@Team Any update on this issue. Is there any ${CHANGES} variable available in Jenkins. If No, How can I send Git change logs as a parameter to my downstream job.

I can't think of any existing way to do that. upstream blaming stuff kinda does this but not sure if you can get the upstream changes

@David I did get.. If I Passed JobA_Changes=${CHANGES} it is passing "${CHANGES}" as a value. Is any plugin i need to install?

But I can use ${CHANGES, showPaths=true, format="<div><b>%a</b>: %r %p </div><div style=\"padding-left:30px;\"> — “<em>%m</em>”</div>", pathFormat="</div><div style=\"padding-left:30px;\">%p"} in Email-ext plugin but I can assign this variable to any user defined variable in my Execute Shell.

--Raja

is actually a macro not a variable but technically a plugin could be made to set a variable to the results of a macro without too much difficulty.

thanks for your input.. How to change macro to variable. Is there any plugin available or we need to write a script to change it. please give some blog reference to complete this action.

I know of no existing plugins to do it but that doesn't mean there isn't. Its might be possible with a groovy script as well.
