MPC in RCP application: Unable to read repository [message #1437096]

Fri, 03 October 2014 18:22

Eclipse User

I have added the marketplace client to my RCP application (3.7.1). It seems to work fine at first, the wizard opens and "it" tries to read the repository apparently. However, it fails to load the repo content and the GUI reports an InvocationTargetException.

The console stack trace looks as below.

Is this a case of my application not having the "rights" to access the repo http://marketplace.eclipse.org/catalogs/api/p? Or do I need to add other plugins than the following to make this work?

org.eclipse.epp.mpc.core;bundle-version="1.1.1",
org.eclipse.epp.mpc.help.ui;bundle-version="1.1.1",
org.eclipse.epp.mpc.ui;bundle-version="1.1.1"

I do not have a p2.inf file in my plugin as I want to use the default marketplace.

Many thanks!

I've added .equinox.ds to the dependencies for my plugin (as suggested by another post here in the forum) and now the stacktrace has changed to a number of "[SCR] Error while loading components from DB" errors while the wizard is trying to load the content.

When Cancel is pressed, there is another "[SCR] Error while loading components from DB", followed by an InvocationTargetException caused by an NPE at org.eclipse.equinox.internal.p2.ui.ColocatedRepositoryTracker.getKnownRepositories(ColocatedRepositoryTracker.java:57).

Full stacktrace:

Stephan,

Regarding the original errors, this looks like a problem with your network connection. Can you reach http://marketplace.eclipse.org/catalogs/api/p in a web browser? Do you need to go through a proxy to access the internet and is that configured in Eclipse in "Window > Preferences > General > Network Connections"? A good test for this is to go to "Help > Install New Software" and check if you can retrieve the contents of e.g. http://download.eclipse.org/releases/luna

I don't know about the Equinox DS related issues. In general, you shouldn't need to require DS for MPC versions older than 1.3.0, and 1.3.0 and newer do pull in DS on their own. Again, checking if "Help > Install New Software" works is a good test.

Hi Carsten,

Thanks for your reply. I've found out that this seems to be to do with how the application is started. If started from within the IDE (Kepler), I get the above errors. The same application built with Tycho works fine when started by itself. I get the same behaviour when including .p2.ui.sdk for getting the "Install New Software" behaviour instead of the MPC.
Thanks for your efforts!
