Part 8 -- Setup Jenkins and gerrit: Running a job in response to commit on gerrit

Lets create another job called extended_tests on Jenkins. Purpose of this job is to run a set of test cases (in our case, set will contain only one test) whenever new commit arrives on gerrit.

1. Go to Jenkins address.
   New-Item   -->  Freestyle-Project.
2. Under Build-Trigger. Check "gerrit event".
3. Use builder under project name. And master under Branches.
   
   
4. Under "Build" --> Execute Shell, Add following script

   echo "USER=$USER, HOME=$HOME, WORKSPACE=$WORKSPACE, REFSPEC=$GERRIT_REFSPEC"
   cd ${WORKSPACE}
   git clone http://jenkins1@10.10.0.19:8080/builder && scp -p -P 29418 jenkins1@10.10.0.19:hooks/commit-msg builder/.git/hooks/
   cd builder
   bash job_script.sh

5. Commit a patchset on builder.
6. You will see that a pipeline will get triggered automatically.

NOTE: You might need to install Workspace Cleanup Plugin to jenkins.
