问题 I'm trying to get a Tycho build to work on an OpenShift server. Locally resolving the target definition and building works fine, but when deploying I get the following error: Unable to read repository at http://download.eclipse.org/rt/rap/2.2/content.xml.

Could someone tell me what the problem is

问题 When trying to add a Software Site (p2 plugin repository - either one generated by p2 Publisher or Nexus with p2 support) to a target definition via the "Target Definition Wizard" there seem to be "no items available" preventing the site to be added.

问题 When I tried to update Eclipse to the latest SR2, I got a download rates around 10kb/s - which means I couldn't even get the content.jar . Which means I need to setup a mirror for the other 10 developers. What is the most simple (= less than one day of work) and reliable (= automatic, scripted) way to do this?

问题 When building a product based on Eclipse 3.7+, I want to include a marketplace feature (org.eclipse.epp.mpc).
