Email Ant电子邮件IOException

在尝试完成ant mail任务后，我遇到了一个无用的错误。以下是相关代码：

<mail mailhost="smtp.gmail.com" user="blah" password="blahblah" enableStartTLS="true" subject="jMeter test results from nightly build.">
<from address="me@from.com"/>
<to address="me@me.com"/>
<message>This is an automated message containing results from the most recent discovery build.</message>
<attachments>
    <fileset dir="${basedir}">
        <include name="JMeter-Results*"/>
    </fileset>
</attachments>
</mail> 

---

这在过去是有效的，但我把它单独放了几个星期，现在它不起作用了。你知道为什么这不起作用吗？

不知道。可能有一种方法可以打开ant任务的JavaMail会话调试，这可以为您提供出错的线索，或者至少可以帮助您确定这是ant问题还是邮件发送问题
