我的服务器上有一个PDI Kitchen作业，我在Ubuntu 14.04服务器上使用Crontab运行脚本，一切运行正常。
现在我正在尝试使用Jenkins（安装在同一服务器上）安排它，我收到以下错误：

${BI_SERVER.PORT}是我在kettle.properties文件中定义的变量，所以我的直觉告诉我Jenkins在执行kitchen时没有加载这个文件（但是当我使用Crontab运行它时会自动加载）
关于如何解决此问题的任何想法？我检查过多个Jenkins和Pentaho博客：
https://anonymousbi.wordpress.com/2014/09/17/pentaho-data-integration-scheduling-with-jenkins/
但是这些例子并没有使用Pentaho变量，因此它们与我无关。
答案 0 :(得分：0)
当Jenkins安装在root帐户下时会发生错误，因为它会尝试像jenkins用户一样覆盖文件。为避免这种情况，可以在新用户下进行安装，也可以将根文件的所有权更改为jenkins（不建议用于安全问题）。
另外，将您的kettle.properties文件移至jenkins home（$ JENKINS_HOME / .kettle）
