Jenkins - Get last completed build status

Question

I know I can call localhost/job/RSpec/lastBuild/api/json to get the status of the lastest Jenkins build. However, since our build runs very long (a couple hours

Answer 1

To get the last successful build number:

curl --user <userName:password> https://<url>/job/<job-Name>/api/xml?xpath=/*/lastStableBuild/number

Answer 2

Try http://$host/job/$jobname/lastSuccessfulBuild/api/json

Jenkins (and Hudson) expose multiple different builds, such as lastBuild, lastStableBuild, lastSuccessfulBuild, lastFailedBuild, lastUnstableBuild, lastUnsuccessfulBuild, lastCompletedBuild.
