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)
at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

if anyone can help me i would appreciated.

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

I had the same issue. Then I compared the project that was previously migrated from Cuba and the project that was created on JMIX from the beginning. The difference was in the task:

compileWidgets {
generate “ru.mycompany.myawesomeproject.widgets.CustomWidgetSet”
includePaths("/io/jmix//widget/", "/ru/mycompany/myawesomeproject/widgets/**")
}

After adding the task to the project which was migrated, the problem gone

Running into the same issue.

I have no custom widgets and hence no compileWidgets task in my build.gradle

@pvbj2606 did you figure out the problem?

@konstantin.st.ivanov any idea?

Hello!

Could you share the build.gradle file? Do you migrate project from CUBA too?

yes, migrating from cuba

The same case as described above. Your build.gradle file doesn’t contain a task to compile widgets. Try to add the following task:

compileWidgets {
    generate "com.company.myapp.widgets.CustomWidgetSet"
    includePaths("**/io/jmix/**/widget/**", "**/com/company/myapp/widgets/**")
}

Also check application.properties, it should contain the following:

jmix.ui.widget-set=com.company.myapp.widgets.CustomWidgetSet

but I don’t have any custom widgets…

com.company.myapp.widgets.CustomWidgetSet will be generated automatically. It will contain information about widgets from UI, charts, etc.
