JavaMail smtp.gmail.com ANT与Eclipse

Question

I have a very frustrating issue with code that's trying to send an email through JavaMail via gmail. My code works when run from Eclipse, but when I run through Ant it fails to connect with a "Could not connect to SMTP host, reponse -1" error.

I'm using the same JRE's in both Eclipse and Ant and don't see anything from a classpath perspective that is different.

The JavaMail debug logs are below - first the successful run from within Eclipse;

DEBUG: JavaMail version 1.4.2

...and now the failed run from Ant;

Any ideas?

Are you running from ant on the same machine as when you run from Eclipse? The JavaMail FAQ has connection debugging tips . Also, you're using a very old version of JavaMail; upgrade if you can to the current version 1.5.5.
