[R-pkg-devel] Used package not updated - needs java < V 11

[Knut Krueger]

I am using in my Package XlConnect. If the Computer is using Java < 11 
all is working. But if not, the package can not be used.


inside teh functions tehre is an ' @importFrom XLConnect createSheet 
writeWorksheet saveWorkbook

but only used for additional comfort to use excel sheets

The package is usable without XlConnect if I change

Imports:  igraph,chron,gdata, XLConnect
to
Imports:
     igraph,chron,gdata
Suggests:XLConnect

but then I get the error

checking package dependencies ... ERROR
   Namespace dependency not required: ‘XLConnect’

Just now the new version is on my private repository and working with or 
without Xlconnect depending on the java version


How can I submit the package to cran  until XlConnect is working with 
java > 11
