Eclipse cannot debug. Please help I tried everything

Question

Whenever I try to open the debug perspective, I get this message and the problem is that it disappears immediately before I can even check deny or allow. I can run the program, but I cannot debug.

I run OS X 10.8.5

Things I tried, but all failed

1. I have tried to uninstall and install Eclipse, but that did nothing.
2. I tried adding Eclipse to my firewall exceptions and checked "allow incoming connection" in Security and Privacy, but that did nothing.
3. I have tried following the instructions mentioned here.

But no help at all.

Answer 1

One "security" tempering I didn't saw in the link you reference in your question is:

• removing Eclipse from the firewall list of apps
• removing Eclipse from the plist files.

A plist is a special kind of text file that contains properties the application and other resources, typically the OS, use to retain and reuse information needed to run the application.
plist is a file type and has many uses, typically storing user preferences, but, essentially, it is an XML file. You can look to see if there are any caches, which are typically plist files, for the applications in question in /Library/Caches and /System/Library/Caches.

Answer 2

Checking on that particular error message, it seems to be caused by issues with the firewall configuration. I am not sure if it will help, but I would verify that the program is allowed to access your network. Check in System Preferences > Security & Privacy > Firewall > Firewall Options. You should be able to allow your app to access the network from there. Hope this helps!
