JavaWeb项目调整为gradle项目并解决报错.apache.commons.collections.CollectionUtils.isEmpty(Ljava/util/Collection;)

普通JavaWeb项目调整为gradle项目结构

1、选中项目--configure-convert to Gradle project

2、按gradle项目标准调整代码路径

3、新增gradle配置文件

4、gradle-refresh dependencies 

 

并且在启动项目时有报错如下：

关键字：org.apache.commons.collections.CollectionUtils.isEmpty(Ljava/util/Collection;)Z

原因：commons.collections-3.1.jar包缺失方法。

解决办法：升级为commons.collections-3.2.2.jar

验证通过
