Grails export plugin Throws an Error "No Signature Of Method is allowed"

Hi i am using grails export plugin and added the plugin in dependencies and mime type for excel.

I am passing the data in the below format:

 FileOutputStream output = new FileOutputStream("C:/dummy/test1.xlsx")
 def empDate = [[joindate:2018-01-30,desig:Instructor]]
 List fields = ["joindate", "desig"]
 Map labels = ["joindate": "Join Date", "desig": "Designation"]

 exportService.export("xlsx", output,empDate, fields, labels, [:], [:])

 //Throws an error "No Signature of method is allowed for argument types ....."

Full error is

No signature of method: com.test.ExportService.export() is appl icable for argument types: (java.lang.String, java.io.FileOutputStream, java.util.ArrayLis t, java.util.ArrayList, java.util.LinkedHashMap, java.util.LinkedHashMap, java.util.Linked HashMap) values: [xlsx, java.io.FileOutputStream@10234, [[joindate:2018-01-30, ...]], . ..] Possible solutions: every()

Solution

  • com.test.ExportService.export() indicates that you are using an export service implementation other than the one provided by the plugin. You probably have a locally defined ExportService class that you are using accidentally. Either rename your local class (preferred) or strongly type the injection to the one provided by the plugin.
