Dagger: Hilt build fails if set annotationProcessorOptions in gradle

[HiroyukTamura]

I use Room and dagger hilt in my project.
If I set annotationProcessorOptions for exporting schema of room, the build fails.

    android {
        ...
        defaultConfig {
            ...
            javaCompileOptions {
                annotationProcessorOptions {
                    arguments = ["room.schemaLocation":
                                 "$projectDir/schemas".toString()]
                }
            }
        }
    }

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
   > java.lang.reflect.InvocationTargetException (no error message)

Is there any workaround?

Use += to append to the annotation processor options. Currently the use of = overwrites anything else which is set.

thanks so much and I'm sorry for lack of basic knowledge

It's a common occurrence!
