Here's what zeppelin community did, we make a python script to check the
build status of pull request.
Here's script:
https://github.com/apache/zeppelin/blob/master/travis_check.py
And this is the script we used in Jenkins build job.
if [ -f "travis_check.py" ]; then
git log -n 1
STATUS=$(curl -s $BUILD_URL | grep -e "GitHub pull request.*from.*" | sed
's/.*GitHub pull request <a
href=\"\(https[^"]*\).*from[^"]*.\(https[^"]*\).*/\1 \2/g')
AUTHOR=$(echo $STATUS | sed 's/.*[/]\(.*\)$/\1/g')
PR=$(echo $STATUS | awk '{print $1}' | sed 's/.*[/]\(.*\)$/\1/g')
#COMMIT=$(git log -n 1 | grep "^Merge:" | awk '{print $3}')
#if [ -z $COMMIT ]; then
# COMMIT=$(curl -s https://api.github.com/repos/apache/zeppelin/pulls/$PR
| grep -e "\"label\":" -e "\"ref\":" -e "\"sha\":" | tr '\n' ' ' | sed
's/\(.*sha[^,]*,\)\(.*ref.*\)/\1 = \2/g' | tr = '\n' | grep -v "apache:" |
sed 's/.*sha.[^"]*["]\([^"]*\).*/\1/g')
#fi
# get commit hash from PR
COMMIT=$(curl -s https://api.github.com/repos/apache/zeppelin/pulls/$PR |
grep -e "\"label\":" -e "\"ref\":" -e "\"sha\":" | tr '\n' ' ' | sed
's/\(.*sha[^,]*,\)\(.*ref.*\)/\1 = \2/g' | tr = '\n' | grep -v "apache:" |
sed 's/.*sha.[^"]*["]\([^"]*\).*/\1/g')
