Jenkins – Get the build user name in job config

I would like to get the username who triggered the Jenkins job in the Post build task. At first i thought the Build User Vars Plugin could work but than i realize those variables are only available in the Build process but not the post build action.

Luckily, i found a blog post written by Donald Simpson which help me to solve the problem.

• Don’s blog – Getting the current user in Jenkins

So for each Jenkins build, there is an xml which summarizes the details about the build which could be access thru the following url.

• http://<jenkins>/job/<job-name>/<build-number>/api/xml

In order words, just go to a specific build number in the history list and add api/xml at the end.

To get the username, we can make use of the curl command is to access this xml file.

curl ${BUILD_URL}api/xml --silent | xml_grep --text_only userName

So here is a Post build task script to print the username to the console output.

THE_USER="$(curl ${BUILD_URL}api/xml --silent | xml_grep --text_only userName)"

echo "-------------"
echo $THE_USER
echo "-------------"

Done =)
