How can I get the path of the project [message #519293]

Hello, I'm developing a plug-in for Eclipse. I want to save some folders inside the project to use it when it will be published.

The problem is that I don't know how to get the path in will it be the plug-in when it's going to be "installed" on the eclipse. So, how can I get that path?.

For example..the answer I need at get the path in windows would be:

c:\eclipse\plug-ins\myplugin\folderIwanttouse....

or something similar...the problem is that I don't know the first part of the path...

Thank you!

You can retrieve the location of a plugin using: Platform.getBundle("myplugin").getLocation()
and you can also get the URL of included folders and resources using: Platform.getBundle("myplugin").findEntries("folder", "*.jpeg", true). Keep in mind that the URL it returns may be bundleresource:// urls, so that you'll probably have to use FileLocator.toFileURL on them.

In my case I had to create a directory Template in the Workspace directory. To do this i use this code:

		
String templateAbsoluteRoot = Platform.getLocation().toOSString() 
			+ PlatformUI.getPreferenceStore().getDefaultString(PreferencesUtils.SEPARATOR)
			+ PlatformUI.getPreferenceStore().getDefaultString(PreferencesUtils.DIR_TEMPLATE);
File templateD = new File(templateAbsoluteRoot); 
		if( ! templateD.exists() )
			templateD.mkdir();

Remember the dependence

org.elcipse.core.resources

in your plugin.xml

Hello, thank you so much.

I have tried to use:
Platform.getBundle("myplugin").getLocation()

the problem, is that I don't know how to put like the string of getbundle... I have seen my plugin.xml and I have the id of the plugin...also the name....

I have tried with both and it didn't work...

I must missing something...what?

I also has though about add the dependence that says Luca Gallici on the plugin.xml but I don't know where....in it

See what Mickael wrote. Bundle#findEntries(*) and Bundle#getEntry(*)
can give you access to folders that are in your plugin. Consider this a
read-only location.

Then the question becomes what to do with them. To copy them out for
use, simply get the InputStream and away you go.

If you are using a legacy API that needs a java.io.File (as opposed to
an InputStream) then use FileLocator.toFileURL(*) to make sure you have
a file that you can use (FileLocator even copies it out to a temporary
location if necessary).

Thank you Paul Webster, but the problem is that I don't know what to use in:

Platform.getBundle("myplugin").getLocation()

What I must put on the "myplugin" string?

I have tried with the id wizard or name wizard that it's on the plugin.xml, but the execution stops a that time.

I suppose once I have this fixed, I only must use the methods you say to access to the folder I want.

Thank you!

You have to put the id of the plugin. It is the value of Bundle-SymbolicName that you can read in your MANIFEST.MF.

A lot of thanks!

It works perfectly. I have seen that the path I get is the path of the myplugin project in the workspace. I suppose that if it's would be installed the path will be indicates the folder of the plugin inside de eclipse folder, won't be?.

1) it must be the Bundle-SymbolicName (as mentioned by Mickael) from
your MANIFEST.MF file (check in the MANIFEST tab if you have the PDE
editor open). There shouldn't be a relevant ID in your plugin.xml

2) do you run with a workspace? Either a real workspace (because you
use org.eclipse.core.resources), or try simply -data
/path/to/a/temp/workspace
