title: Making a job fail in jenkins
body: <p>This question might sound weird, but how do I make a job fail? </p>
  
  <p>I have a python script that compiles few files using scons, and which is running as a jenkins job. The script tests if the compiler can build x64 or x86 binaries, I want the job to fail if it fails to do one of these. </p>
  
  <p>For instance: if I'm running my script on a 64-bit system and it fails to compile a 64-bit. Is there something I can do in the script that might cause to fail?</p>
