One of my docker application failed to install in docker and due to that the build failed. But the jenkins job continued to run and reported success.

1. Error logs
2. Dockerfile
3. Jenkins job config

When I run docker build from command line, it returns as below, which is same as that in the jenkins console log.
==================
extconf failed, exit code 1

Gem files will remain installed in /usr/local/lib/ruby/gems/2.2.0/gems/snappy-0.0.11 for inspection.
