'Could not find or load main class' after upgrading to latest Grails

[Jacek Furmankiewicz]

I am attempting to port an ancient version of Grails to the latest and greatest of everything.
However, when trying to run

    gradlew bootRun

I get this error

    Could not find or load main class

I am not sure why it is not finding my main class, it is sitting in the proper default package name (gsp in the case of this app):

package gsp

import grails.boot.GrailsApp
import grails.boot.config.GrailsAutoConfiguration

class Application extends GrailsAutoConfiguration {
 static void main(String[] args) {
 GrailsApp.run(Application, args)
 }
}



located in 'grails-app/init/gsp/Application.groovy'.

Is there some reason Grails cannot find this class? Do I need to set some other config file to point to it?

Thank you
Jacek

Did you move it around? Try and do a clean

Cheers

Hi,

I am facing the same issue with run-app which is failing at bootRun. And when run >gradlew bootRun i see 

Error: Could not find or load main class <app>.Application

I have upgraded an app from grails 2.4.3 to 3.2.10. I am able to 

1. run the application using Application.groovy
2. generate war file 
   
3. deploy the same in tomcat

I have tried moving around Application.groovy, did grails clean, gradlew clean, project clean in ggts,

Also i can see Application.class sitting under build folder 

Regards,

Ajay
