• Type 'ArgumentsGenerationTask' property 'applicationId' is missing an input or output annotation.

Answer 1

I just came across this issue too when upgrading to Gradle 7. Managed to fix it by switching my old navigation safe args plugin to the AndroidX version - Not sure how I missed that during my AndroidX refactor

// From
classpath("android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0")

// To
classpath("androidx.navigation:navigation-safe-args-gradle-plugin:2.4.1")

As mentioned by @mononz, the issue was caused by upgrading Android Gradle Plugin to version 7.0.0 but @Androiderson's comment helped fix the issue as I was already using the AndroidX version. I updated the safe args plugin to version 2.3.5. Navigation Release Notes
