Re: [p2-dev] List of update sites

1). When you start a Launch Configuration if you don't have any repositories listed in your preferences under Install/Update -> Available Software Sites then the list returned by the API will be empty.

2). In older versions of Eclipse you can get the service through the bundle context and not go through the agent. Like you said, the agent was a concept introduced in 3.6.

Thanks for the point,

I've got two questions:
1. When I launch my plugin in PDE mode, array returned by IRepositoryManager.getKnownRepositories(IRepositoryManager.REPOSITORIES_ALL) is empty. Is that expected? (maybe because installing features are not avaliable in PDE launch? Can I turn them on?)
2. IProvisioningAgent seems to be Eclipse 3.6-only class. Is there something that is 3.5-compatible (or maybe even 3.4)?

It is a service so you can acquire it like any other OSGi service.
The code should look roughly like:

ServiceReference reference = context.getServiceReference(IProvisioningAgent.SERVICE_NAME);
if (reference == null)
return null;
try {
return context.getService(reference);
} finally {
context.ungetService(reference);
}

Where "context" is your BundleContext object available from your bundle activator.

Jacek is correct. You can do a service look-up via the agent.

IProvisioningAgent#getService(IMetadataRepositoryManager.class.getName());

Anyway, a bit of goolging pointed to IRepositoryManager interface, that should do what you want. Although I'm not quite sure how to obtain reference to it.


2011/3/25 Jacek Pospychała <jacek.pospychala@xxxxxxxxx>
one option is via use of p2.inf files, e.g.:

instructions.configure=\

  addRepository(type:0,enabled:false,location:http${#58}//download.eclipse.org/releases/helios);\

  addRepository(type:1,enabled:false,location:http${#58}//download.eclipse.org/releases/helios);

you can put p2.inf file in a feature, or a plugin (META-INF folder).

There's some limitations though - e.g. you can't set update site name.

And there's some bugs, which may make your update site not added, e.g. in Windows 7

Hi,

Is there a way to get list of configured update sites (those seen in
"Avaliable Software" dropdown in "Install" dialog) programmatically?

Thanks,
Andrey
