Hi All:
I am very new to roo. Trying to write a sample. When I try adding a field to an exiting domain class roo complains . I have tried the following without any luck.

A)
field date doj --type java.util.Date
java.lang.IllegalArgumentException: Java source code details unavailable for type SRC_MAIN_JAVA/com.stragure.hrms.domain.Employee
...
...
..

B) field date doj --type java.util.Date ~.domain.Employee
You cannot add more than one default option ('~.domain.Employee') in a single command

c) field date --fieldName doj --type java.util.Date --class ~.domain.Employee
Java source code details unavailable for type SRC_MAIN_JAVA/com.stragure.hrms.domain.Employee
java.lang.IllegalArgumentException: Java source code details unavailable for type SRC_MAIN_JAVA/com.stragure.hrms.domain.Employee

I am struggling to find the rite syntax maybe but tab hints lead to commands shown in (c) above but does not work and I am not sure what ava source code details unavailable for type SRC_MAIN_JAVA means...

Regards,
rohit
