通过电子邮件发送Jenkins错误日志（无法提取日志的错误部分）

Question

我需要提取jenkins日志中仅包含错误描述和堆栈跟踪的部分，以便我可以在电子邮件中发送它（我使用管道中的jenkins电子邮件文本插件来完成）。

例如，在下面的日志片段中，我需要“org.jenkinsci.plugins.scriptsecurity”之后的所有行

    ...
    Sending build end EMAIL
    [Pipeline] echo
    Build Number: 218
    [Pipeline] }
    [Pipeline] // stage
    [Pipeline] }
    [Pipeline] // withEnv
    [Pipeline] }
    [Pipeline] // node
    Scripts not permitted to use method hudson.model.Actionable getAction java.lang.Class. Administrators can decide whether to approve or reject this signature.
    [Pipeline] End of Pipeline

我怎样才能做到这一点？我将感谢任何帮助

这是我的管道结构:

       pipeline {
         agent {...} 
         environment {...}
         stages {...}
         post {...}
       }

Answer 1

一种方法是将整个管道脚本包装在< code > try /< code>catch块中，然后使用< code > catch 块中的< code>mail步骤发送电子邮件。我会这样写:

try {

    // your pipeline code
    // ...

} catch (e) {
    mail subject: "${env.JOB_NAME}#${env.BUILD_NUMBER} - Failed",
         body: """
 Build: ${env.BUILD_URL}

 Error message: 
 ${e.getMessage()}

 Stack Trace:
 ${e.getStackTrace().join('\n')}
         """,
         to: '[e-mail]'

    throw e // rethrow the error so that it gets printed in the job log, and so the job fails
}

您肯定需要批准getStackTrace作为一种“安全”方法，您可能需要对getMessage执行同样的操作。

要记住的是，此try/catch不会捕获“没有这样的DSL方法”错误，根据JENKINS-45469，这似乎不是错误。
