Failed because of mvn verify automatically remove the 2 configs:

-<a name="filecache.minimumFreeSpace.bytes"></a>spark.rapids.filecache.minimumFreeSpace.bytes|Specify the minimum amount of free space in the Spark local disks. When the amount of free space on the Spark local disks drops below this value, cache data will be removed automatically to free disk space. A zero or negative value will disable this feature. In order to avoid full disk errors, set this value as the max disk speed multiples filecache.minimumFreeSpace.checkInterval.|30G|Startup
-<a name="filecache.minimumFreeSpace.checkInterval"></a>spark.rapids.filecache.minimumFreeSpace.checkInterval|Specifies the time interval, in seconds, between checks for free disk space.|5|Startup

Remove them.
If we add filecache configs to doc, should first expose them in the private repo.
