[SOLVED] Hangs while Configuring CLASSPATH

I had created a new app in grails, and my colleague was trying to access this app after copying this folder to his local machine. Our environments were setup as follows:

GRAILS Version - 2.4.0
GROOVY Version - 2.3.3
JAVA Version - 1.8

Both of our environments matched. When he created a fresh application, grails created the application, however he was not able to run the application. The same was case with the copied application.

After 5 odd minutes the error was thrown into the screen:

C:\MyTrainigs\GroovyApp\test123>grails
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=32m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; sup
| Configuring classpath
| Error Resolve error obtaining dependencies: Failed to read artifact descriptor for xalan erializer:jar:2.7.1 (Use --stacktrace to see the full trace)
| Error Required Grails build dependencies were not found. This is normally due to internet connectivity issues (such as a misconfigured proxy) or missing repositories in grails-app/conf/BuildConfig.groovy. Please verify your configuration to continue.

Only then we realized that this is internet access issue as grails pointed out. We were both accessing the application from corporate network, through internet proxy. The my colleague tried to access internet through data card and it worked. He was able to execute the application.

So if you have tried all other resolutions and if it has not worked, setup your proxy in startGrails.bat and it will work.

The example for setting up this is as below:

set JAVA_OPTS=%JAVA_OPTS% -Dhttps.proxyHost=yourproxyserver -Dhttps.proxyPort=proxyport

Let me know if this works for you.
