Grails领域错误

这是我第一次使用Grails，我定义了以下域类Grails领域错误

package ing2015 

class Product { 
    String name, description, location 
    Category category 
    Subcategory subcategory 
    static belongsTo = [Category, Subcategory] 
    Date date 
    static constraints = { 
     name(blank:false) 
     date (blank:false) 
     description(blank:false) 
     location(blank:false) 

    } 
} 

package ing2015 

class Category { 
    String name 
    static hasmany=[product: Product, subcategory: Subcategory] 
    static constraints = { 
     name(blank:false) 
    } 
} 
package ing2015 

class Subcategory { 
    String name 
    Category category 
    static belongsTo = Category 
    static HasMany = [product : Product] 
    static constraints = { 
    } 
}

但是当我试图运行的应用程序，或生成这些领域的任何控制器，它让我这个错误

| Error Error loading plugin manager: No property found for name [product] for class [class ing2015.Subcategory] (Use --stacktrace to see the full trace) 
Error |

我无法找到问题，以前此，控制台给我类似的东西，它不能创建该表的“产品”，也是“类别”

编辑

我只是简单地解决了将“HasMany”改为“hasMany”的问题。但现在我不知道为什么控制台显示我这个

我不相信

static HasMany

由Grails的*（的hasMany必须）正确读取，由这里的代码是适合我的代码：

class Category { 
    String name 
    static hasMany= [product: Product, subcategories: Subcategory] 
    static constraints = { 
     name(blank:false) 
    } 
} 


class Subcategory { 
    String name 
    Category category 
    static belongsTo = [category : Category] 
    static hasMany = [product : Product] 
    static constraints = { 
    } 
}
