我目前在Pentaho Spoon 5.4.0.1-130上有相当大的工作和运行，但不幸的是，当我尝试在Pentaho Kitchen执行同样的工作时，我一直收到错误：

我不知道会发生什么，所以任何帮助都会受到赞赏。
谢谢你的时间！

谢天谢地，Dirk Trilsbeek是对的！ （见关于这个问题的第一条评论）
问题在于共享数据库连接。一旦我配置 schtasks （Windows任务调度程序）以使用正确的用户，我就没有问题使用Kitchen来执行我的工作。
以下是我目前用于运行任务的配置：
REM call-pentaho-job.bat
c:
cd /d "C:\pentaho\data-integration"
call Kitchen.bat /file:"C:\app\my-job.kjb" /level:Detailed /logfile:"C:\app\logs\my-job.txt"
exit
REM
REM schtasks /create /tn "MY-PENTAHO-JOB" /tr "\"C:\app\call-pentaho-job.bat\"" /ru MYDOMAIN\myuser /sc daily /st 03:00
REM
谢谢你，Dirk！
