Plugin install directory [message #290945] Mon, 05 September 2005 11:54 Go to next message

I have a plugin that needs to find the fully qualified path to a file that
is part of the plugin (it's for an external process). I can't quit figure
a reliable way to do this.

I can cover some cases, but parsing out the bundle location, but that only
works if the "current directory" is the eclipse install directory, which
it's not guaranteed to be. I've not been able to programmatically find the
Eclipse install directory, either.

So is there an approved way to find either a plugin's install directory, or
the eclipse install directory?

Thanks.

You can check the system property "osgi.install.area" (
System.getProperties().get( "osgi.install.area")). It retrieves the
installation directory.

If the file is part of the bundle, then you should be able to call
getBundle().getEntry("/path/to/my/resource") to get the URL of the file.
The path should be relative to the bundle root. To get the bundle install
location, pass "/" as the path.
Once you have the URL, if it is a file: url, you can convert it to a File.

When I call getBundle().getEntry("/").toString(), I get the terribly
unuseful "bundleentry://108/". (At least while debugging...)

So it does. Unfortuately, that turns out not to help when the plugin is
being debugged.

Do you actually need the path to the file or the file contents?
If you really need the file itself, try:

IPath path = new Path ("myfile.txt");
URL resolvedURL = Platform.find(MyPlugin.getBundle(), path);
if(resolvedURL != nul) {
URL realURL = Platform.asLocalURL(resolvedURL);
File file = new File(realURL);
}

Be warned that if you are deploying your plugin as a single jar, this may
not work.

I actually need the file. Well, I could get the contents and then write a
copy out to a temporary directory, but that seems wasteful.

Not a problem yet.

The following is ugly, but works:

1/ here is my plugin:

public class KIDE extends AbstractUIPlugin {

//The shared instance.
private static KIDE fPlugin;

public KIDE() {
fPlugin = this;
}

static final public File getFile(String filename) {
Bundle bundle = fPlugin.getBundle();
URL resource;
resource = bundle.getResource(filename);
if (!BundleUtility.isReady(bundle))
return null;
if(resource==null)
resource = bundle.getEntry(filename);
if(resource==null)
return null;
//String s = resource.getFile();
try {
String path = Platform.asLocalURL(resource).getPath();
File file = new File(path);
return file;
}
catch (IOException e) {
// Auto-generated catch block
e.printStackTrace();
}

return null;
}
....
}


THEN just call something like

java.io.File file =
KIDE.getPlugin().getFile("templates"+File.separator+"bsh");



et hop!
