Interrupt deletion action/command from IProject [message #719504] Sat, 27 August 2011 14:28

Hi all,

some fellow students and I are working on an eclipse plugin for code
reviews (AgileReview). Therefore all review data are stored in a
IProject having its own project nature.

In order to prevent the user from deleting the current necessary folder
for the plugin, we want to interrupt the deletion of the project.

We tried this by using an IResourceChangeListener, but unfortunately we
cannot find any interruption method. Then we tried to catch the command
with an own handler in order to avoid the deletion and inform the user.
For the shortcut “del” everything worked fine, but selecting delete over
the popup menu, the deletion will be performed and the specified handler
is ignored.We think this is due to the implementation, that the command
org.eclipse.ui.edit.delete is only a wrapper for the action used in the
popup menu of a IResource.

Google does not help us anymore. Is there a way to interrupt the delete
command/action in a given context (IProject with a specific
projectNature) or simply redirect it to a new handler like it worked
successfully for the shortcut “del”?

Hope, someone can help,

Best regards,
