Kettle7.1在window启动报错

实验环境：

window10 x64

kettle7.1  pdi-ce-7.1.0.0-12.zip

错误现象：

a java exception has occurred

 

问题解决：

 运行调试工具

   data-integration\SpoonDebug.bat    //调试错误的，根据错误明确知道为何启动不了，Y--Y---Y ,在根目录下生成SpoonDebug.txt文件

根据调试日志

Exception in thread "main" 

根据查询得之，
Unsupported major.minor version 52.0，是java-jdk1.8的东西，因此安装jdk1.8在启动就好了!

运行真身
