Interrupting tasks

This exercise's build.gradle contains a task called dangerousTask. The project keeps track of a riskLevel, which increases when you run dangerousTask. Our reactor will overload and explode if riskLevel grows higher than 100.

  • Run ./gradlew dangerousTask until you reach critical risk levels
  • Run ./gradlew dangerousTask once more (for science!)
  • Q: Did your reactor overload? If so, what went wrong?
  • Overwrite the value in the risk.txt file to 60.

Modify dangerousTask to prevent it from executing if riskLevel could potentially increase past 100. However, do so without modifying anything in the doLast-block.

  • Run ./gradlew dangerousTask and watch your riskLevel rise
  • Q: Is your reactor still overloading?
  • Q: What are the differences between onlyIf, return, StopExecutionException, ./gradlewException? When would you use them?
