determining Eclipse or Eclipse plug in location at run time [message #461508]

Hi ,

I have a plug in and need to save some user information . To do this I
was thinking of using a File , but I need to specify the location of the
file . I want the file to ideally be in the same folder as my plug in (
.../eclipse/plugins/MyPlugin)

Basically I need a mechanism where I am storing this file under MY plugin
directory.

Is there an API or mechanism that provides the location of the currently
running plugin ?

I am running on Linux and When i check for the current working directory
it returns /root

Thanks

Yeah, and to follow it up, you shouldn't assume that (a) myplugin is a directory, or (b) that it's writable. You certainly shouldn't expect to get out resources via a java.io.File object.

Look for the getPluginStateLocation(), and if you need to instantiate a template, access it from the plugin with getClass().getResourceAsStream("/the.template.txt"), then pass that to whatever stream is expecting to read from it. You can then dump it out to the plugin state location later.

Thank you everyone for the responses . I had one question regarding the
process of Writing

You were suggesting that I not use java.io. classes

How would i write to this same resource ?

I think Alex was saying for reading defaults or templates out of your
plugin, don't use java.io.File, just use getResource(*) or
getResourceAsStream(*).

To write to your plugin state location, it's OK to use java.io.File,
Writer, etc.
