Unsupported Embedded data in Domain?

[marsdonne]

i got a gradle error: myproject:ngGenerateAllCommand execution error: null
my environment： grails 3.3.8 java 8 gradle 4.6
my domain like：
class MyDomain {
static class MySubCls {
//some fields
}
//some fields
MySubCls mySubCls
static embedded = ['mySubCls']
}

no embedded data, no error >_<
