Execution failed for task ':app:dataBindingGenBaseClassesDebug'. Error after upgrading to Android Studio 3.2.1

问题

I got the error after making the project:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:dataBindingGenBaseClassesDebug'.

  Parameter 'directory' is not a directory

This started after upgrading to Android Studio 3.2.1

Any ideas what this could be?

回答1:

The following command worked for me.

./gradlew assembleDebug --rerun-tasks

回答2:

I had the same error at build time and it was caused by a binding variable (that declared inside <data></data> with a Java reserved word as name. For instance <variable name="case" type="com.mydomain.Case" />

回答3:

Removing

 dataBinding {
    enabled = true
}

from the gradle worked. I am no longer using data binding in my project, so this could be the reason.
