运行时期间构造函数的数量和java.math.BigDecimal的编译时间不匹配

Question

我定义了一个名为BigDecimalWithAttrDisplay的新类,具有以下实现:

class BigDecimalWithAttrDisplay extends BigDecimal{
    String display;
    BigDecimalWithAttrDisplay(String val){super(val)}
    public String toString(){
        "BigDecimalWithAttrDisplay{val=${super.toString()}, display='$display'}";
    }
}

当我尝试运行使用此类的代码时,我得到:

java.lang.IncompatibleClassChangeError: the number of constructors during runtime and compile time for java.math.BigDecimal do not match. Expected 17 but got 18

有什么问题,我该如何解决？

Answer 1

尝试清理您创建的类(重新进行项目的重建).您可能拥有以前编译中的工件.

另一种可能性是您使用的Java 7和Groovy代码使用低于7的版本编译.然后您可能也会遇到问题.(例如参见:Geb - IncompatibleClassChangeError)
