Android dependency 'com.android.support:support-compat' has different version for the compile

[hjJunior]

I've one project with firebase plugin, but when I add this depedency and try to compile I got this problem

* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'com.android.support:support-compat' has different version for the compile (26.1.0) and runtime (27.1.1) classpath. You should manually set the same version via DependencyResolution

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 3s
Finished with error: Gradle task assembleDebug failed with exit code 1

My app/build.gradle just implemented firebase core implementation 'com.google.firebase:firebase-core:16.0.1'

and on the end of file applied the plugin apply plugin: 'com.google.gms.google-services'

and on build.gradle classpath 'com.google.gms:google-services:4.0.1'
