How to get file location from a BundleDescription [message #85769]

I am able to retrieve the location via getLocation() but I need
something that can be used to create a File object and not "update@../".

Thanks!

You shouldn't assume that there's a File location available. You can use 'getClass().getResourceAsStream()' to load the contents. If you need a File for legacy API usage, then extract a copy to the PluginStateLocation first.

Thank you for the fast response. I am trying to find away to locate the
plug-ins mentioned in the .state files in configuration directory. I am
reading in the State and looking at the bundle Descriptions using
StateObjectFactory. Unfortunately there doesn't seem to be a pointer
from the configuration directory back to the Eclipse Directory. Do you
know of any?

The configuration directory isn't really used for configuration. It's more like the equinox work area.

Plugins access state using the Plugin.getStateLocation() directory.

http://help.eclipse.org/help32/topic/org.eclipse.platform.do c.isv/reference/api/org/eclipse/core/runtime/Plugin.html#get StateLocation()

That will create you an IPath, and then you can put whatever files in there that you want.

Let me take a step back. I am writing an application to diagnose Eclipse
Instances on the User's computer. I have been using the configuration
directory since I can gather Bundle Information and find missing
dependencies without starting the Eclipse Instance.

Thanks.

Ah, so you're probing internal state of the configuration directory to do some specific Equinox-probing; right. I don't think there's any exposed API to deal with that, but I could be wrong; you might get better results (if no-one else replies here) by posting a message to the equinox-dev mailing list.

It looks like the getLocation() method of the BundleDescriptor returns a
relative path. So if I can figure out whhich eclipse instance used a
configuration directory, I may be able to put the 2 together. However I
cannot find any pointer in the configuration directory back to the
Eclipse executable. Do you know of any?

The getLocation method of BundleDescription returns the location string
used to install the bundle. This string can be anything, there is no
requirement for it to be a real path. That being said the paths in the
location are by convention relative to the eclipse installation. The
real path information for the bundles is stored in the .bundledata file
in the org.eclipse.osgi configuration cache. There is currently no api
for reading this internal data structure.
