How tro obtain the absolute install path of a plugin? [message #253886]

Hello,

I can't obtain the absolute install path of my plugin. I didn't find any
suitable methods in class Platform. I've tried
IPLuginDescriptor::getInstallURL() but the returned URL is :
"/plugin/my_plugin_directory/" (I don't understand this URL because my
plugins are stored in the "plugins/" directory of the platform and the URL
contains "plugin/" (without 's'). So this URL is even not the relative
path of my plugin in the platform?)
What I want to do is accessing directly to a resource stored in my plugin
directory.

thanks in advance
Fabien

Hi,

there is a method in Platform called "resolve" which resolved the URL
retrieved by getInstallURL. A call to ".getFile()" of the retrieved URL
gives you the absolute path on your system---like this:

String resolvedPath = Platform.resolve(<URL retrieved by
PluginDescriptor.getInstallURL()>).getFile();

Note however, that PluginDescriptor is deprecated in 3.0. I am not too
sure about it, but I _think_ the correct way to determine the installation
path of a plug-in in 3.0 is:

private String getResolvedPath(String pluginID) {
Bundle bundle = Platform.getBundle(pluginID);
if (bundle != null) {
URL bundleURL = bundle.getResource("/");
if (bundleURL != null) {
String resolvedPath;
try {
resolvedPath = Platform.resolve(bundleURL).getFile();
return resolvedPath;
} catch (IOException e) {
}
}
}
return null;
}

where "pluginID" is the id of your plug-in as defined in plugin.xml.

Hope that helps,
Philipp

But be aware you may not always get a file url. It is possible,
depending on how things are installed, that you could get a URL pointing
into a jar, or even a url that exists on another system.

However, the default is currently a local file. Most installations don't
have the plugins zipped into a jar nor do they install remote.
