That is actually a good quesiton
The commons-csv project that is used by the camel-csv is not an active project. You can configure the CSV data format using a CSVConfig class. But looking at the class there do not seem to be a skipFirstLine option.
So I have logged a JIRA to improved this
There is another CSV library that has this option, ignoreFirstRecord. Its the camel-flatpack
Thanks Claus for the advise!
I will switch to Flatpack!
