Grails 2.3 - run-app not working

Question

I am getting error while running my Grails app.

My application working in Grails 2.1.4.

I am using

Groovy 2.1.*
Java 1.7
Tomcat 7.0.37

I upgraded my application from Grails 2.1.4 to 2.3.0.M1. After I am getting some error like this:

Answer 1

I have answered to a similar question at How to migrate Grails 2.1 to Grails 2.3 application . As a summary, compare Config.groovy & BuildConfig.groovy to the default versions of a new Grails 2.3 app. Make sure your dependencies are in BuildConfig.groovy instead of application.properties and that Tomcat, Hibernate and Scaffolding plugins are correct version and have correct scope (build for Tomcat plugin, runtime for Hibernate).

Answer 2

I saw this line in the error log :

Error Exception in thread "Thread-7" 
| Error java.lang.RuntimeException: Forked Grails VM exited with error

Try to comment-out section grails.project.fork of BuildConfig.groovy

Answer 3

I had the same error and the problem was a letter case difference between the file name and the class name in the code. Make sure your class name and file name match exactly.

For instance I had my file name as OAuthCallBackController.groovy and the class name as OauthCallBackController (notice the lower case 'a')
