执行ant邮件任务时收到错误消息"java.lang.ClassNotFoundException： javax.mail.internet.MimeMessage"

Question

我试图执行下面提到的ant邮件任务，我收到错误消息：java.lang.ClassNotFoundException: javax.mail.internet.MimeMessage。

我为蚂蚁创建了环境变量。

还放置了mail.jar、activationjar&在lib文件夹中以及在eclipse -> preferences -> Global Entries中的ant javamail jar。执行ant邮件任务还需要什么？请提出建议。

<target description="Generates and send TestNG test reports" name="send-report">
    <mail mailhost="smtp.sears.com" mailport="25" user="kmartvlakshm" password="AK230211$$" ssl="true" subject="Test build">
    <from address="[e-mail]"></from>
     <replyto address="[e-mail]"></replyto>
     <to address="[e-mail]"></to>
     <message>Please find the attached report for Sears International smoke test results.</message>

           <fileset dir="C:\Documents and Settings\vlakshm\workspace\INTL_REG\test-output\emailable-report.html">
            <include name="**/*.zip"/>
           </fileset>
         </attachments>
      </mail>
    </target>

在命令提示符下，执行下面提到的命令

ant send-report

获得下面提到的异常

Answer 1

在ANT_HOME/lib中添加mail.jar和activation.jar，或者在项目/lib中同时使用这两个jar
