.0.0)"
This may be a result from interrupted installation, so please do a clear install by following the instructions:
1. Create new folder.
2. Download the Eclipse Kepler from:
https://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/keplersr2
3. Unzip and start eclipse in this new folder.
4. When ask for workspace on Eclipse point to completely empty folder (is better if you create new one next to eclipse installation).
5. Use following update site to install your tools:
https://tools.hana.ondemand.com/kepler
This should bring you a clear installation and should work.
From logs I see that you do not need to set proxy, as you are directly connected to internet.
Enjoy,
Dobri
