Set Build Name in jenkins job fromjenkins log

by |Published October 9, 2019

I have below description shows in build log. i want to filter the build number from build log and set it as Build_Name.

Example:
My build log shows as like this..
…
…
Build_Number=101.2-a1

it should set build name as 101.2-a1.

I am trying to use “Build Name Set” plugin, but regexpr is not working as expected. Kindly help.
