Hi,
I'm porting a plugin from Eclipse 2.1.3 to Eclipse Platform Version: 3.0.0
Build id: 200405211200, wading through the now deprecated method calls.
I'm having difficulty with this one:
MyPlugin.getInstance().getDescriptor().getInstallURL()
- getDescriptor() is now deprecated, but there's no alternative route
suggested by the documentation.
The reason I need the install URL is because there are other configuration
files shipped with the plugin which need to be read. These files all sit
in a directory (standardProfiles) off the plugin's install directory, and
a loaded after doing a directory listing.
Using some code adapted from AbstractUIPlugin.imageDescriptorFromPlugin:
Bundle bundle = Platform.getBundle(PLUGIN_ID);
if (!BundleUtility.isReady(bundle))
return null;
URL fullPathString = BundleUtility.find(bundle, "standardProfiles");
if (fullPathString == null)
return null;
... I always find that the URL is "/standardProfiles" which is no help.
What's the proper way to locate a directory off the plugin's install
directory?

Have a look at Platform.asLocalURL to get a full path to the directory.
All Bundle related functions give pathes relative to the platform or the
plugin itself.

Please do not use asLocalURL unless you really need it. It will make a
local physical copy of the file if it is not a local file.

The best way to find it is to use Platform.find(bundle, new
Path("standardProfiles")).
That way it will look in fragments too.
This will return a strange looking url that has a protocol of bundle:,
but this is ok. This url will work if you intend to use it as a url.
The better way to get your configuration files is to use
Platform.find(bundle, new Path("standardProfiles/yourconfigfile"))
for each config file, and that way you will get a URL directly to the
config file itself. Then to get the contents of the config file you
would simply do openStream() against the URL. That way it will work no
matter where the file is. (You see in the future files in the plugins
may actually be on another system, or the entire plugin may be zipped up
into a jar, the bundle: protocol handles this).

Guillaume,
That works. Thanks for your help.
