ADT Bundle for mac is damaged

Question

I download the ADT Bundle for mac and save it under /development. When I try to open eclipse, my mac says "Eclipse" is damaged and can't be opened. You should move it to the Trash. I trash the whole thing and tried downloading again, I get the same error. Does anyone know a fix for this? My mac is osx 10.8.3 processor 3.1 GHz Intel Core i5.

FYI: I removed an old eclipse folder from /Application before doing above. Could the older deleted juno eclipse (Version: Juno Service Release 2) be causing some interference?

Answer 1

This bug is related to the signing of the app and Gatekeeper.

"Damaged" app. – The app has been altered by something other than the developer.

The bug is also reported in Eclipse Bugzilla

An easy fix (as suggested by #2 comment in the above bug report) is disabling Gatekeeper temporarily. Visit System Preferences > Security and Privacy > Select "Anywhere" in "Allow Applications downloaded from:". Now run the app and you can enable Gatekeeper again.

Answer 2

I found a workaround here, in the command line go to the directory containing the Elicpse.app directory and execute

xattr -d com.apple.quarantine Eclipse.app/

the problem seems not to be solved anyway
