Question

我创建了一个名为Curr_Stud_Info.groovy的域类

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    
}

在构建该项目期间，我的规范文件Curr_Stud_InfoSpec.groovy出现了错误

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
    }
}

这是grails生成的。错误是

我不知道为什么会发生此错误以及如何解决它？

生成错误：错误！源集中的阶段“指令选择”中的异常
