This one is a very tricky bug with android studio and databinding! I had to test all this proposed solutions and some more for an entire day to finally make the databinding compile at least.

So I had to disable all databindind settings in gradle.properties file, just comment these lines or delete them:

android.databinding.enableV2 = true
android.enableExperimentalFeatureDatabinding = true

remove buildToolsVersion from build.gradle and have the following sdk versions:

compileSdkVersion 27
defaultConfig {
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Plus a couple more clean/rebuild invalidate caches and restart, and it FINALLY compiled. AS engineers are great at creating bugs!
