How can an Eclipse plugin access the project direc

Question

Is there a way to get the directory of a project in Eclipse? We are writing a plugin that will allow the user to select files, and then run some processes on those files. I would ideally like to be able to get all the files with a certain extension, but that is not necessary.

Answer 1

If you want to enable your users to select files inside eclipse workspace with a certain extension, you can look at the class org.eclipse.ui.dialogs.ElementTreeSelectionDialog (org.eclipse.ui.dialogs plugin)as a start.

Then, to have an example on how to make it filter extensions, you can look at the class org.eclipse.jdt.internal.ui.viewsupport.FilteredElementTreeSelectionDialog (org.eclipse.jdt.ui plugin) to see how they do it and then reimplement the stuff.

This should give you a higher level of action than going threw files inside projects by hand and reimplement dialogs.

Answer 2

sure:

ResourcesPlugin.getWorkspace().getRoot().getProjects()

will get you a list of all the projects in the workspace. you can easily iterate to find the one you want. At that point, you can look for certain files by extensions, etc.
