BaseAppGlideModule.java is referenced but I only have a BaseAppGlideModule.kt file, this is the contents. Also the @GlideModule is not resolved.

import com.bumptech.glide.Glide
import com.bumptech.glide.GlideBuilder
import com.bumptech.glide.Registry
import com.bumptech.glide.annotation.GlideModule
import com.bumptech.glide.load.DecodeFormat
import com.bumptech.glide.load.engine.DiskCacheStrategy
import com.bumptech.glide.module.AppGlideModule
import com.bumptech.glide.request.RequestOptions
import com.my.app.util.glide.PaletteBitmap
import com.my.app.util.glide.PaletteBitmapTranscoder

@GlideModule
class BaseAppGlideModule : AppGlideModule() {

    override fun registerComponents(context: Context, glide: Glide, registry: Registry) {
        registry.register(
            Bitmap::class.java,
            PaletteBitmap::class.java,
            PaletteBitmapTranscoder(glide)
        )
    }

    override fun isManifestParsingEnabled(): Boolean {
        return false
    }

    override fun applyOptions(context: Context, builder: GlideBuilder) {
        builder.setDefaultRequestOptions(
            RequestOptions()
                .format(DecodeFormat.PREFER_RGB_565)
                .disallowHardwareConfig()
                .diskCacheStrategy(DiskCacheStrategy.ALL)
        )
    }
}
