Unable to find .gwt.xml

Good day,
I have a project in Cuba-platform and tried to migrate to Jmix but i get this error:

Caused by: org.gradle.api.GradleException: Unable to find .gwt.xml file for widgets compilation
at io.jmix.gradle.ui.WidgetsCompile.compileWidgets(WidgetsCompile.java:111)

if anyone can help me i would appreciated.

Please attach build.gradle files of your CUBA and Jmix projects.
