JavaMail smtp.gmail.com ANT vs Eclipse

Question

我遇到了一个非常令人沮丧的代码问题，该代码试图通过gmail通过JavaMail发送电子邮件。我的代码在Eclipse中运行时可以工作，但当我运行Ant时，它无法连接，并出现"Cannot connect to SMTP host，repense-1"错误。

我在Eclipse和Ant中使用相同的JRE，从类路径的角度看没有任何不同。

JavaMail调试日志如下——首先是在Eclipse中成功运行；

DEBUG: JavaMail version 1.4.2
DEBUG: successfully loaded resource: /META-INF/javamail.default.providers
DEBUG: Tables of loaded providers

现在是Ant的失败运行；

有什么想法吗？

您是否在与从Eclipse运行时相同的机器上从ant运行？JavaMail常见问题解答提供了连接调试提示。此外，您使用的是非常旧的JavaMail版本；如果可以的话，升级到当前的1.5.5版本。
