我正在尝试让 AutoBean 中的 @Category(class) 工作。
我有一个简单的工厂
import com.google.web.bindery.autobean.shared.AutoBean;
import com.google.web.bindery.autobean.shared.AutoBeanFactory.Category;
@Category(TestCategory.class)
public interface TestFactory {
AutoBean<Test> test();
}
和类别类
导入 com.google.web.bindery.autobean.shared.AutoBean；
public class TestCategory {
public static String asString(AutoBean<Test> instance) {
return "as a string";
}
}
和测试接口。
public interface Test {
String getValue();
void setValue(String value);
String asString();
}
这三个都在同一个包中。
当我尝试编译 GWT 项目时，我收到以下错误消息

有人有任何线索吗？
