Jenkins BUILD_LOG_REGEX（emailext 插件）不匹配多行（dotall）

Question

背景

我正在尝试使用 emailext 插件提供的 BUILD_LOG_REGEX 环境变量来过滤构建日志。我的正则表达式假设匹配“init:”和“Total time”字符串之间的所有内容。我的正则表达式如下init:(.*?)Total\stime

Jenkins emailext代码如下

emailext( 
    body: "${BUILD_LOG_REGEX, regex=\"init:(.*?)Total\stime", maxMatches=10000000, showTruncatedLines=false, escapeHtml=true}",
    subject: 'Test Subject',
    mimeType: 'text/html',
    to: 'noname@gmail.com'
)

构建日志如下

虽然这适用于几乎所有在线正则表达式测试器，但它不适用于 Jenkins。我相信这与 BUILD_LOG_REGEX 宏如何实现 dotall 有关，但我无法让它跨多行匹配。我意识到 BUILD_LOG_REGEX 是使用 java.util.regex.Pattern 实现的。有人可以帮助我吗？

尝试次数

我还尝试了以下正则表达式 init:(?s:.*)Total\stime 并尝试使用 BUILD_LOG_MULTILINE_REGEX （同时使用两个正则表达式），但两者 return 都不匹配。

Answer 1

解决方案BUILD_LOG_EXCERPT

我找到了一个使用 BUILD_LOG_EXCERPT 令牌的迂回解决方案。以下代码示例给出了我使用此令牌查找的结果。

emailext(
   subject: "compile-check failed for $APP",
   body: "${BUILD_LOG_EXCERPT, start=\"init:.*\", end=\"Total\stime.*\"}",
   replyTo: '$DEFAULT_REPLYTO',
   mimeType: 'text/html',
   recipientProviders: [culprits()],
   to: 'noone@gmail.com'
)

未转义的字符串是${BUILD_LOG_EXCERPT, start="init:.*", end="Total\stime.*"}

我仍然对使用 BUILD_LOG_REGEX 或 BUILD_LOG_MULTILINE_REGEX

的解决方案感兴趣
