You can manually reset password and email. Just find:
\7.3\config\Preferences\org\netbeans\modules\j2ee\appengine\deployment.properties
and clear it. Then GAE plugin will ask for the password and email via a dialog box.
But you are right. The plugin might support such a feature. I will try to do this for Netbeans 7.4 (and of course for 7.3.x).
If you have any other ideas on this subject, please report
Thanks..
I believe this has been noted online already but is not yet done.
1) After entering an app Engine email and application specific password you cannot reset/or change it.
2) I would also recommend also having a email/password on a per project basis as well. for those that work with different clients apps.
