Gradle android cannot find symbol Context

Question

I have a java + kotlin android project that builds and runs fine in Android Studio. I am now setting up CI and need to run Gradle from the terminal. But when I run ./gradlew :app:lint I get a lot of errors like this:

symbol:   class Context
location: class ConnectivityMonitor
e: /*******/LocalAppHistory.java:20: error: cannot find symbol
public boolean hasSeenOnboarding(Context context) {
                                 ^

I get the same type of error for Context, CognitoUserSession, Typeface, CognitoCachingCredentialsProvider... and many more. It only applies to the app project and none of the other modules.

The app gradle.build file:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

android {
   compileSdkVersion 27

   }

Answer 1

I may be wrong, once I got this error while switching git branch from Kotlin Compiler that can't find symbols.

I did clear cache then it worked,

rm -rf $HOME/.gradle/caches/

Seems while switching branch previous branch files cached created this issue.

Give a try if you want.
