noob question / installing STS 2.7.1 / ubuntu 10.10 problems

Hi

I am trying to install STS 2.7.1 on Ubuntu 10.10 and have some problems.
The installation seems to have gone straightforward, but e.g. trying to create and build a simple Spring Template project gives errors like:

7/25/11 8:59:16 AM EDT: Missing artifact org.springframework:spring-test:jar:3.0.5.RELEASE:test

7/25/11 8:59:17 AM EDT: Missing artifact org.springframework:spring-asm:jar:3.0.5.RELEASE:compile

What am I doing wrong?

Thank you

When I try to import and build sample projects from "Spring Recipes" I also get errors like:

I started to wonder if I have to set an HTTP proxy variable for STS somewhere other than in system http_proxy environment variable? Otherwise on this machine, other apps (apt-get, browser, etc.) seem to get out through the HTTP proxy/firewall just fine (and I have set this env variable).

Thank you

STS uses the system proxy setting if the proxy provider is set to "Native" in the preferences under General > Network Connections.

For m2e, which provides the Maven integration for STS, you need to set separate proxy settings that are configured through Maven's setting.xml:
