Grails not running

I am trying to run grails in my laptop, I have installed jdk 1.8.0 and jre8, I have set JAVA_HOME and GRAILS_HOME correctly. When I type %JAVA_HOME% or %GRAILS_HOME% in command prompt, it displays correct paths. But when I try to run any grails command, I get the following error:

My laptop has windows 8. Any help regarding this would be greatly appreciated.

Now Grails 3+ version support java8 and there are lots of feature with new build system and also integrated spring boot. So you can update your project with grails 3+ version. But you need to Change your application architecture cause of spring boot and gradle build system.

for my case, I re-synced the JDK home link. I use quite a few java versions these days.

after install the intrusive jdk1.8.0_51. THE /Library/Java/Home get overridden (maybe in most cases intended). if you just want to play with jdk1.8 and works mainly under other versions, you should link this place back

Switch to Grails 2.5.0 to run on jdk8u40+.

Also, if you are using the IDE GGTS, make sure it is v3.6.4, and that you install Groovy 2.4 from the extensions page to get the show on the road.

grails 2.4 works with jdk - 8. grails 2.1.1 works with jdk - 7.

I was using java8, I tried using java7 and it worked fine! Apparently grails does not work with java8
