Answer 1

If you look closely you will see that you are trying to reference min on the class org.example.shalu.Task which doesn't exist. It's possible that you are doing something in Bootstrap.groovy?

Answer 2

You probably created a Service which is does not have a coordinating logic between domain classes (that means there is no domain class for that service).

If this is the case, then add : static transactional = false to the service.

class MyService {
    **static transactional = false**
}

Answer 3

oh this one comes when your database setting

either not mapped with exact database``serverrunning , grails can cannot connect to it , check yourpasswordand usernameand check yourdatabase name check yourdata source setting` And check your connection String URL on datasource like

dataSource {
    pooled = true
    dbCreate = "update"
    url = "jdbc:mysql://localhost/yourDB"
    driverClassName = "com.mysql.jdbc.Driver"
    username = "yourUser"
    password = "yourPassword"
}

DUDE!!
