Android issue: cannot find symbol

[ghost]

I followed the instructions to a T and can't figure out what the error could be here. Does anyone know why it couldn't find the symbol?

The only difference I can see is I have the following which is a bit different:

@Override
protected List<ReactPackage> getPackages() {
  @SuppressWarnings("UnnecessaryLocalVariable")
  List<ReactPackage> packages = new PackageList(this).getPackages();
  // Packages that cannot be autolinked yet can be added manually here, for example:
  // packages.add(new MyReactNativePackage());
  packages.add(new IntercomPackage());

  return packages;
}

Here is the error

 Task :app:compileReleaseJavaWithJavac FAILED

I forgot to put this:

dependencies {
    implementation 'io.intercom.android:intercom-sdk-base:6.+'
}
