已在 Jenkins的 job-構建后操作設置了郵件發送通知：（但是發送不成功，且報錯）
1、跑完工程后，發送郵件觸發失敗 ？
Email was triggered for: Failure - Any Sending email for trigger: Failure - Any An attempt to send an e-mail to empty list of recipients, ignored. Finished: FAILURE
2、使用上一次跑的測試報告index.html（因為跑一份新的需要1個多小時，成本太大，），來打包發郵件，會報這個錯誤：
+ zip -r report.zip test-output/index.html
updating: test-output/index.html (deflated 96%)
Recording test results
ERROR: Step ‘Publish JUnit test result report’ failed: Test reports were found but none of them are new. Did leafNodes run?
For example, /Users/XXX/.jenkins/workspace/YYY-project/test-output/index.html is 23 分 old
Email was triggered for: Failure - Any
Sending email for trigger: Failure - Any
An attempt to send an e-mail to empty list of recipients, ignored.
Finished: FAILURE
這個問題找到解決辦法：
Jenkins在執行JUnit報告時報錯Test reports were found but none of them are new. Did leafNodes run? 問題解決：

——提到說，如果測試運行和JUnit插件運行間隔超過3秒，則插件將忽略這些文件。
——解決辦法：更新這個文件的時間
3、同時需要確保已經配置了 "Extended E-mail Notification"
—— inspired by 【
Jenkins Email sending fails 】
（在Jerkins-->Manage Jenkins -->Configure System -->"Extended E-mail Notification" 中進行配置 ）
——Extended E-mail Notification Plugin 插件的詳細講解
設置了郵箱之后，又報這個錯：
+ zip -r report.zip test-output/index.html
updating: test-output/index.html (deflated 96%)
Recording test results
ERROR: Step ‘Publish JUnit test result report’ failed: Test reports were found but none of them are new. Did leafNodes run?
For example, /Users/yyy/.jenkins/workspace/CXXX/test-output/index.html is 1 小時 39 分 old

4、根據另一個接口自動化的Jenkins任務，參考其具體的配置，對此UI自動化工程進行配置，如下：
在：Jenkins --系統管理 --配置系統。
4.1）Jenkins Location
4.2）Extended E-mail Notification
4.3）郵件通知
5、build #55 又發生下面這個錯： —— Publish Junit test result report的問題，換成 Publish HTML Report 就不會報此錯了。（詳見：Jenkins安裝 HTML Publisher plugin插件）
+ zip -r report.zip test-output/index.html
adding: test-output/index.html (deflated 94%)
Recording test results
ERROR: Step ‘Publish JUnit test result report’ aborted due to exception:
org.xml.sax.SAXParseException; lineNumber: 670; columnNumber: 36; 在實體引用中, 實體名稱必須緊跟在 '&' 后面。

at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1472)
6、出現的終極大問題：
【SendFailedException message: 451 5.7.3 STARTTLS is required to send mail [SHAPR01CA039.CHNPR01.prod.partner.outlook.cn] 】
按照對應的內容配置好了，項目構建也成功了，發送報告郵件的時候，報錯。
百度了這個錯，並沒有找到，最后通過FQGoogle找到的一個回答是：
需要去修改Jenkins啟動命令文件，在該文件中加一句命令： -Dmail.smtp.starttls.enable=true
可是找到這個一個類似的文件：是jenkins_runner.sh，發現它里面已經有上述的那句命令了……（暈了）
所以，這個也解決不了……
7、問了下IT負責人，建議SMTP服務器和端口換一個試試，於是試了如下：
smtp服務器：XXX-com.mail.protection.partner.outlook.cn
端口 25
——然后測試郵件發送就可以了！！！
