upstream changeset info in the email-ext notify from downstream project

[michael chiu]

Hi ALL,
           I found many article from you about jenkins email-ext . Can you 
give me some advice about upstream changeset .
I have 2 projects build and test . I would like to include
upstream changeset info when downstream is failed  in the email notification
.
         I have used the groovy temple [${SCRIPT,
template="groovy-html.template"}]in email-ext.
         Any advice will be appreciated.
