Ambiguous method overloading for method ****** 异常的解决办法

Ambiguous method overloading for method ****** 异常

前言：关于该异常，我是在*上(https://*.com/questions/33410033/groovy-ambiguous-method-overload)找到解决方案的，大家也可以去看看专业人士说的，本人小白，说的比较通俗，大佬勿怪

异常如下：

Caused by: groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method cn.hutool.core.collection.CollectionUtil#isNotEmpty.
Cannot resolve which method to invoke for [null] due to overlapping prototypes between:
        [interface java.lang.Iterable]
        [interface java.util.Collection]
        [interface java.util.Enumeration]
        [interface java.util.Iterator]
        [interface java.util.Map]

其实就是CollectionUtil.isNotEmpty方法的重载，导致不知道调用哪一个方法了，所以检查一下你传入的参数是否为null 值，就这么简单
