电子邮件扩展插件-无法使BUILD_LOG_EXCERPT正常工作 [英] Email Extension Plugin - can't get BUILD_LOG_EXCERPT to work

问题描述

无论我在BUILD_LOG_EXCERPT中输入什么内容，我所收到的都是一封空正文的电子邮件，因此可以使用一些帮助.

No matter what I put in BUILD_LOG_EXCERPT, all I get is an email with an empty body, thus could use some assistance.

我有一个写入控制台的Java程序. Jenkins控制台输出的片段如下所示:

I have a java program that writes to console. Snippet of Jenkins console output looks like this:

...

在Jenkins作业中，我创建一个Post Build步骤，并将以下行放入Default Content:

In the Jenkins job, I create a Post Build step, and put the following line in Default Content:

${BUILD_LOG_EXCERPT, start="\\b(Parameters)\\b", end="\\b(Threshold)\\b"}

当我触发工作时，我收到的只是一封空电子邮件.但是，如果我添加

When I trigger the job, all i get is an empty email. However if I add

${BUILD_LOG, maxLines=9999, escapeHtml=false}

然后我会在电子邮件中获得完整的控制台输出.有任何想法吗?我正在使用插件的2.40.3版本.

then i get the full console output in the email. Any ideas? I am using version 2.40.3 of the plugin.

推荐答案

好像您的正则表达式找不到任何匹配项，因此您不会得到日志的任何行.这是因为BUILD_LOG_EXCERPT变量使用java.util.regex.Pattern.Matcher.matches()来匹配正则表达式-如果 entire 字符串匹配(仅在

Looks like your regex is failing to find any matches, so you aren't getting any lines of the log. This is because the BUILD_LOG_EXCERPT variable uses java.util.regex.Pattern.Matcher.matches() to match a regex - and this will only return True if the entire string matches (referenced in this SO question). The log parser is running line-by-line, so it's testing your entire line against your regex and failing (since there are characters after "Parameters").

如果您要查找以Parameters开头但后面可能包含字符的字符串，则可以匹配

If you're looking for a string that starts with Parameters but may have characters after it, you can match to

"\\b(Parameters)\\b(?s).*"

将匹配参数"及其后的任意字符串.

which will match "Parameters" and any arbitrary string after it.
