Data binding class not generated in latest studio 3.6

I am using android studio 3.6.1the problem solved after adding viewBinding.enabled = true to android{ in build.gradle :

android {...    dataBinding {        enabled = true    }    viewBinding.enabled = true

Update:Make sure you add apply plugin: 'kotlin-android-extensions' in top of App Module gradle file :

  plugins {    id 'com.android.application'    id 'kotlin-android'    id 'kotlin-kapt'    id 'kotlin-android-extensions' //<--  }

This happened to me as well. The binding classes are actually generated. The project builds fine. Only Android Studio 3.6.1 (or underlying Gradle build system, I do not care) is buggy and cannot see these classes.

As an intermediate solution, I just hacked the source sets (please note that build variants in the fragment below are specific to my project, you need to rewrite it).

android {    ...    sourceSets {        demoDebug {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/demoDebug/out'        }        fullDebug {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/fullDebug/out'        }        espressoDebug {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/espressoDebug/out'        }        demoRelease {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/demoRelease/out'        }        fullRelease {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/fullRelease/out'        }        espressoRelease {            java.srcDirs += 'build/generated/data_binding_base_class_source_out/espressoRelease/out'        }    }    ...}

As pointed by Steve above: In the mean time, we have to patiently wait for Google to fix it...

EDIT

I have just realised it is MUCH more buggy than I expected, the layouts are broken too:

I hope Google will fix this mess soon...

EDIT 2

I have realized again that Android Studio 3.6 is even more buggy than described above.

The execution of existing Espresso tests is broken too.

I strongly discourage everyone from upgrading to Android Studio 3.6.

I the mean time, we will probably downgrade back to Android Studio 3.5.

Just update your Gradle version to the latest. Go to:

File > Project Structure > Gradle Version

And select the latest stable version (currently 6.3). Check also your Android Gradle Plugin Version if it's also pointing to the latest.
