BitBake finds the <filename>printhello</filename> recipe and

<note>
- Rerunning the task without removing the <filename>tmp</filename>
- directory will not result in a BitBake run that prints the
- same console output.
- BitBake uses its Setscene process and determines that
- nothing needs to be re-run.
- If you delete the <filename>tmp</filename> directory and

- at the console.
+ After the first execution, re-running
+ <filename>bitbake printhello</filename> again will not
+ result in a BitBake run that prints the same console
+ output.
+ The reason for this is that the first time the
+ <filename>printhello.bb</filename> recipe's
+ <filename>do_build</filename> task executes
+ successfully, BitBake writes a stamp file for the task.
+ Thus, the next time you attempt to run the task
+ using that same <filename>bitbake</filename> command,
+ BitBake notices the stamp and therefore determines
+ that the task does not need to be re-run.
+ If you delete the <filename>tmp</filename> directory
+ or run <filename>bitbake -c clean printhello</filename>
+ and then re-run the build, the "Hello, World!" message will
+ be printed again.
