How to achieve this through Regex

Answer 1

This is one way to do it

^ERROR: \/var\/lib\/jenkins\/workspace\/[\w+\/]*@script\/Jenkinsfile not found$

Explanation:

^                                          -- start of string
ERROR: \/var\/lib\/jenkins\/workspace\/    -- fixed portion of path
[\w+\/]+                                   -- variable portion
@script\/Jenkinsfile not found             -- fixed portion of path
$                                          -- end of string

The capture group [\w+\/]+ captures variable strings like example/test example or foo/bar/baz/staging

Edit: if the variable part is always 2 words seperated by a slash you can do something like this:

^ERROR: \/var\/lib\/jenkins\/workspace\/\w+\/\w+@script\/Jenkinsfile not found$

Here we are simply using \w+\/\w+, which means: Match any alphabetical character one or multiple times, followed by a slash followed by any word character one or multiple times
