Regenerate focus.settings.gradle when new module asi added about focus

[rharter]

"Gradle sync" is an IDE process, not a gradle process. I don't know of a way to trigger Gradle tasks when a sync happens without some separate IDE plugin.

We could, theoretically, make the createFocusSettings task an early task and make the focusSettingsFile an input of it so that it runs any time the focus settings file changes, but that's already too late in the process, because the createFocusSettings task would require that all possible projects are configured so that it can load their dependencies, and the existing focus settings file will prevent that from happening.

As it stands I don't see a way to resolve this due to the chicken and egg nature of configuration vs. task execution phases.
