奇怪的Javadoc警告：可以找到方法

Question

在Maven项目有了这个类：

package test; 

public class A { 
    /** 
    * Used by {@link B#setC(C)}. 
    * Used by {@link A.B#setC(C)}. 
    * Used by {@link test.A.B#setC(C)}. 
    */ 
    public class C { 
    } 

    public class B { 
     public void setC(C c) { 
      System.out.println("hello!"); 
     } 
    } 
} 

给了我这样的警告：

为什么javadoc中说，他无法找到方法？

Answer 1

尝试Used by {@link A.B#setC(A.C)}。
