使用jenkins发送电子邮件得到以下错误响应

Question

这里我提到了电子邮件阶段def subject="作业$｛buildStatus｝-$｛env.Job_NAME｝-生成

${env.BUILD_NUMBER}"
echo "env variable running"
echo "${subject}"
def summary = "${subject}"
echo "${summary}"
def details = """ Your Job's build has been ${buildStatus}. Click the URL to view the build log. nn ${env.BUILD_URL} nn Sent from JustOps.io"""
echo "${details}"
mail to: "[e-mail]",
subject: "${summary}",
body: "${details}"

我收到以下错误执行成功后条件时出错：

Answer 1

这是由于底层JavaMail没有为mime类型配置。JavaMail 1.1.3中提供了html处理程序，但没有为此配置mailcap文件。尝试添加以下行-

text/html;; x-java-content-handler=com.sun.mail.handlers.text_html

Answer 2

在脚本管道中，您可以执行类似于以下的操作

import javax.activation.MailcapCommandMap;
import javax.activation.CommandMap;
@NonCPS
def setupMail(){
MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content- handler=com.sun.mail.handlers.message_rfc822");
}
node {
setupMail()
mail(   from: '[e-mail]', 
replyTo: '[e-mail]', 
to: [e-mail],
subject: "Hi there MIME",  
body: "It Works!")
}
