Java正则表达式将模式与异常匹配

Question

My Jenkins task searches the console output to see if the build is stable. It searches this java pattern: exception|error|warning|Segmentation

I have a compile parameter that has -Werror=format-security in it, so Jenkins should not match it. I try this [exception|error|warning|Segmentation][^Werror] but it still finds Werror in the text. How can I make it so it doesn't think my build is unstable because of compile parameter?

Answer 1

You may use

^(?!.*Werror).*(?:exception|error|warning|Segmentation)

See the RegexPlanet demo .

Details

• ^ - start of string
• (?!.*Werror) - there must not be a Werror substring anywhere on the line
• .* - any 0+ chars other than line break chars as many as possible
• (?:exception|error|warning|Segmentation) - one of the values inside the non-capturing alternation group.
