could not generate APK on react native

I create a key with this command :

keytool -genkey -v -keystore first-key.keystore -alias first-key-alias -keyalg RSA -keysize 2048 -validity 1000

and add this to gradle file :

signingConfigs {
        release {
            storeFile file('/home/mohamadreza/keys/first-key.keystore')
            storePassword '1234567890'
            keyAlias = 'first-key-alias'
            keyPassword 'qq-2012'
        }
    }
    buildTypes {
        release {
            // Caution! In production, you need to generate your own keystore file.
            // see https://facebook.github.io/react-native/docs/signed-apk-android.
            signingConfig signingConfigs.release
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }

then I run this command:
cd android && ./gradlew assembleRelease

I got this error:

Could not determine the dependencies of task ':app:lintVitalRelease'.
> Could not resolve all task dependencies for configuration ':app:lintClassPath'.
   > Could not find com.android.tools.lint:lint-gradle:26.4.2.
     Searched in the following locations:
...

my classpath : classpath('com.android.tools.build:gradle:3.4.2')

how can I fix it?
