I recently started maintaining this plugin and am starting to go through the PR backlog. This change looks good overall! There are only two more things I'd like to see before merging this PR:

• Rebasing the PR against the latest code in master. This will necessitate removing the final marker from notBuiltIfFound and creating a new setter for this field (marked with @DataBoundSetter). As a courtesy warning, please don't change the constructor that is marked with @Deprecated, as that only exists for backwards compatibility purposes.
• Adding new tests to TextFinderPublisherPipelineTest that exercise the feature. I'd suggest adding two new tests: one called notBuiltIfFoundInFile that mirrors unstableIfFoundInFile, and one called notBuiltIfFoundInConsole that mirrors unstableIfFoundInConsole. The implementation of these tests should be trivial if you follow the existing examples.

ah, I thought this was dead. I even ask myself for maintainership, but without any response.
Thanks, I'll update PR later today.
