Jenkins要做到构建失败的时候发送邮件，常规做法是加个全局的post failure，类似这样的代码
pipeline {
agent any
stages {
stage('deploy') {
steps {
script {
error 'failed';
}
}
}
}
post {
always {
echo 'This will always run'
}
success {
echo 'This will run only if successful'
}
failure {
mail bcc: '', body: "<b>Example</b><br>Project: ${env.JOB_NAME} <br>Build Number: ${env.BUILD_NUMBER} <br> URL de build: ${env.BUILD_URL}", cc: '', charset: 'UTF-8', from: '', mimeType: 'text/html', replyTo: '', subject: "ERROR CI: Project name -> ${env.JOB_NAME}", to: "foo@foomail.com";
}
unstable {
echo 'This will run only if the run was marked as unstable'
}
changed {
echo 'This will run only if the state of the Pipeline has changed'
echo 'For example, if the Pipeline was previously failing but is now successful'
}
}
}
这种做法有一点不好之处就是有几个JOB 需要发邮件就需要写几份发邮件代码，对原来Jenkins代码也有侵染。
有一种办法可以避免这样的情况，新建一个JOB ，这个JOB名字就叫做发邮件，把这个JOB 设置为上游JOB 触发，意思是当需要发邮件的JOB 在构建完以后，不管成功失败都会触发发邮件的JOB，来实现统一发邮件。
1.新建pipeline JOB, 在‘其它工程后触发’ 这里填上你想要发邮件的job,如果有多个使用逗号分隔 .
2.pipleline 的代码
pipeline {
agent any
stages {
stage('deploy') {
steps {
script {
String buildResult = "";
String buildNumber = "";
String jobName = "";
(buildResult, jobName, buildNumber) = getUpstreamBuildResult();
String buildUrl = "http://localhost:8080/job/${jobName}/${buildNumber}/console"
if (buildResult == 'FAILURE') {
echo "send email";
mail bcc: '', body: "<b>Example</b><br>Project: ${jobName} <br>Build Number: ${buildNumber} <br> URL de build: ${buildUrl}", cc: '', charset: 'UTF-8', from: 'tianhe1006@126.com', mimeType: 'text/html', replyTo: '', subject: "ERROR CI: Project name -> ${jobName}", to: "jonas.tian@activenetwork.com";
}
}
}
}
}
}
def getUpstreamBuildResult() {
def upstream = currentBuild.rawBuild.getCause(hudson.model.Cause$UpstreamCause)
String jobName = upstream ? .getUpstreamProject();
echo jobName;
String buildNumber = "${upstream?.getUpstreamBuild()}";
echo buildNumber;
def upstreamTriggerBuildResult = Jenkins.instance.getAllItems(AbstractItem.class)
.findAll {
it.fullName == upstream.getUpstreamProject()
}
.collect {
proj - > proj.getBuilds().findAll {
it.number == upstream.getUpstreamBuild()
}.collect {
it.getResult()
}
}
.flatten()[0];
echo "${upstreamTriggerBuildResult}";
return [upstreamTriggerBuildResult, jobName, buildNumber];
}
注意一点，这里用到了不安全代码，需要手动approve,运行一次，就会看到报错，一直点approve 就好了，但是如果不想这么麻烦可以安装一个插件
Permissive Script Security Plugin
https://wiki.jenkins.io/display/JENKINS/Permissive+Script+Security+Plugin
安装这个插件后就可以自动approve 不安全代码。
