以上是发生的错误。
通过代码定位，发生的异常是 java.io.IOException:invalid constant type:18.
通过搜索，网上解决办法是引入如下依赖，最终的解决结果是，模块中要排除javassist依赖，现下看。
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.20.0-GA</version>
</dependency>
引入后，再次重试，还是不行。
曲折的过程不再赘述，kettle的集成的问答很少，没有其它办法还是先沿着这个方向去找。
通过查看依赖，可以使用以下命令输出依赖
输入命令：mvn dependency:tree
如果要输出到文件，找到pom文件的位置 进入命令行
输入： mvn dependency:tree >d:/tree.txt
然后搜索一下看哪里还引用了javassist，最终发现其它模块里引用了ognl里引用了
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
注意groupdId是javassist不是org.javassist
那就把这个忽略掉
<exclusions>
<exclusion>
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
</exclusion>
</exclusions>
因为在这个服务模块中，我不需要使用ognl所以，我是直接把ognl忽略掉。这样项目模块中再也没有javassist依赖了，再次启动成功，不再报如上的错误
