Build error : BUG ! exception in phase 'instruction selection ' in source set - spring

Question

I have created a domain class named Curr_Stud_Info.groovy
package ads2
import gorm.logical.delete.LogicalDelete
class Curr_Stud_Info implements LogicalDelete{
static constraints = {
current_std nullable: false
division nullable: false
roll_no nullable: false
}
static belongsTo = [student : Student]
static mapping = {student column: id} //this is needed only in belongs to methods for giving relationship to different column
Integer current_std
Character division
Integer roll_no
}
during building this project i am getting error in it's specs file Curr_Stud_InfoSpec.groovy which is
package ads2
import grails.testing.gorm.DomainUnitTest
import spock.lang.Specification
class Curr_Stud_InfoSpec extends Specification implements DomainUnitTest<Curr_Stud_Info> {
def setup() {
}
def cleanup() {
}
void "test something"() {
expect:"fix me"
true == false
}
}
which is grails generated.
error is
Error:Groovyc: While compiling tests of ads2.ads2.test: BUG! exception
in phase 'instruction selection' in source unit
'/home/pathpanchal/PROJECT/ads2/ads2/src/test/groovy/ads2/Curr_Stud_InfoSpec.groovy'
Type is null. Most probably you let a transform reuse existing
ClassNodes with generics information, that is now used in a wrong
context. at
